History: USS LST-793 LST Flotilla 29, Group 86, Division 172 The Coast Guard-manned USS LST-793 was built by the Dravo Corporation, Neville Island, Pittsburgh, Pennsylvania, and was ferried down the Ohio and Mississippi Rivers to New Orleans where she was commissioned on 5 October 1944. Her first commanding officer was LT G. A. Miller, USCG, who was relieved by Lt. R. R. Emric, USCGR on 6 February 1946. After shakedown exercises in St. Andrews Bay, Florida, and post-shakedown repairs at New Orleans, she took on board LCT-1275 aid crew and departed for Gulfport, Mississippi for loading. Here she received a tank load of barreled asphalt and U. S. Army trucks and departed for Pearl Harbor on 13 November 1944. The 793 arrived at Pearl Harbor on 13 December 1944, via the Canal Zone, where she remained until 27 January 1945, unloading tank cargo and being guaranteed two week availability at the Navy Yard. She then took on two pontoon causeways, two LCMs, 4 LCVPs, and 17 LVTs of the 715th Amtrack Tractor Battalion AUS, pIus 79 operating personnel. Also 58 officers and men of the 58th AA Gun Battery AUS and departed Pearl Harbor on 27 January 1945, for Leyte where she arrived via Eniwetok, Ulithi and Kossol Roads on 25 February 1945. She remained at San Pedro Bay, Philippine Islands until 13 March 1945, where all LVTs and personnel of the 93rd AA Gun Battery were disembarked. Logistics were carried out and she beached and took aboard 208 men of the 77th Infantry, 305th Battalion AUS, also 17 LVTs of the 715th Amphibian Tractor Battalion plus operating personnel and departed for the Okinawa (le Shima) invasion on 19 March 1945. She arrived at le Shima on 26 March 1945, and launched LVTs without difficulty, as well as picking them up again. The LCT-1275 was launched during this period without difficulty. One LSM rammed the 792's stern while anchored off Point Solo causing damage to No. 6 40-mm and gun tub also carrying away stern anchor billboard necessitating jury rig to house same during rest of the operations. Departing the area for Ulithi on 27 April 1945, she arrived 5 May 1945 for logistics and repairs until May 30th. On that date she departed for Leyte arriving 14 June 1945. Here further repairs were completed and from 1 July 1945 to 1 September 1945, she was engaged in carrying aviation units to the Okinawa area from Luzon, Philippine Islands, some typhoon winds being encountered toward the end of the period. She returned to Leyte on 26 August 1945, and proceeded to Batangas, Luzon, Philippine Islands, where she loaded troops and equipment for Tokyo arriving there on 16 September 1945, encountering two typhoons en route during which the vessel took a slight beating. She returned to Manila on September 28th, and loaded more troops and equipment reaching Yokohama on 19 October 1945, via

Manila and Subic Bay and departed on October 27th, returning to Saipan on November 3rd. Departing Saipan on November 11th, she loaded 210 U.S. Navy personnel and reached Pearl Harbor on November 26th, where she discharged personnel. She arrived New Orleans, via San Diego on 15 January 1946 and Orange, Texas on January 21st. She arrived at Lake Charles, Louisiana on 3 April 1946, and was decommissioned there on 29 April 1946. The LST-793 earned two battle stars for her service during World War II.

1. Features

This watch is a solar-powered watch that contains a solar cell in its face that drives the watch by converting light energy into electrical energy. It is equipped with numerous functions including a full-auto calendar that changes the date automatically (day, month and year change automatically through February 28, 2100 including leap years), a daily alarm function that can be set based on a 24-hour clock, and a chronograph function that allows measurement of time in 1/20 second units up to 59 minutes, 59.95 seconds.

