The Hublot Big Bang Meca-10 King Gold 45mm (Ref. 414.OI.5123.RX) is a bold expression of modern haute horology—engineered for collectors who demand mechanical artistry as much as presence on the wrist.

Crafted from Hublot’s exclusive 18K King Gold, this 45mm case delivers a warmer, richer tone than traditional rose gold, paired seamlessly with the brand’s signature industrial aesthetic. The striking skeletonized dial reveals the architectural brilliance of the in-house HUB1201 manual-wind movement, showcasing an intricate system of bridges, gears, and a linear power reserve display inspired by Meccano construction sets. 

At its core, the Meca-10 offers an extraordinary 10-day (240-hour) power reserve, a rare feat in contemporary watchmaking, allowing extended performance with minimal winding.  The sapphire crystal and exhibition caseback provide uninterrupted views of this mechanical architecture, while the robust construction ensures 100 meters of water resistance—blending luxury with real-world wearability. 

Finished with a structured rubber strap, the watch balances high horology with everyday comfort, embodying Hublot’s philosophy of “Art of Fusion”—where traditional craftsmanship meets cutting-edge design.
