The movement inside This reference is built with either calibre. The choice changes the price, the rate and the reserve — nothing else about the watch.
| Base | Seiko NH35 or Miyota 8215, automatic | Swiss clone of the maison's own calibre |
|---|---|---|
| Rate | ±15 to 25 seconds a day | ±5 to 10 seconds a day |
| Reserve | About 40 hours | 55 to 70 hours |
| Balance | 21,600 A/h · six beats a second | 28,800 A/h · eight beats a second |
| Servicing | Any watchmaker can service it; parts are everywhere | Serviced by a specialist; finished as the original is |
| Suited to | Wearing daily, keeping simply, spending less | Matching the reference exactly, and glass casebacks |
The Swiss movement is $50 more. That figure buys the rate, the reserve and a movement that reads correctly through a glass back — not a different watch.
Which we would take. If it is to be worn every day and serviced down the road from you, the Japanese is the honest answer. If it has to survive a loupe against the reference — or the caseback is glass and the movement is meant to be seen — take the Swiss.
The exact base calibre for this reference is confirmed in writing, with the QC film, before anything is dispatched. The two movements, explained
- QC film before ship
- 2-year warranty
- Discreet insured express
Add to cart, enter your ship-to details, then pay with crypto — or message the desk. Either way you get a QC film of this piece: reply GL to ship or RL for another. Japanese +$50 · Swiss +$100.

Description
Apf factory exclusively developed the Audemars Piguet Royal Oak Offshore Collection 26420, using an original 1.1 model for its production. The entire watch utilizes the latest German CNC technology, with every detail synchronized with the original. The strap clasp uses the same quick-release technology as the original, allowing for interchangeability. The dial features the latest cross-hatched pattern, exuding a powerful and luxurious feel. The movement uses the highest quality Dandong movement, a perfect replica of the original 4401 movement, making it virtually indistinguishable from the original from both sides. Initial quantities are limited, first come, first served. The initial colors are: 1. Rose Gold (Panda Eye), 2. Popular Desert Yellow (Smoked Dial), 3. Classic Blue Dial (White Eye), 4. Gray Dial (Blue Eye), 5. Classic and Versatile White Panda.