2. Before Using

A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean energy battery that does not contain mercury or other toxic substances. Once fully charged, the watch will continue to run for about 9 months without additional charging (when the power save feature is operating). VPower Save Feature When power generation stops as a result of light not shining on the solar cell during the time display or local time display, the second hand stops at the 12:00 position and only the hour and minute hands move to save power. When light once again begins to shine on the solar cell, the second hand advances rapidly to the current seconds and returns to moving at one second intervals.
<Proper Use of this Watch> To use this watch comfortably, make sure to recharge it before it stops running completely. Since there is no risk of overcharging (Overcharging Prevention Feature), it is recommended that the watch be recharged everyday.

4. Functions Unique to Solar-Powered Watches
When this watch becomes insufficiently charged, the second hand automatically moves to one of the words indicating a warning display to inform the wearer of "insufficient charge warning" or "time setting warning". Try to keep the watch charged at all times to prevent it from becoming insufficiently charged.

When recharged

G NIN WAR
If the watch is left without recharging
When the second hand is pointing to the word "SET", it means that the time should be reset. Always make sure to reset the watch to the current time.
Note: The watch will not return to the normal time display unless the time is reset.
When the watch is recharged by exposing to light, the second hand moves from "STOP" position to the "SET" position. Note: Recharge the watch by exposing to light for at least 30 minutes. (Expose the watch to light until the second hand moves to the "SET" position.)
[Case of Forgetting to Reset the Time after Charging due to the Watch Being Insufficiently Charged and then Resetting the Time after Recharging] * If the watch stops as a result of being insufficiently charged, the watch will not return to normal hand movement (normal time display) unless the watch is sufficiently recharged and the time is reset.

[Stopped]

Always make sure to expose the watch to light and recharge.
Note: Always make sure to reset the watch to the current time.
<Insufficient Charging Warning Feature>
Regardless of the display of the watch at the time, when the watch becomes insufficiently charged, the watch changes to the time display and the second hand moves to the CHARGE position to inform the wearer that it is insufficiently charged. After the second hand moves to the CHARGE position, the watch changes to the time display in the order of the 24 hour hand, hour hand, minute hand and date wheel (function hand). Although the watch continues to keep time accurately at this time, the watch stops after about 5 days have elapsed (roughly 2 days in the case the hands have been moved to switch the time when the insufficient charging warning feature is activated). When this happens, charge the watch by exposing to light so that it returns to one-second interval movement. However, since the time is incorrect when the watch is exposed to light and changes to the insufficient charging warning display after it has stopped due to insufficient charging, set the time after sufficiently charging the watch. Notes: Chronograph measurement stops and the chronograph is 7 reset even when measurement is in progress. The set time (time difference) is retained for the local time. The alarm will not sound even if it is set. Crown (mode switching) and button operations will not function.
<Time Setting Warning Feature>
When the watch is recharged by exposing to light after it has stopped, the second hand moves to the SET position to inform the wearer that the time is incorrect. Although the 24 hour hand, hour hand and minute hand will begin to move after the second hand moves to the SET position, since the time is incorrect, reset the time and date after sufficiently charging the watch. Notes: Crown and button operations will not function except for time and calendar setting operations. When the crown is pulled out to position 2 (time correction position) in the time or date setting mode, the time setting warning feature is canceled. The second hand will remain stopped at the SET position unless the crown is pulled out to position 2 and the time is set. In the case the watch has stopped due to insufficient charging, a minimum of 30 minutes are required until the watch 7 changes to the time setting warning display even if sufficiently exposed to light.

<Overcharging Prevention Feature>
The overcharging prevention feature is activated when the secondary battery is fully charged so that it is not charged further.
<Power Save Feature> When power is no longer generated as a result of light not shining on the solar cell when the watch is in the time/calendar mode or local time mode, the second hand moves to the 0 seconds position and stops to save power by reducing current consumption. The 24 hour hand, hour hand and minute hand continue to keep the correct time even though the second hand is stopped. Furthermore, the calendar is corrected in coordination with the 24 hour hand, hour hand and minute hand. During normal hand movement, when power generation is resumed after the second hand stops at the 0 seconds position, the second hand is rapidly advanced to the current seconds and begins one-second interval movement. However, when the insufficient charging warning feature has been activated, the second hand moves to the CHARGE position and stops, 7 and when the time setting warning feature has been activated, it moves to the SET position and stops. When the watch has stopped, the second hand moves to the STOP position and remains stopped.

