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

Description
BBS Audemars Piguet Royal Oak collection, a complex functions perpetual calendar watch. Reference: 26574ST.OO.1220ST.01. The only watch in the industry to replicate the original functions.
The Audemars Piguet Royal Oak collection perpetual calendar watch, a noble timepiece, features a noble and elegant blue dial paired with a cool, stainless steel case, perfectly embodying Audemars Piguet's aesthetic design and the extremely high level of technology in its complex functions.
The case is made of 316L stainless steel, with a diameter of 41 mm and a thickness of 11.4 mm. The blue dial is engraved with a large "Grande Tapisserie" pattern, and the applied hour markers and faceted hands are coated with a luminous finish. Three sub-dials displaying calendar functions, along with a moon phase display, are symmetrically arranged on the dial, neatly displaying the hours, minutes, day of the week, date, week calendar, month, moon phase, and leap year information. Truly unique and accurate to the original. The sapphire crystal anti-reflective treatment enhances the overall clarity and brightness of the watch.
Equipped with a 1:1 customized 9015 engine, replicating the Calibre 5134 automatic winding movement. A truly top-tier product.
The watch's serial number is Ref. 26574ST.OO.1220ST.01
