45 mm Carbonox Dive Watch

This Luminox 3863 is a Swiss-made automatic dive watch built for men who need a rugged, legible timepiece for water sports and daily wear. Its Carbonox case and sapphire crystal with anti-reflection coating resist corrosion and scratches while the blue dial and rubber strap deliver a cohesive aquatic look. Night-vision tubes on the hands and markers provide continuous low-light readability without an external light source.

Suited for professional divers and active users

The 200 m water resistance, unidirectional rotating bezel and screw-down crown meet ISO-style dive requirements, making it reliable for serious underwater use. Buyers who want a slimmer profile under a dress cuff or a lighter titanium construction should consider other models. The fixed 45 mm case diameter also limits appeal for smaller wrists.

200 m water resistance decides the fit

A 200 m rating with a double-security gasket crown and screw-on steel caseback qualifies the watch for recreational scuba diving and high-velocity water sports. If your needs stop at swimming or snorkelling, a lower-rated watch will suffice; if you plan saturation or mixed-gas diving, you need a dedicated helium-escape model.

Questions about this item

How deep can the 3863 go before water resistance fails?

The watch is rated to 200 metres (660 feet), so it stays sealed for recreational diving and heavy surface use.

Does the automatic rotor or Carbonox case become noticeably warm or loud during all-day wear?

The Swiss automatic movement runs silently and the Carbonox case stays at skin temperature; no audible rotor noise or heat build-up occurs.

What strap width or tools are needed to fit the blue rubber band on the 45 mm case?

The integrated rubber strap attaches with spring bars; a standard spring-bar tool lets you swap or resize it without extra parts.