24.6.8.2 12.6.4

Note: During the time the secondary battery is fully charged and the overcharging prevention feature is operating, the power save feature does not operate even when power generation is interrupted as a result of not exposing the solar cell to light. Similarly, the power save feature will also not operate when the secondary battery has temporarily become fully charged as a result of exposure to intense light.
5. General Reference for Charging Times
The time required for recharging varies according to the model of the watch (color of the dial, etc.). The following times are shown below to serve only as a reference. * Recharging time refers to the amount of time the watch is continuously exposed to light.

6. Notes Regarding Handling of this Watch
<Try to keep the watch charged at all times.> Please note that if you wear long sleeves, the watch can easily become insufficiently charged as a result of it being concealed and unable to be exposed to light. When you take the watch off, try to place it in as bright a location as possible to ensure that it always keeps the correct time.

CAUTION

Charging Precautions
Inside an ordinary office
60-70 cm (24-28in.) under fluorescent light (30W) 20 cm (8in.) under fluorescent light (30W)

Outdoors, cloudy weather

Outdoors, summer, under direct sunlight 1.5 minutes
Full recharging time : Time required for recharging the watch from the stopped state to fully charged. Charging time for 1 day of operation : Time required for recharging the watch to run for 1 day at 1-second interval movement.
Avoid recharging at high temperatures (over about 60C/140F) since this may result in damage to the watch during recharging. Examples: Charging the watch in close proximity to an incandescent lamp, halogen lamp or other light source that can easily reach high temperatures, charging the watch in a location that reaches high temperatures such as on a car dashboard. When charging the watch with an incandescent lamp, always make sure the watch is at least 50 cm (20 in.) away from the lamp so that it does not reach excessively high temperatures during charging.
7. Replacing the Secondary Battery
Unlike ordinary batteries, the secondary battery used in this watch does not have to be periodically replaced since it is able to be charged and discharged repeatedly.
8. Switching the Mode (Display Function)
This watch is equipped with four modes consisting of time/calendar, chronograph, local time and alarm. Since the mode changes when the crown is turned, the current mode can be confirmed with the mode hand.

11. Using the Chronograph
The chronograph is able to measure time up to a maximum of 59 minutes 59.95 seconds in 1/20th second units, after which it resets to 0 seconds.
Second hand (chronograph seconds) (A)
Function hand (chronograph minutes or chronograph 1/20th seconds
[Explanation of Hands During Chronograph Measurement] When the crown is turned and the mode hand is set to the chronograph [CHR] mode, the second hand and function hand are rapidly advanced to the 0 position and the watch enters the chronograph mode. Second hand: Switches to the chronograph second hand. The second hand advances rapidly and makes one revolution only when starting at 0 seconds, after which it moves in 1 second increments to measure chronograph seconds. Function hand: Switches to either chronograph minutes or chronograph 1/20th seconds. The function hand moves in one minute increments to measure chronograph minutes. When button (B) is pressed when the chronograph is stopped, the function hand switches to 1/20th seconds display during time button (B) is pressed. Note: 24 hour hand, hour hand, minute hand, date wheel: Continue to display the current time when the watch has been switched from the time/calendar mode. Continues to display local time when the watch has been switched from the local time mode. Continues to display the alarm set time when the watch has been switched from the alarm mode.
[Chronograph Measurement] 1. Turn the crown to set the mode hand to the chronograph [CHR] mode. 2. Press button (A) to start and stop the chronograph. A confirmation tone is heard whenever button (A) is pressed. 3. Continuously pressing button (A) when the chronograph is stopped causes the chronograph second hand and chronograph minute hand to be reset to the 0 position.

