At the heart of this timepiece sits the Hublot calibre HUB1280, an automatic movement comprising 354 parts and 43 jewels, oscillating at 28,800 vph and delivering a power reserve of approximately 72 hours. A transparent case back allows an unobstructed view of the mechanism, while a screw-down crown and water resistance to 100 metres / 330 feet underscore the watch's functional credentials.
The skeleton dial forgoes a traditional surface in favour of an open architecture, framed by luminescent silver-tone hands and Arabic numeral hour markers. Chronograph functionality is distributed across two sub-dials tracking 60 minutes and 60 seconds respectively, with a date display positioned at 3 o'clock and a column-wheel mechanism governing the chronograph. Scratch-resistant sapphire crystal protects the view from above.
Worn on a black rubber strap fastened by a deployment clasp with push-button release, this Big Bang Chronograph is presented complete with its original box, international warranty card, and manual. Reference 421.NM.1170.RX is Swiss Made and classified as a men's luxury watch.
