Luminox Navy SEAL 3503 XS.3503.F Men's Watch Black • Swiss Quartz Movement • 200 m Water-Resistant

The Luminox Navy SEAL 3503 (reference XS.3503.F) is a robust diver's watch from the iconic Navy SEAL 3500 series, a modern reinterpretation of the original Navy SEAL timepiece. The distinctive case crafted from the patented CARBONOX™ composite material measures 45 mm in diameter and is water-resistant to 200 metres, making this watch a reliable companion for demanding underwater missions. Swiss Made quality and comprehensive CO2 neutrality in accordance with Scopes 1, 2 and 3 of the Greenhouse Gas Protocol underline the ambition behind this timepiece.

The blue dial with white numerals ensures maximum legibility in daylight. In dark environments, the proven Luminox Light Technology takes over — a self-powered illumination system requiring no button press, glowing constantly for up to 25 years. Hardened mineral glass (550–650 Vickers) reliably protects against scratches, while the screw-down crown with double safety gasket guarantees the highest level of water resistance. The rubber strap provides excellent wearing comfort even during physical activities.
