Housed in a 44mm round black ceramic case, this Big Bang Unico Black Magic features a fixed black ceramic bezel and a screw-down crown. The transparent case back reveals the mechanics within, while scratch-resistant sapphire crystal protects the silver skeleton center dial — adorned with luminescent silver-tone hands and alternating index and Arabic numeral hour markers, plus Arabic numeral minute markers at five-minute intervals and additional markers around the outer rim.
Powering the watch is the Hublot calibre HUB1280 automatic movement, a 43-jewel, 354-part architecture beating at 28,800 vph with a power reserve of approximately 72 hours. Chronograph functionality is delivered via a column wheel mechanism, with two sub-dials tracking 60 minutes and 60 seconds respectively. Water resistance is rated to 100 meters / 330 feet.
The watch is presented on a black rubber strap fastened with a deployment clasp, and is accompanied by its original box and papers. Reference 421.CI.1170.RX carries the Swiss Made designation, placing it firmly within Hublot's celebrated Big Bang collection.
