First unveiled in 2016, Hublot's Big Bang MECA-10 is a playful watch with a movement construction like no other. Void of a conventional dial, the MECA-10 makes visible and aestheticizes something that is normally hidden. Inspired by Meccano-type construction systems, the MECA-10 is a masterclass in micromechanical engineering and a creatively intriguing spin on how we perceive mechanics and the motion of time itself.

Now, nearly a decade later, Hublot brings back the MECA-10 with an optimized calibre in a more compact 42mm case in King Gold, Titanium and Frosted Carbon.

For the 2025 edition, Hublot improves upon the MECA-10's manual-winding skeleton movement with a refined, open and coherent display, while maintaining its distinctive construction that’s elevated with refined finishing and decoration. For the engineers and watchmakers at Hublot, the challenge was to preserve all that makes the MECA-10 so original, while reducing its dimensions to fit the 42mm Big Bang case without compromising its performance.
