Tissot to celebrate the 150th anniversary of the birth of its brand, launched the most Tissot- style watch - the Locke automatic series. Its name comes from the birthplace of Tissot - the Swiss town of Locke, is the only use of its birthplace Tissot as a series of watches, but also dedicated to the 150th anniversary of the birth of Tissot 's most memorable gift. Then Tissot li Locke how to maintain? Many people think good watches should be waterproof. Swiss people have different understandings with people around the world. The vast majority of watches waterproof 30 meters or 50 meters. And many people think this means that their own table can be placed in the corresponding depth of water without problems. Wrong! 30 meters or 50 meters in the Swiss watch dictionary means life waterproof. The real meaning is: try not to wet your watch. And only when the water depth reaches 100 meters when it can not be put into the water into the water. A true dive watch often requires a water depth of more than 200 meters. Some people wear a diving table steam sauna. Sauna temperature is much higher than the outdoor normal temperature, instantaneous temperature changes will lead to watch the waterproof gasket premature aging. Even a diving watch may lose its waterproof function before it is required to change the waterproof gasket. In fact, the movement is quite "fragile", especially when it comes to an instant violent vibration. Do not you see a lot of people wearing a high level of formal wear watch golf swing. You know, especially in the tee shot that the moment of the wrist force G is amazing. Although this is not a problem for the human skeleton, it is a real shock to the watch worn on the wrist. A lot of big-name high-end suits are due to the owner's enthusiasm swing was sent to repair center. Many people will have this experience: just bought a mechanical watch inexplicably increased the error. And one of the biggest culprits is magnetism. Due to the modern family and the social environment is full of electromagnetic fields, if you accidentally placed their watch next to the TV at home, it will not take long before it will lead to the movement by magnetic. The significant change after the magnetic is the error of travel time is getting bigger and bigger. Of course, do not panic, in case the magnetic field can go to professional institutions degaussing. In order to save such trouble, it is recommended that the usual watch will not wear away from the strong magnetic field area. Many people seem to have no idea about the need for watch maintenance. The affirmative answer is: Yes! And with the exception of OMEGA's current coaxial movement (which is officially claimed by co-axial movements for 10 years), almost all mechanical watches require every 4-5 years Sent to a professional body maintenance time. Because wear and tear, the movement balance needs more than 10,000 times per minute friction, table oil in the process played a good role in lubrication. Over time, table oil will gradually dry up, and then the wear and tear will gradually increase. For this reason, regular maintenance must be necessary.
