Know About Durability and Reliability
Reliability is a key factor in choosing a watch -- especially a sport watch. To be deemed water resistant, most fine watches are subjected to a pressure test equivalent to a diver's depth of 100 feet. If the watch shows no sign of internal humidity or damage, it can be called 'water resistant'. Degrees of water resistance vary: 50 meters is almost standard, but many watches are resistant to several hundred meters or more. Chronometers, that are tested in a Swiss observatory under stringent conditions in various positions, and extreme temperatures, heights and depths, and are then certified, are considered among the more reliable and durable wristwatches.
Look for Warranties and Guarantees
Every watch manufacturer offers some warranty on its timepieces. Typically, the warranty is for one year, but some companies offer several years and some even offer extended warranties that cover the case or bracelet as well as the movement. Make sure the watch comes with its original packaging, boxing and informational materials. Be sure to get a detailed, itemized receipt.
Ask About After-Sales Service
Before buying, know about the back-up support of the brand and the retailer. Be sure to find out if the retailer has an after-sales service facility on premises if repairs are needed, and if the brand has a U.S. service center.
