The pick before the comparison
Buy the top-tier 26470 replica with the decorated clone 3126/3840 movement and the 42 mm case first. That tier is the only one worth setting next to a genuine Offshore, because it copies the case profile, the dial layout, and the bracelet geometry closely enough that the differences live in the finishing rather than the silhouette. Lower tiers are not a cheaper version of the same watch. They are a different object, and the gap shows in the first thirty seconds on the wrist.
Prerequisites before you handle either watch
- A 10x loupe or a phone macro lens
- The exact reference you are matching, for example 26470ST.OO.A002CA.01 in steel with a black dial
- The factory spec sheet for that reference: 42 mm case, Calibre 3126/3840, sapphire front and back
- A matte surface, a soft cloth, and a daylight lamp
- A caliper, if you want the thickness question settled in one measurement
How to compare them in eight steps
- Set both watches to the same time and date, then let them run for a full day before you judge anything.
- Measure case diameter and thickness with the caliper. The genuine 26470 sits near 14 mm; most replicas add half a millimeter to a millimeter and a half through the caseback and the movement spacer.
- Turn the case in raking light and compare the brushing. Genuine satin finishes run in tight, even lines across the bezel and the case flanks; replica brushing is coarser and often runs in one direction across surfaces that should change direction.
- Run a fingertip along the bevel between the brushed flank and the polished edge. A genuine chamfer is crisp and narrow. A replica chamfer is wider and softer, and you can feel the roll.
- Check the dial under the loupe. Count the Méga Tapisserie squares across the center line and compare the depth of the cut, the sharpness of the inner corners, and the flatness of the top surfaces.
- Push each chronograph pusher and note the travel. Genuine pushers have a short, firm stroke with a clean start; replica pushers feel longer and spongier.
- Reset the chronograph and watch the hands snap back. Both should return to zero in one motion with no hesitation at the twelve.
- Flip the watch and inspect the caseback engraving, the serial depth, and the rotor finishing. Genuine engraving has a crisp edge and a consistent depth; replica engraving is shallower and loses the fine letterforms.
The options, in order
Option 1: top tier with clone 3126/3840
This is the pick. It carries the correct subdial positions, a properly decorated movement bridge, and a bracelet with the right taper. Expect the closest match on the wrist and the highest price of the three.

Option 2: mid tier with a modified A7750
The A7750 gives the correct 12-6-9 subdial layout, which is why it is used so widely. The trade is thickness and a rotor that sounds lighter than the genuine. Buy this tier if the budget is fixed and the watch will be worn under a cuff.

Option 3: entry tier
Skip it for comparison purposes. The dial printing, the date font, and the bracelet screws give it away at arm's length, and no amount of adjustment closes that gap.
Where every replica loses to the original
- Movement: the genuine Calibre 3126/3840 is a 365-part column-wheel chronograph with roughly 60 hours of reserve. No clone matches the part count, the winding feel, or the service interval.
- Water resistance: the original is rated and tested at the factory. A replica is not pressure tested, so treat it as splash resistant only.
- Lume: genuine Super-LumiNova is applied in an even layer and glows for hours. Replica lume fades within minutes.
- Strap and clasp: genuine rubber has a specific durometer and the clasp engraving is deep. Replica rubber is stiffer and the clasp lettering is shallow.
What to do with this
Buy Option 1, run the eight steps, and keep the original's spec sheet beside you while you do it. If the case thickness or the pusher feel fails the test, return the watch and move to the next seller rather than the next tier.
