Description
Luminox Navy SEAL Chronograph 45mm – 3580 Series Military Watch (XS.3581.BO)
Built for tough conditions and low-light missions. The Luminox Navy SEAL Chronograph from the 3580 Series combines a durable 45 mm CARBONOX™ case with a unidirectional rotating diver’s bezel and 200 m / 20 ATM water resistance, making it suitable for demanding duty use and diving.
The modern black-on-black dial is equipped with Luminox Light Technology (LLT) for constant visibility without charging or button activation. The lighting system is designed to glow for up to 25 years (visibility depends on conditions and individual eyesight).
Powered by a Swiss quartz movement (RONDA 5030.D), the watch delivers reliable chronograph timing with a date function. A double seal and crown protection support durability and resistance in wet or harsh environments.

Manuals
Navy SEAL Series
Beginning in 1992, Navy SEALs procurement officer Chief Nick North was tasked with finding a watch that could “cut through the darkness” and withstand brutal operational conditions. His search led to Luminox, establishing a long-standing association with elite forces and night-oriented performance requirements.
Luminox Light Technology (LLT)
LLT uses tiny self-powered illumination tubes designed to provide 24/7 visibility without external charging. Unlike painted lume that fades quickly or push-to-light systems, LLT supports consistent readability in low-light conditions for extended service life.
