Luminox XS.3551.BO Navy SEAL 3550 Military Dive Watch 44mm in Blackout

The Luminox XS.3551.BO Navy SEAL 3550 military dive watch in Blackout combines a lightweight CARBONOX case, 200 m water resistance and 16 Luminox Light Technology tubes for visibility across changing light conditions. Swiss RONDA 515 quartz timekeeping provides time and date functions, while a sapphire crystal with antireflective coating and a protected screw-down crown support its demanding-environment design. An integrated black NBR rubber strap complements the ergonomic profile for comfortable wear. Black numerals and naval-inspired typography complete the distinctive tactical look.

Key Features

Lightweight CARBONOX Construction

The slimmer, ergonomic 44 mm design brings the established tactical-watch concept into a comfortable format for the wrist. CARBONOX forms both the case and the uni-directional rotating bezel, pairing the collection's durability focus with low-weight construction.

Integrated Black NBR Rubber Strap

Comfort is built into the integrated black NBR rubber strap, which works with the watch's ergonomic shape. A CARBONOX signature buckle carries the case material through to the closure for a coordinated design.

Protected Construction and 200 m Water Resistance

A guarded, IP black stainless steel screw-down crown and a screw-on 316L stainless steel case back support the watch's demanding-environment construction. Antireflective treatment on the sapphire crystal helps reduce reflections when checking the dial. Water resistance is rated at 200 m / 660 ft / 20 ATM.

Blackout Dial With Naval-Inspired Typography

Black numerals keep the face true to the Blackout finish, with the black strap continuing the look around the wrist. The Liberator Sans Heavy typeface is the U.S. Navy's official font, a detail that connects the dial to Luminox's decades of collaboration with the U.S. Navy SEALs.

Swiss RONDA 515 Time and Date

The RONDA 515 quartz movement keeps the focus on the essentials: time and date. Swiss Made origin and a stated 60-month battery life complement the collection's emphasis on reliable timekeeping.

16 Light Technology Tubes for Continuous Visibility

As ambient light changes, 16 Luminox Light Technology tubes maintain a constant glow to help keep the time visible. Illumination is rated for up to 25 years; that figure describes the light technology, not the watch battery.
