Luminox Navy SEAL 3550

A fresh interpretation of one of Luminox's best-known tactical watches, the Navy SEAL XS.3553 combines the rugged construction of the 3550 Series with a deep blue dial and matching blue rubber strap. The lightweight 44mm CARBONOX™ case is paired with a unidirectional rotating bezel, protected screw-down crown and anti-reflective sapphire crystal. Bold white markings provide excellent contrast against the blue dial, while the numerals use Liberator Sans Heavy — the official font of the U.S. Navy and a subtle reference to the collection's military heritage. Inside is a dependable Swiss Ronda 515 quartz movement, providing straightforward time and date functionality. Sixteen Luminox Light Technology tubes deliver constant self-powered illumination for up to 25 years, allowing the watch to remain visible in darkness without needing to be charged by an external light source. With 200 metres of water resistance, a blue nitrile rubber strap and a weight of only 71g, the XS.3553 combines genuine performance credentials with a slightly more colourful, everyday character than Luminox's traditional all-black tactical watches.
