Hublot Big Bang 421.NX.1170.RX 44 mm Black Dial

The 421.NX.1170.RX presents the Big Bang Unico in its most elemental titanium form. A 44 mm titanium case and matching titanium bezel are finished with a mix of polished and satin surfaces, while the black rubber strap keeps the watch visually anchored. The sapphire crystal carries anti-reflective treatment, and the satin dial leaves the chronograph hardware and case construction to provide the visual rhythm. With luminous details and 100 metres of water resistance, its large format remains functional as well as assertive.

The automatic HUB1280 supplies the technical depth. Its in-house architecture uses a column-wheel chronograph with flyback capability and a date display, backed by a 72-hour power reserve. The movement has 43 jewels, 354 parts, and a full rotor. Set against the monochrome case and strap, that calibre makes the 421.NX.1170.RX a clear expression of the Unico formula rather than a decorative variation.
