The Hublot Spirit of Big Bang Moonphase Titanium Skeleton, reference 647.NX.1137.RX, is a striking example of avant-garde design and technical sophistication. Crafted from lightweight and durable titanium, the 42mm tonneau-shaped case delivers a bold wrist presence while maintaining exceptional comfort.

This model showcases Hublot’s signature fusion of materials and aesthetics, with a blend of satin-finished surfaces and polished edges that enhance its modern, industrial appeal. The dial is framed by a fixed titanium bezel secured with Hublot’s trademark H-shaped screws, adding to the watch’s technical character. Fitted with a black structured rubber strap and deployant clasp, it offers a perfect balance between high-end luxury and everyday wearability.
Powered by the in-house HUB1770 automatic skeleton movement, the Spirit of Big Bang Moonphase delivers both visual impact and mechanical precision. Offered with its original box and papers, this timepiece is a compelling addition for collectors and enthusiasts seeking a distinctive, open-worked watch with a contemporary edge and full provenance.
