Crafted entirely in white ceramic — from the 42 mm round case to the fixed bezel and matching bracelet — this Big Bang Integral Chronograph carries reference 451.HX.1123.HX. The case measures 14.5 mm thick and features a screw-down crown, a transparent caseback, and scratch-resistant sapphire crystal, with water resistance to 100 meters / 330 feet. A deployment clasp secures the ceramic bracelet at the wrist.
The skeleton-center dial is finished in mat grey and fitted with luminous silver-tone hands alongside index hour markers and Arabic numeral minute markers at five-minute intervals around the outer rim. Two sub-dials track elapsed 60-minute and 60-second chronograph intervals, while a date display sits between the 4 and 5 o'clock positions — together covering the full suite of hour, minute, second, date, and chronograph functions.
Powering the watch is the Hublot calibre HUB1280 automatic movement, composed of 354 parts set with 43 jewels, beating at 28,800 vph and delivering a power reserve of approximately 72 hours. This timepiece is accompanied by its original box and papers and carries the Swiss Made designation.
