How is the water resistance of Longines watches?

　　The so-called water-resistant watches are never 100% completely sealed, but rather prevent moisture from entering to varying degrees depending on the construction method and defined testing methods. Making an item completely waterproof is theoretically feasible, but in most cases it has no benefit and is therefore unnecessary. Longines watches are loved by many for their excellent quality, and Longines watches also have a certain degree of water resistance. So, what is the water resistance of Longines watches like? Below, the editor will introduce the water resistance of Longines watches.

　　Water resistance of Longines watches

　　1. Watches use a pressure resistance value to test their water-resistant performance to indicate their water-resistant depth. This is a reference theoretical pressure, and the unit is expressed in atmospheres (3AMT = 30 meters depth pressure). This is not the actual diving depth used. At the same time, many water-related activities involve a lot of movement and other environmental changes. These factors, which are not taken into account when rating the watch's water resistance depth, may greatly reduce its water-resistant performance or even cause it to fail.

　　2. The water-resistant performance of a watch is not permanent and may be affected by the aging of the waterproof gasket or accidental impacts on the crown. Therefore, it needs to be regularly checked at an authorised service centre.

　　Water resistance levels of water-resistant watches and their corresponding application ranges

　　1. Water resistance level one: Water resistance up to 30 metres / 100 feet or water resistance up to 50 metres / 165 feet, can only prevent splashing water drops and rain.

　　2. Water resistance level two: Water resistance up to 100 or / 330 feet or water resistance up to 200 metres or 660 feet, can prevent splashing water drops and rain, and can be worn for swimming.

　　3. Water resistance level three: Water resistance up to 300 metres / 1000 feet, can be worn for free diving or water sports.
