Limited to 100 pieces, the 44mm timepiece features a clear multi-piece sapphire case, a matching [sky-blue rubber strap](https://www.trendhunter.com/trends/piaget-altiplano-ultimate-automatic) with a one-touch quick-release system and a skeleton dial that reveals the mechanical architecture beneath. Blue movement bridges become a defining visual element, shifting the emphasis from the case to the exposed mechanics. Powering the watch is the in-house HUB1201 Meca-10 caliber, a 223-component movement equipped with twin mainspring barrels that deliver a [10-day power reserve](https://www.trendhunter.com/trends/hublot-mp17-meca10). The movement incorporates a rack-and-pinion power reserve display while remaining fully visible through the transparent case. Continuing Hublot's long-running exploration of sapphire materials and exposed mechanics. The Hublot Big Bang Sapphire Sky Blue is priced at $84,300 and was released in July as a limited edition of 100 pieces.
