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
