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
masterpiece, the HUBLOT BIG BANG Unico Rainbow Watch, part of the Big Bang collection, features two new rainbow watches. These watches incorporate colored gemstones, creating a dreamlike and dazzling effect with multiple color gradients. The position, number, and size of each gemstone are precisely matched to the original specifications. The watch is a custom-made Hublot exclusive UNICO HUB 1280 automatic flyback chronograph movement. Features include a skeleton date ring at 3 o'clock, a 60-minute counter on the 3 o'clock dial (note: most 7750 movements on the market only count 30 minutes), a horizontal clutch at 8 o'clock, a small seconds wheel at 9 o'clock, and sapphire crystal hands with a rainbow pattern—the quality is impeccable. The 45mm case boasts 100% perfect functionality, reaching the pinnacle of craftsmanship. We welcome collectors to appreciate its excellence. (Produced by ZF as a fine piece)