12. Setting Local Time

The local time function allows the time in a different time zone to be set separately from the current time. Local time is set by performing a time difference correction in 1 hour units based on the current time (time of the time mode/TME). The minute and second hands move in coordination with the current time. [Time Difference Correction Procedure] 1. Turn the crown to set the mode hand to the local time [L-TM] mode. 2. Pull out the crown to Position 2 (local time setting position). 3. Click the crown to the right or left to correct the time difference. 7 (2) When the crown is clicked to the right, the hour hand moves by 1 hour in the clockwise direction. When the crown is clicked to the left, the Local time setting position hour hand moves by 1 hour in the counterclockwise direction.

(A) Reset Measurement

(A) Stop (A) (A) Pressed continuously

Note: The hour hand is not advanced rapidly even if the crown is continuously clicked two or more times. Perform correction accurately 1 hour at a time. Furthermore, the range of time difference correction is 23 hours based on the current time. 4. Always make sure to return the crown to the normal position after correcting the time difference. Note: If the hour hand passes 12:00 AM (midnight) during correction, the date is advanced by 1 day following completion of hand movement. If the time difference is corrected in the counter-clockwise direction and the hour hand passes back over 12:00 AM, although the date is corrected following completion of hand movement, since the date is corrected by 30 days in the clockwise direction, it takes about 2-3 minutes for the date to be corrected. Pay attention to AM and PM when correcting time difference. Note: When returning the time difference to the original setting, return the hour hand in the direction opposite that when the time difference was corrected.

13. Using the Alarm

The alarm function uses a 24-hour clock. Once the alarm has been set, the alarm sounds for 15 seconds when the set time is reached once a day. The time at which the alarm sounds applies to the time (TME) mode, and cannot be set based on the local time (L-TM). [Setting the Alarm Time] 1. Turn the crown and set the mode hand to the alarm [ALM] mode. (A) Second hand: Moves rapidly to the ON or OFF position. 24 hour hand, hour hand, minute hand: (2) 7 Move the previously set alarm time. Function hand: Stops at the 0 position. (B) 2. Pull out the crown to Position 2 (alarm setting position). Alarm setting position The alarm setting is turned ON automatically.
3. Click (turn) the crown to set the alarm time. (1) Clicking once to the right causes the hour and minute hands to move clockwise. (2) Clicking once to the left causes the hour and minute hands to move counterclockwise. Turning the crown rapidly (continuously clicking two or more times) causes the hands to advance rapidly. When stopping the hands, click the crown once to the right or left. When the hands are not stopped manually, they stop automatically after being corrected by 12 hours. Set the alarm while making sure to not to mistake AM and PM by referring to the 24 hour hand. 4. Return the crown to the normal position after setting the alarm time.

[Switching Alarm ON and OFF] The alarm is switched ON and OFF each time button (A) is pressed when the crown is pulled out to Position 1 or Position 2 in the alarm mode. [Alarm Tone Monitor] When button (A) is pressed with the crown in the normal position in the alarm mode, the alarm tone sounds for as long as button (A) is pressed. [Stopping the Alarm Tone] Press either button (A) or (B) to stop the alarm tone while it is sounding.

14. All-Reset

This watch may not function properly as a result of being subjected to the effects of static electricity or strong impact and so forth. When this happens, set the hands of the watch to their respective base positions according to the following procedure after performing the all-reset procedure.
When performing the all-reset procedure, first make sure that the watch is fully charged and the second hand is moving in one second increments. If the all-reset procedure is performed when the watch is insufficiently charged, it may not function properly or remain stopped following the all-reset procedure. 1. Turn the crown to set the mode hand to the chronograph [CHR] mode. 2. Pull out the crown to Position 2 (0-position correction mode). Each of the hands and date wheel move to their respective 0 positions stored in memory and then stop. 3. Press buttons (A) and (B) simultaneously and then release. Following a confirmation tone, each of the hands perform a demonstration movement in the order of the function hand, 24 hour hand, hour hand, minute hand and second hand to indicate that the all-reset procedure is finished. Note: Following the all-reset procedure, make sure to properly reset each mode after performing 0-position correction for each hand before using the watch. The watch will remain stopped and not run unless 0-position correction is performed.

Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time. Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen. Do NOT subject the watch to a strong shock such as dropping it onto a hard floor. Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.
