Luminox Master Carbon SEAL 45mm Blue Dial Rubber Mens Automatic Watch XS.3863

The Luminox Master Carbon SEAL Automatic XS.3863 is a 45mm Swiss Made dive watch with a CARBONOX™+ case measuring 14mm in thickness. The case is paired with a blue dial, a black IP-plated 316L stainless steel unidirectional rotating bezel and a sapphire crystal with anti-reflective coating. Water resistance is rated to 200 metres, while the screw-down crown has crown protection and a double-gasket construction.

Day-Date Display

The blue dial combines the main time display with day and date indications, giving the watch an additional practical function. Luminox Light Technology uses self-powered micro tritium gas tubes to provide continuous illumination for up to 25 years, allowing the hands and markers to remain visible in low-light and dark conditions without relying on an external light source.

CARBONOX™+ Case

The case is made from Luminox’s CARBONOX™+ material, a carbon-fibre-reinforced polymer developed by the brand. Luminox describes the material as strong and lightweight, while the official specifications give the complete watch a weight of 110g. The see-through case back is made from 316L stainless steel and allows the automatic movement and rotor to be viewed.

Swiss Automatic Movement

Powering the XS.3863 is the Swiss Made SELLITA SW 220-1 automatic movement, which operates the time and day-date functions. The movement has a power reserve of approximately 38 hours and is wound automatically through the movement of the wrist. The exhibition case back provides a view of the mechanical movement in operation.

Blue Nitrile Rubber Strap

The watch is fitted with a blue nitrile rubber strap measuring 24mm at the lugs and secured with a 316L stainless steel buckle. The strap complements the blue dial, while the black bezel and CARBONOX™+ case maintain the watch’s functional dive-watch design. The combination of 200-metre water resistance, a unidirectional rotating bezel and Luminox Light Technology supports its use in demanding outdoor and underwater environments.
