Hublot Big Bang 441.NL.5171.RX Super Clone
$1,110.00
The 441 is a distinct case generation from the 421, and the differences show at the lugs. The NL case material has a surface character not shared by other Big Bang variants in the range. The 5171 dial reads as a lighter face inside the darker case boundary. Check the six H-shaped screws as with any Big Bang, then check the rubber-to-lug contact where the 441 geometry differs from older series.

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.
Every watch spends 24 to 48 hours on a timegrapher before dispatch, and you approve photographs and video of your actual watch before it ships. Two year warranty, in writing. More on what a super clone is, or see the rest of the range.

Bought this watch after seeing it online, and it turned into my new everyday piece for yard work, errands, and supper out. The integrated bezel screws are the part I notice most, because they give it that bold Big Bang look without trying too hard. it wears better than I expected. My only small gripe is the strap took a day or two to settle in. Still, I’d recommend it.

Compared side by side with the genuine 441.NL.5171.RX, this Hublot Clone does a lot right. The integrated bezel screws sit where they should and give the watch that proper Big Bang look, not a cheap afterthought. On the wrist it has the right presence and the finishing reads well at normal viewing distance. For me, the biggest win is how close it feels overall to the real thing, especially in profile. I gave it as a gift, and the reaction was instant excitement.
