Short answer
Replica 5105 v7 is a replica watch listed under a seller-made label. The 5105 points to the Patek Philippe reference the watch copies. The v7 is a version number. No brand, factory registry, or standards body assigns that number. Two sellers can list a v7 and ship different watches. Ask for written specs and test data before you pay.
What the two numbers mean
The model number ties the replica to a target design: case shape, dial layout, hands, and caseback. The version number is an internal label. In most listings v1 to v7 marks changes to dial print, case thickness, movement, or bracelet. Sellers seldom publish a changelog. Treat v7 as a claim, not a specification. The factory that started the v-series labels is not documented in public sources.
Specs to confirm in writing
- Case diameter and thickness in mm, measured with calipers.
- Movement name, beat rate, power reserve, and whether it is a clone or a decorated generic.
- Crystal material and coating.
- Dial print method and index alignment.
- Lug width and strap or bracelet material.
- Stated water resistance and the test method used.
- Weight in grams.
- Caseback engraving text and depth.
Quality control evidence
Request dated photos, not stock images. A timegrapher photo should show rate in seconds per day, beat error in ms, and amplitude. Ask for a short video of the seconds hand and a close dial shot at 3x. If the seller claims water resistance, ask for the test result and the standard used. ISO 22810 covers water resistance marking for watches.
Red flags
- Version numbers with no list of changes from the prior version.
- Photos reused from another seller.
- No timegrapher data.
- 1:1 claims without measurements.
- Pressure test claims without a stated method.
Price and version claims
A higher version number does not prove a better watch. Compare the parts list, not the label. Ask what changed between v6 and v7. If the seller cannot name the change, the label carries no weight. Price gaps between labeled versions should match named parts changes.
Legal risk in the US
Counterfeit watches are illegal to import and sell in the United States. CBP can seize shipments. A purchase carries risk of loss and no warranty. This page describes how listings are labeled. It is not advice to buy counterfeit goods.
