Hublot has released the Big Bang Sapphire Sky Blue, a limited edition whose case, bezel, and caseback are all polished sapphire crystal in a pale, see-through blue. Light passes straight through the watch and hits a skeletonized manual-wind caliber built to be stared at.

The Hublot Big Bang Sapphire Sky Blue is a 44mm watch limited to 100 pieces, its bezel held by H-shaped titanium screws and its HUB1201 Meca-10 caliber good for a 10-day reserve, priced at $84,300 and sold from July 8th, at select Hublot boutiques and hublot.com.

Meca-10 has anchored this corner of the Big Bang line since 2016, an architecture Hublot's release says "challenged traditional watchmaking codes," built on the logic of Meccano construction sets. The HUB1201 spreads 223 components across an open frame and stores its energy in two parallel mainspring barrels. A rack-and-pinion mechanism sends sliding racks along an axis from 9 to 3 o'clock, and that motion forms the dual reserve display that gives the collection its face.

Hublot's sapphire program began in 2016 too, working from clear cases into colored ones. The brand now calls itself "the undisputed Master of Sapphire."

Color repeats through the layers, matte on the skeleton dial and its matching movement bridges, then in the structured rubber of the strap. Hublot promises "the boundless feeling of a summer sky." The 5+5 warranty program stretches coverage to as long as ten years.
