Precautions for Calendar Watch Maintenance

　　Answer: The day and date should not be adjusted between 21 o'clock and 3 o'clock in the early hours, because the jumping of the calendar is driven by gears and happens slowly. Adjusting it yourself can cause significant damage to the watch.

　　Q2: What should be noted when adjusting a perpetual calendar watch?

　　Answer: The adjustment method for perpetual calendar watches varies greatly depending on the brand, so it is best to refer to the instruction manual. This is because almost all perpetual calendar functions prohibit setting the time backwards. The best way to maintain the perpetual calendar function is to ensure that the movement operates normally and never adjust it. The safest approach is to purchase a “ watch winder ” so that the watch can be wound by it when not being worn, preventing it from stopping.

　　Q3: What is the maintenance interval for a calendar watch?

　　Answer: Not just calendar watches, all mechanical watches need to be sent to a professional institution for a comprehensive service every 4-5 years under normal wear. Due to long-term wear, the movement balance wheel will experience friction and wear, and watch oil provides good lubrication during this friction process. Over time, the watch oil will gradually dry up, and the subsequent wear will progressively increase. Therefore, regular maintenance is essential.

　　Q4: Are there any dust maintenance tips for calendar watches?

　　Answer: Dust might seem unrelated to watches, but that is far from the case, especially for the movement, which is one of the three major natural enemies. If a watch operates in dust-dense areas for a long time, dust can leak into the gaps of the case. These tiny dust particles will cause the watch oil in the movement to dry out rapidly. Naturally, this is a bad thing for the movement. However, we do not often encounter heavily dust-dense environments in daily life, but it is still necessary to have a cloth on hand to wipe it down at appropriate times.

　　Q5: Common knowledge on shock maintenance for calendar watches?

　　General dress watches are relatively “ fragile ” and are not as rugged and sturdy as sports watches, because movements with more complex functions are usually more susceptible to damage, especially when subjected to sudden, severe shocks. Some people who enjoy playing golf do not wear watches because the momentary G-force experienced by the wrist during a swing is astonishing. While this level of force has little impact on human bones, it delivers a considerable shock to a watch worn on the wrist.
