At 42mm, this Hublot Big Bang is housed in black ceramic adorned with diamonds, extending the same diamond-set treatment to the bezel for a cohesive, dramatic aesthetic. A sapphire crystal protects the dial, while the screw-locked crown and 100-metre water resistance add a layer of everyday practicality to the watch's striking presence.
The black skeleton dial reveals the automatic movement beneath, with luminescent index markers and luminescent hands ensuring legibility in low-light conditions. The open architecture of the dial gives the piece a technical, architectural character that is central to the Big Bang identity.
A leather strap secured by a folding clasp completes the watch, offering a refined contrast to the ceramic and diamond case. Reference 642.CI.0110.RX.1700 represents the Big Bang line's signature blend of bold materials and mechanical transparency.
