HublotBig Bang Model No: 821.NX.0170.RX

Crafted in satin-finished and polished titanium, the 42mm Square Bang Unico Titanium 821.NX.0170.RX showcases Hublot’s disruptive design language in a square silhouette—an audacious departure from its round-dial predecessors. Its skeletonised dial reveals the in-house HUB1280 UNICO movement, a self-winding flyback chronograph with column wheel, delivering precision and a 72-hour power reserve.

The open architecture offers a front-row view of the calibre’s double-clutch mechanism, framed by a black composite resin bezel with six signature screws. A black structured rubber strap with a distinctive textured pattern adds ergonomic comfort and visual balance. Fitted with Hublot’s One Click system for easy strap changes and water-resistant to 100 metres, this watch fuses innovation, form, and high-end horology in a daring, geometric package.

At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
