Essential maintenance tips for Longines mechanical watches

　　Introduction: Nowadays, watch maintenance is receiving more and more attention, as everyone wants to avoid the frustration of a newly purchased watch developing issues shortly after use. Therefore, mastering the basics of maintenance is very important. Below, our editor will discuss the care of Longines mechanical watches from three aspects, and we hope this proves helpful to you!

　　What are the maintenance tips for Longines mechanical watches?

　　1 One of the most important aspects of maintaining a Longines mechanical watch is its water resistance. Water ingress typically occurs for two reasons: engaging in activities that exceed the watch's water-resistance rating, or exceeding the service interval resulting in compromised waterproof gaskets and other components. Therefore, you should first check whether the watch is due for a service, and verify the water resistance required for your travel destination or planned activities. Generally, timepieces need to be serviced every 3 to 4 years to prevent the waterproof gaskets from hardening or the lubrication from drying out, which can cause mechanical movement issues.

　　2 When servicing a Longines mechanical watch, it is necessary to understand its water-resistance rating. A rating of 30 metres is generally sufficient for everyday business wear. However, leisure travel requires higher water resistance: surface water activities are best suited for watches with a water resistance of 50 metres or more, while underwater activities require at least 100 metres. The reason for this is that watchmakers test water resistance under static conditions without the watch being worn on the wrist. When worn by a wearer engaging in active movement, the skin generates water vapour. Water vapour molecules are much smaller than liquid water, increasing the likelihood of vapour entering the case and causing a fault. Underwater activities introduce dynamic fluctuations and unstable water pressure, which can easily force water into the watch, making water resistance even more critical.

　　3 If you are travelling abroad, you should also check the dual-time function. Dual-time or world-time complications help manage different time zones and make a great choice. Dual-time watches allow two different times to be easily read on the dial, and with a simple setting, you can keep track of the time difference between locations. World-time watches feature the names of major global cities engraved on the dial; by pointing the city name to the set marker, you can read the local time in that city. Both are practical ways to manage time differences. Taking the Patek Philippe world time watch as an example, the dial indicates the representative cities across 24 time zones, giving you a clear overview of times in major cities worldwide.
