Hublot Big Bang Sapphire Sky Blue Meca-10: A Fresh Take on Crystal Innovation
Hublot Pushes Sapphire Crystal Boundaries with New Sky Blue Edition
Hublot has unveiled the Big Bang Sapphire Sky Blue Meca-10, a limited-edition timepiece that showcases the Swiss manufacturer's mastery of sapphire crystal machining. Released in July 2026, this watch introduces a fresh sky-blue hue to the Meca-10 lineup, marking another milestone in Hublot's ongoing exploration of transparent watchmaking.
Sapphire Crystal Case: Technical Mastery
Very few brands can create and machine sapphire like Hublot does. Since first unveiling its sapphire Big Bang in 2016, the Maison has continuously pushed the boundaries of what's possible with this extremely hard material. The new Sky Blue edition comes in a fully polished 44mm sapphire crystal case, water-resistant to 50 metres, with Hublot's signature H-shaped titanium screws securing the bezel.
The transparent construction allows an unobstructed view of the skeletonized dial and movement, while a matching sky-blue rubber strap and matte sky-blue skeleton dial complete the cohesive aesthetic.

The Meca-10 Movement
The calibre HUB1201, first introduced in 2016, features a fully skeletonised, Meccano-inspired design with twin parallel mainspring barrels delivering an impressive 10-day power reserve. Hublot's clever rack-and-pinion mechanism creates the signature dual power-reserve display, with a red indicator at 3 o'clock warning when the movement reaches its final two days of power.
Sapphire Crystal in Modern Watchmaking
Sapphire crystal has become a defining material in haute horlogerie. With a Mohs hardness of 9 (second only to diamond), it offers exceptional scratch resistance while providing unparalleled transparency. Hublot's expertise in machining colored sapphire — including orange, green, blue, and now sky-blue variants — has set them apart in this specialized field.
Frequently Asked Questions
What makes sapphire crystal so special for watch cases?
Sapphire crystal scores 9 on the Mohs hardness scale, making it virtually scratch-proof. It's also completely transparent, allowing clear views of the movement. However, it's extremely difficult and expensive to machine, which is why few brands attempt full sapphire cases.
How does the Meca-10 achieve a 10-day power reserve?
The HUB1201 calibre uses twin mainspring barrels mounted in parallel, combined with an optimized gear train, to deliver 240 hours of power from a single manual winding.
Is the Hublot Big Bang Sapphire Sky Blue a limited edition?
Yes, it is limited to just 100 pieces worldwide, available through Hublot authorized retailers and their online boutique.
