Between my closet and the bedroom door there’s about two steps of floor, and that’s where I make every small purchase decision of the day. Wear it a lot enough, keep it simple, and it earns a place. That’s the test almost everything has to pass.
A $84,300 watch lands on that floor one day and the test gets a lot more interesting.
Full disclosure: it never leaves my desk. This is not the watch I want to live in. It’s the one I study. And after a while studying it, I’ve grown genuinely fond of the way Hublot built the Big Bang Sapphire Sky Blue. No, the dial. Almost none.
What’s actually in the case
The case is clear sapphire, 44 mm, and it puts the whole multi-piece Big Bang structure on display. No dial gets in the way of the watch. Under the glass sits Hublot’s HUB1201 Meca-10, a manually wound movement with 223 components, and it’s finished in matte sky blue. The bridges, the architecture, the works. That’s the color. The case stays transparent so you see everything, and the color story is the movement itself instead of a painted face.
The strap is structured sky-blue rubber, and it’s on a quick-release system. You swap straps without tools, one button, done. I appreciate that. A watch that respects the fact that my life involves rain and hands that need to be free.
The math that earns the price
Two mainspring barrels run in parallel, which is how you get a 10-day power reserve on a manual. Wind it, then go a full work week and a left. The rack-and-pinion system behind it powers the dual power-reserve display, and that’s the piece of engineering you’re really looking at when you look at the watch. Two days off and time reappearing on the two displays is a genuinely good party trick for a wrist-sized clock.
It’s limited to 100 pieces globally, and it went out in July for $84,300. Not a number for my paycheck. I’m not pretending it is.
What the color gets right
Color is back in the watch world. Rolex pushed a multicolored Oyster Perpetual 36, the Audemars Piguet and Swatch collab has had its moment, and Hublot has spent the past 10 years putting color into sapphire cases. Nearly every other Meca-10 has stayed in black, gray, and gold, which reads closer to brutalist than to anything else. So a sky-blue version lands with actual contrast.
Hublot also has a Big Bang Unico Water Blue Sapphire out in the current lineup, and it does the opposite: a pale blue-tinted case with a silver movement inside. This one flips the relationship. Clear case, colored works. Same family, opposite move, and I think the inverted version is the more confident one.
Sapphire cases and exposed Meca-10 architecture both dated to Hublot in 2016, so this watch is two decade-old threads tied into one piece. The clear case does the showing, the blue dial and bridges do the talking. Neither is hiding behind the other.
Style Math
$84,300 ÷ 10 wears a year = $8,430 a single wear. That’s not cost-per-wear, that’s cost-per-occasional-stare. Do the math on a piece like this and realize most of you, including me, should admire it from a safe and honest distance. The 10-day reserve is the one detail that reads as investment-grade: a watch that doesn’t need babysitting.
FAQ
Is the dial a separate color layer?
The dial is part of the skeleton and it’s finished in matte sky blue. There’s no painted record there. The bridges underneath match, and the case stays clear, so the whole piece reads as one color story.
Can I swap the strap without tools?
Yes. It’s on Hublot’s quick-release system. One button, strap comes off, strap goes on. No tool kit needed.
Is this a daily driver?
I’d say no, and say it kindly. 100 pieces, clear sapphire, and that price put it in the collection-first category. Daily drivers earn their keep in rotation, this one earns its keep on the wrist on the rare, chosen day.
A note from Lena
I used to buy the trend first and ask questions later. This was one of the pieces that made me stop and do the cost-per-wear math before the wanting shut up. It’s not for me. I probably won’t own it. But I’d love to see it on someone, exactly once, and then let it keep living in a case in another city. Not every piece has to be yours to be worth your attention. Sometimes the honest move is to look, finish looking, and walk away with a better eye.
