Monochrome's 2025 hands-on gives 10.8mm "with crystal" (recorded; the brand's 10.5mm doesn't say whether the crystal is included) and adds: brushed and polished case, bidirectional 48-click bezel with black ceramic 24-hour insert, AR-coated sapphire, solid caseback held by four screws with the serial number of the turbine steel used, signed screw-down crown with minimal guards, white Super-LumiNova, 20mm seven-link brushed and polished bracelet with signed folding clasp and twin pushers, movement adjusted in a sixth position after casing, EUR 2,400. The GMT hand is set independently in one-hour steps (office GMT); the movement's date isn't used (no date window). The product page is still under the current collection but sold out ("Disponibile su richiesta", available on request). The brand's terms of sale say prices include IVA (Italian VAT).
