Hublot Big Bang 421.NM.1170.RX Super Clone
$1,135.00
The NM microblasted steel variant of the 421 series gives a lighter profile than the all-black versions with the same skeleton dial. Microblasted steel has a tight, even satin texture that resists fingerprints better than polished surfaces. The grey steel between the black case components changes the side profile compared to the ceramic variants. This reads less aggressive than the all-black 421 versions.

Where this build differs from the original
- Movement. A cloned movement built to the architecture of the original, not a genuine factory calibre. Ask us which calibre is in the build currently in stock.
- Water resistance. The genuine reference is rated to 100 metres. This build is not pressure tested. Treat it as splash resistant and keep it out of the pool.

G. Schneider –
5 stars. This Hublot Big Bang 421.NM.1170.RX surprised me right out of the box. The sandwich case construction has real presence, and the dial visibility is excellent from every angle I’ve tried. Compared with photos of the genuine, it gets the vibe impressively close for a first-time replica buy. Highly recommend.

Arrived and opened it this morning, and I’ve got to say the case work is what sold me first. The sandwich case construction feels properly done, and side by side with my memory of the genuine, it nails the overall look better than I expected. the dial has a clean read and the watch carries itself well on wrist. My only small nitpick is that the strap needed a little settling before it felt perfect. Still, for a collector, this one is easy to recommend.
