Monochrome Watches reported the models, specifications and launch prices on 24 November 2025; those prices are launch figures, not current quotes.
How the two Winter editions differ
| Specification | Big Bang Unico Winter Sapphire | Big Bang Unico Winter Titanium Ceramic |
|---|---|---|
| Reference | 441.JX.429B.VR | 441.NH.429B.VR |
| Case construction | Polished transparent sapphire, including the lugs, case-middle windows, caseback and dial; titanium pushers, screws and strap system | Microblasted titanium case, polar-white ceramic bezel and white ceramic shock-absorbing flank inserts; screw-down crown |
| Diameter and thickness | 42 mm; 14.5 mm | 42 mm; 14.5 mm |
| Water resistance | 50 m | 100 m |
| Edition size | 30 pieces | 200 pieces |
| Reported launch price | CHF 70,000 / EUR 80,000 | CHF 22,900 / EUR 26,200 |
All specifications and launch prices in the table were reported by Monochrome Watches in November 2025, rather than independently verified against a current Hublot listing. The price difference reflects two distinct case constructions; the editions are not different sizes or different chronograph calibres.
Winter Sapphire: the transparent case
The Winter Sapphire makes transparency its defining feature. Its polished sapphire construction extends across the lugs, case-middle windows, caseback and dial, giving a view through much of the watch rather than just through a conventional display back. Titanium is used for the pushers, screws and strap system. Monochrome reports 50 m water resistance and a limited run of 30 pieces.
Winter Titanium Ceramic: titanium with white ceramic
The Winter Titanium Ceramic uses a microblasted titanium case with a polar-white ceramic bezel and white ceramic shock-absorbing flank inserts. It has a screw-down crown and a reported 100 m water-resistance rating. Its edition is limited to 200 pieces—more than the Sapphire version, though still a limited release according to the report.

What they share: movement, dial and dimensions
HUB1280 Unico chronograph
Both watches use the HUB1280 Unico Manufacture automatic flyback chronograph, with a column wheel and a reported 72-hour power reserve. Monochrome lists 354 components, 43 jewels and a frequency of 28,800 vibrations per hour (4 Hz), and says the movement is protected by five patents.
Openworked dial and 42 mm format
Each edition measures 42 mm across and 14.5 mm thick. The openworked dial has light-blue accents and an exposed column wheel at 6 o’clock. Its indications include a 60-minute chronograph register and date at 3 o’clock, with running seconds at 9 o’clock. The matching dimensions and movement make case material, visibility and water resistance the main practical distinctions between the two models.

Straps and changing them
Monochrome reports white rubber and white calfskin straps, as well as an additional combination of white rubber and blue calfskin. The watches use Hublot’s One Click interchangeable system and a titanium deployant clasp. The report does not establish compatibility with third-party straps, so a non-Hublot strap should not be assumed to fit simply because it has a similar width or appearance.
