Top pick for most buyers: a 5105 v1 sold by a maker that publishes its movement, its measured case dimensions, and a return window in the listing. That trio beats any set of glamour photos. The four criteria used in this guide are case geometry, movement identity, dial and hand detail, and written after-sale terms.
Replica 5105 v10: What the Version Label Means
Confirm the reference before the version number
“5105” is a number that appears in more than one catalog and in a lot of loose listings, so pin down what the seller is copying before you compare batches. Ask for the brand, the full reference, the case metal, and the era the replica follows. A seller who will not name the source reference is selling a shape, not a watch. Version labels such as v1, v2, and v3 are seller shorthand, not an industry standard, and nothing stops two workshops from both calling a first run v1.
Replica 5105 v9: What the Version Number Really Means
Criterion 1: case geometry
Ask for caliper readings, not adjectives. You want case diameter, thickness, lug width, and lug-to-lug. Compare those numbers against the published specs for the reference. Thickness is where first batches slip most: a case that runs 1.5 mm thick changes how the watch sits on the wrist and how the caseback meets the midcase. Request a straight-on side photo as well, because profile lines hide behind angled shots.
- Good sign: caliper photos with the watch next to a ruler and on a scale.
- Warning sign: dimensions copied from a spec sheet with no measurement of the actual unit being sold.
Criterion 2: movement
Find out what is inside and whether the caseback is solid or display. A v1 with a solid back can hide a workhorse movement and still look right on the wrist. A v1 with a display back has to show a decorated movement, and that is where early batches often look unfinished. Ask for the movement name, beat rate, power reserve claim, and a short video of the seconds hand sweep and crown action. If the seller cannot state the movement, assume the cheapest option available.

Criterion 3: dial, hands, and printing
Zoom in on markers, printing, and hand finishing. Early batches tend to show three faults: printing that sits heavy, indices that sit proud of the dial, and hands with soft edges. Ask for macro photos in daylight rather than studio light. Compare the date window position and the font with reference photos from a resale listing or the brand catalog. Alignment at 12 and at 6 is worth checking in a photo taken dead straight.
Criterion 4: terms after the sale
Get the return window, the warranty length, and the service policy in writing before payment. A v1 is the batch most likely to need a regulation or a hand swap, so a seller who offers a 7 to 14 day return and a stated service address is worth more than one who shaves a few dollars off the price.
v1 versus later batches
- Pro of v1: lowest entry price and the batch that later runs get measured against.
- Pro of v1: many workshops fix flaws in v2 and v3 without moving the price much, so waiting can pay off.
- Con of v1: first-run faults in thickness, printing, and movement decoration are common.
- Con of v1: parts supply for a first batch dries up sooner than for a run that stays in production.
Who should buy the 5105 v1
Buy v1 if you want the reference shape at the lowest cost, you can read caliper photos, and you are comfortable shipping a watch back. Wait for a later batch if the caseback is a display type, if thickness matters to you, or if you plan to keep the watch for years without service. Walk away from the listing if the seller cannot name the movement or will not put return terms in writing.
