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.

Description
Hublot's new Big Bang Skeleton multi-function moon phase watch boasts a distinctly mechanical feel. The Hublot Classic Fusion 517.CX0170.LR
Beneath its rugged exterior lies a three-piece case. The bezel edge sandblasting and case polishing details demonstrate meticulous attention to detail. The bezel edge screws are custom-made H-shaped titanium metal screws, with sharply defined edges upon close inspection. The skeleton-style moon phase dial features polished rhodium-plated embedded scales, the result of countless trials and a very high scrap rate during production, all to achieve a level closer resemblance to the genuine product. The functions are identical to the genuine product, including calendar, day of the week, month, and moon phase, with all hidden buttons implementing true functions. The movement system utilizes the HUB1131 multi-function movement, developed over three years using imported Japanese 9015 technology, boasting powerful performance, temperature control, and power reserve. Its rounded elegance, a blend of refinement and ruggedness, makes it suitable for both formal and casual wear.
