Even if you’re an expert in watches, it can be hard to tell a real Patek Philippe from a fake. To authenticate your timepiece properly and make sure you have a genuine Patek Philippe on your wrist, familiarize yourself with the hallmarks of authenticity – including hallmark stamps, references numbers, and serial numbers.
Check the Brand Logo and Packaging.

Start by inspecting the logo. It should be prominently displayed in a number of places throughout the packaging. Believe it or not, many fake Patek Philippes fail to properly replicate this detail, evident in small imperfections or visible flaws. You should also check the text associated with all documentation – from the paperwork to the box itself – and ensure that it is all consistent, with no sign of typos, spelling mistakes, or other discrepancies.
Look at the Bracelet and Clasp of Your Watch.

All authentic Patek Philippe watches have the iconic shape of their bracelet and clasp, so take the time to take a closer look. Pay attention if there are any irregularities, such as if some of the links aren’t completely circular or if the folding clasp doesn’t feel secure. Also situated on either side of the folded parts of the clasp is the stamping of their hallmark. It should easily be identifiable with a few stamps in their signature font.
Examine the Movement of the Hands and Date Window.
The movement of the hands and date window should appear smooth, accurate and continuous. Check by analysing the movement from a few minutes after midnight to the next day. The date should remain consistent throughout this test; any skipping or irregularities in the motion means it could be a counterfeit Patek Philippe watch. Additionally, take a closer look at the calendar window to check if its font corresponds with official Patek Philippe watches—their branding looks very similar in all official timepieces.

Research Serial Numbers and Production Dates.
To help verify whether the watch is real, you should take note of the serial numbers on the case and movement. You can match these up with official records of the dates on which they were released, as well as when and where they were produced. On all real Patek Philippe watches, each model number starts with different numerals – from 1 to 8 – that serve as a reference to various boutique areas or production dates. Furthermore, thoroughly inspect all crown seals; fake watches tend to use similar patterns for this feature and might not correspond to standard ones.
