Anyone who knows their way around can get a real bargain when buying a vintage watch. But before you buy an authentic vintage watch, whether, from prestigious brands such as Rolex, Omega, and Patek Philippe, or lesser-known brands, there are a few things to consider. Check The Watch’s Revision And Service History. Don’t expect to receive bills from the 1950s or 1960s when you buy your vintage watch. The vintage watch must be fully functional and in good technical condition. If not, finding spare parts available (at fair prices) can be a challenging endeavor. I had to wait more than a year for a replacement part for the movement of one of my 1950s Omega watches. Only a few watchmakers can produce spare parts themselves or reuse parts from another direction. It is always best if the manufacturer has serviced the vintage watch directly. But of course, it is sufficient if it can be proven. When a watch like the rolex submariner (โร เล็ก ซ์ submariner which is the term in Thai) is more than 30 or 40 years old, the original packaging and papers are often missing. If possible, make sure you get the correct box for your watch. The package should match the watch or at least come simultaneously. Because over the years, many watch manufacturers have changed the packaging of their products. Some watch brands can also provide you with the correct information about the original boxes and papers. The Right Guarantees Of Origin Another critical issue is the origin of the vintage watch. Be very careful if the seller shows you items that are supposed to prove the watch’s supposed origin. These include photos of people who wear the watch or napkins with the initials of the first owner. Unfortunately, this is not a joke. Some watch fans have fallen for such tricks. Realize that only genuine guarantees of origin count. This includes invoices stating the correct serial and work number and evidence of the work carried out on the watch or original papers with a stamp or guarantee certificates. Do not pay for watches that appear dubious to you or show signs of being put on the market with dishonest intent.
