How to use your Longines chronograph
Your chronograph is a precise and reliable timepiece for everyday use. It is driven by a Longines L652 automatic movement. The case is waterresistant and tted with a sapphire-crystal glass. As a watch, the chronograph shows the hours, minutes, seconds and the date. Using the chronograph, you can time events lasting up to 12 hours to the nearest fth of a second. The three-position crown 1. Pushed in against the case Winding: The natural movements of your wrist wind your Longines chronograph while you wear it. Fully wound, it has a power reserve of about 40 hours. Rewind the watch manually if it has stopped through not being worn. 2. Pulled half-way out Setting the date: Turn the crown backwards to change the date, then push the crown against the case. You need to correct the date at the end of months with fewer than 31 days.
Important: Never change the date when the time shows between 8.00 pm and 1.00 am, to avoid damaging the movement. 3. Pulled right out Setting the time to the second: The small seconds-hand stops when you pull the crown out as far as it will go. Set the hours and minutes by turning the crown any direction. To restart the seconds at a broadcast or telephone time signal, push the crown back in against the case. Important: Should your chronograph need repair, it should be sent to a Longines agent only. Making sure your watch is water-resistant Your chronograph is water-resistant. But if it receives a blow, it may lose its water-resistance without you realizing it. Ask for its water-resistance to be checked when you have your watch serviced.

The qualities of mechanical watches and how to preserve them
Why do Longines watchmakers include watches tted with a mechanical movement in their collections, sometimes even in preference to more recent technologies ? Theres a simple answer: watches tted with a traditional handwound or selfwinding movement provide all sorts of satisfactions that no other type of timepiece can match. Of course more accurate time technologies are easy to nd, quartz resonators for instance, but nothing beats mechanical watchmaking for pleasure pure and simple. Incorporating countless technical improvements, todays mechanical movements qualify as marvels of inspired ingenuity, born of centuries of fascinating history and the patient workmanship of some of the worlds nest craftsmen. You need only observe a movements intricate mechanism and rhythmically moving parts, the beauty and neness of its components fashioned in steel as well as in various elaborate alloys and even in gold or platinum, to conclude that you are looking at a shining example of applied intelligence, brought to life by Natures most versatile tool, the craftsmans hand. Whats more, the handwound or selfwinding mechanical movements tted in todays Longines timepieces are precise to within a few seconds a week more than enough for the demands of everyday life.
What is a mechanical movement made of ?
Essentially metal from the most valuable to the most complex. Although the modern watchs earliest ancestor, the steeple clock, was made only of iron, todays wristwatches may contain over a dozen metals, including alloys, spread over hundreds of parts and components. Less than a millimeter thick for the most part, made in an incredible variety of shapes and sizes, some even ner than a human hair, the parts that make up a watch movement are assembled and adjusted, often simply by friction, with extraordinary skill and painstaking precision. Nevertheless, the more compact the movement and the smaller its parts, the more it is vulnerable to the hazards of everyday life and its various parts exposed to daily wear and tear.

A long and useful life

Today, a competently designed and well built mechanical watch movement can run smoothly and well for decades on end, assuming of course that it is treated with care and provided with regular maintenance. It should be remembered that on the wrist, the movement will be regularly exposed to such things as the negative effects of gravity and of magnetic elds, the repeated expansion and contraction of metal parts caused by sharp variations in temperature, much jarring and occasional hard knocks, the presence of moisture or ne particles (talc, for example) inside the case, and of course the slow but steady deterioration of the movements special lubricants, potentially causing friction and jamming.
The selfwinding mechanism
By the late 18th century, a few exceptionally inventive watchmakers had devised a mechanism that made it possible for a watch movement to wind itself automatically, simply by harnessing the wearers body movements. This study in miniaturized horological ingenuity was later adapted to the wristwatch. It works as follows: the normal movements of the forearm impel an oscillating weight, also called rotor, positioned against the movement, to swing around its axis. The weight rewinds a spring which, in every watch of this type, stores the mechanical energy required to keep it running. Automatic winding thus does away with the need to wind the movement manually by the crown every day.

Hand winding if the watch stops
A selfwinding wristwatch normally has a power reserve of over a full day, often some forty hours. But if the watch is not worn for longer than its maximum power reserve, it will stop and will have to be rewound manually before being replaced on the wrist. In such cases, it is best to rotate the crown at least forty times, especially if the watch includes a calendar.
