Quick answer
A Royal Oak Offshore 26401 super clone is a replica of the 44 mm Audemars Piguet Offshore chronograph. Case, dial, bezel, and strap copy the original. Most versions sell between $400 and $900. The original runs caliber 3126/3840. Replica makers use an Asian 7750 base, a copy of the 3126 stack, or a cheaper automatic. No replica matches the original in movement finish, parts supply, or service support.

What the original 26401 is
Audemars Piguet introduced the Royal Oak Offshore in 1993 as a 42 mm watch, reference 25721. The 44 mm Offshore chronograph family came later, and the 26401 references sit inside it. Core specs:
- Case size: 44 mm wide, about 14 mm thick
- Case metals: rose gold and titanium in the 26401 line, steel in the wider 26400 line
- Bezel: octagonal, eight hex screws
- Crystal: sapphire front and back
- Movement: caliber 3126/3840, automatic chronograph
- Power reserve: about 60 hours
- Dial: three counters and a date window at 3 o'clock
- Strap: rubber or leather with a folding clasp
Genuine 26401 watches trade in the tens of thousands of dollars on the used market. That price gap is the reason the replica market exists.
What "super clone" means for this reference
Sellers apply the term to replicas that copy details past the case shape. For the 26401 that means bezel screw heads shaped like the original, dial print with the right letter spacing, subdial positions that sit where the reference puts them, and a caseback with a reference number and serial format that matches the brand's pattern. The term has no formal standard. One seller's super clone is another seller's mid-tier build.

Movements used in 26401 replicas
- Asian 7750 with decoration plates. Common and easy to service. The base is 7.9 mm thick, so the case ends up thicker than the original.
- Clone 3126/3840. A copy of the AP chronograph module stack. Thinner than a 7750, and the subdial spacing comes closer to the reference. Costs more.
- Basic automatic or quartz. Found in low-end listings. Wrong subdial layout. Skip these.
Ask the seller for the movement name and its thickness before you pay. If the answer is "Swiss movement" with no model number, treat it as a sales line, not a spec.
Case, dial, and finish points to compare
- Bezel screw slots: original screws sit flush with a clean slot cut. Replicas show wider slots and rougher edges.
- Dial print: check the weight of the "Audemars Piguet" and "Automatic" text. Copies tend to use heavier ink.
- Date font: the original uses a set typeface. Many replicas use a generic one.
- Caseback engraving: depth and sharpness of the lettering. Ask for close photos.
- Bracelet and clasp: the weak point on most builds. Strap holes and clasp screws show tool marks.
- Weight: a solid rose gold original weighs far more than a gold-plated steel replica. Sellers who list grams are worth a look.
Price ranges
Listings for a 26401 super clone sit near $400 to $900. Builds with a clone 3126 movement and a plated rose gold case go past $1,000 in some shops. Anything under $150 is a different watch with an Offshore dial on top.
Before you buy: a short checklist
- Get the exact reference the replica copies, such as 26401RO or 26401IO.
- Ask for the movement name and the case thickness in millimeters.
- Request photos of the caseback, the clasp, and the movement itself.
- Ask if the watch was pressure tested. Most are not.
- Read the return policy and the warranty length.
- Confirm strap size before ordering. Offshore straps do not fit every wrist.
Limits of any 26401 replica
Replica parts do not interchange with Audemars Piguet parts. The brand will not service or authenticate a replica, and a boutique service center will refuse the watch. Water resistance holds no guarantee unless a watchmaker tests the seals. Resale value sits near zero. In the US, selling counterfeit branded watches is illegal, and US Customs can seize an imported replica. Weigh those facts before you spend.
