First, look at the movement, Patek Philippe is currently in the production of mechanical watches, whether female or male form, automatic or manual, more than 95% are through the end of the design, the main movement of the current Patek Philippe 215,315,324,240, 16-250,25-21,27-525,28-20,28-520,29-535 (some have been discontinued), you can see through the bottom of the back cover is more than these movements (with a magnifying glass can clearly see the moment Of course, the premise must be more understanding of the look of these movements, or even through the bottom, it is difficult to distinguish the movement, which need to look more accumulated more Experience can be correctly identified. Patek Philippe quartz watch is only produced for ladies, and completely impermeable, so the difficulty of identification will be higher than the mechanical watch, but Patek Philippe 's production process is a fake table or imitation table is not matched with the, so you can look through the production process , Such as the polished metal strap, case polishing to identify. Second, according to the appearance of the watch, almost all of the Patek Philippe , the watch's back cover will not have any basic brand logo or model, in addition to a limited number of models in the back of the word, the remaining 99% of the models are There will not be any text or logo In addition, Patek Philippe has always been known for its low profile, so almost can not see the brand logo on the watch dial, the current production of only 5180 / 1G, 4937,7180 these three models to watch the brand logo on the front. Third, Patek Philippe started with the production of the Tourbillon watch, never exposing the tourbillon device to the dial, first of all the low-key brand spirit, followed by the interest of the Tourbillon device. We know that Tourbillon (Tourbillon) device is a masterpiece of the clock: Abraham. Louis. Breguet invented in 1795, is generally in order to offset the impact of gravity on the accuracy of the watch invented a tune Speed ​​device, Patek Philippe 's tourbillon is very sophisticated, handmade by 72 small components, total weight of not more than 0.2 grams, even more than a velvet feather light. Tourbillon exposure to some drawbacks, first of all, the tourbillon is a precision instrument, there are also internal oil, if exposed, often receive sunlight, will make the oil volatile, so that the accuracy of travel time, then lost the Tuo The most original meaning of flywheel. If you find the tourbillon bare outside the watch, you can be 100% sure not Patek Philippe watch.
