Navy SEAL “SEMPER-FORTIS” Limited Edition XS.3515.N

Semper Fortis is Latin for "Ever Strong" — a phrase long associated with the U.S. Navy and the perseverance, discipline and quiet determination expected of those who serve.

The stealth-inspired black dial carries the collection's defining detail. Between the eight and eleven o'clock positions, the words “SEMPER-FORTIS” are coated in Super-LumiNova®, while the English translation, EVER STRONG, appears directly beneath in red. During daylight, the translation provides a subtle reminder of the watch's inspiration. As ambient light fades, the glowing Latin phrase gradually takes prominence, revealing a message that reflects the resilience of the elite forces this watch represents.

The symbolic design is matched the technical performance expected from a Luminox timepiece. Swiss Made and equipped with a screw-down crown to support it’s 200 metres of water resistance and Luminox Light Technology for constant visibility in any light condition for up to 25 years, it remains purpose-built for those who demand dependable performance.

Built around the proven 45mm Navy SEAL 3500 series, the watch retains the collection's distinctive turtle-shaped case while becoming one of the most comprehensive applications of CARBONOX in the Luminox collection. The lightweight yet highly durable material extends beyond the case to the unidirectional rotating bezel and bracelet, creating a fully integrated construction designed to withstand demanding conditions while remaining extremely lightweight and comfortable for everyday wear.

"By allowing “SEMPER-FORTIS” to emerge as light fades, we created a design that reflects the quiet resilience and determination of the people the phrase has represented for generations" explains Pierrick Marcoux, Group Product Director at Luminox.

Limited to 775 individually numbered pieces worldwide, the edition pays tribute to 1775, the year the U.S. Navy was established. The production number serves as a quiet acknowledgment of a legacy built on commitment, endurance and service.
