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
】V2 upgraded version Blancpain BLANCPAIN Fifty Fathoms “Dark Side of the Moon” 5015-11C30-52 Ultimate Edition, 45mm diameter, bezel edge and mirror made of scratch-resistant sapphire crystal material, equipped with imported RE automatic mechanical movement. Specific details are as follows:
1. Corrected the specifications and shape of spring bars (100% compatible with the original).
2. Refine the case assembly details to match the quality of the genuine product and improve the texture of the watch head.
3. Improved the luminous effect by enlarging the luminous portion of the four Arabic numerals and reducing the size of the metal edging to match the original design and enhance the luminous effect.
4. Corrected the issue of reflection and ghosting on the glass in the existing version on the market. After the correction, when viewed from the side, the violet coating effect is clearly visible at the edge of the glass, restoring the craftsmanship of the genuine product!
ZF Factory masterpiece of craftsmanship. Welcome all experts to appreciate!
