For more than three decades, Luminox has had a working relationship with the U.S. Navy SEALs — one of the most demanding partnerships any watch brand could ask for. That connection has shaped the company's entire lineup, pushing it to build tools that can survive conditions most people will never face. The latest result of that legacy is the Luminox Navy SEAL Chronograph XS.3587, a watch that blends two distinct styles into one capable package and does it with a colorway that looks like it came straight out of a special operations briefing room.

Two Watch Styles, One Tough Case
At first glance, combining a dive watch with a chronograph sounds like the kind of idea that should stay on the drawing board. Divers are built for depth and water resistance. Chronographs are built for timing. On paper, the two seem like an odd couple. But in practice, the pairing actually opens up something useful.
Watch expert Johnny Brayson explained the appeal this way: "They're plenty functional as long as they're lumed. Plus, they give you the opportunity to time two separate events: one using the bezel, and one using the chrono."
That means the wearer gets two independent timing systems in a single watch — the rotating bezel for one task and the chronograph pushers for another. That kind of flexibility matters when time is literally the point.
Brayson also pointed out something that gets overlooked when people first hear about this combination. "It takes some impressive engineering to make [diver chronos]," he said. "Pushers are two more ways for water to get in that need to be accounted for." The XS.3587 carries a 200-meter water resistance rating, which tells you Luminox solved that problem rather than just hoping for the best.
What Luminox Means by Lume
The brand name itself is rooted in luminescence, and that philosophy runs through every watch they make. The XS.3587 is no exception. Every hand on the watch — including the subdial hands — and every hour marker features Luminox's signature self-powered lume system, rated to last 25 years without needing a battery or external light source to charge it.

That is not a small thing in a watch meant for real-world use. Whether it's a night dive, a power outage, or just checking the time during a long drive, the illumination is always on without any action required from the wearer. It works in the dark the same way it works in daylight. That consistency is part of why military operators have trusted the brand for so long.
The Coyote Tan Colorway
The XS.3587 uses what Luminox calls a tactical colorway, and the execution is clean and purposeful. The case, strap, and overall base of the watch are blacked out. The strap is rubber, and the case is made from Carbonox — Luminox's proprietary carbon-based material that manages to be both extremely tough and noticeably light on the wrist. For a 45mm watch, that weight reduction matters over a long day.
Set against that dark base are the subdials and indices, finished in coyote tan. For anyone unfamiliar with the term, coyote tan is a warm, earthy brown that has been standard-issue in military and tactical gear for years. It reads as serious without being flashy, and on this watch it provides something practical — better at-a-glance readability against the black background.
The combination does two things at once. It connects the watch visually to its military roots while also making the dial easier to read quickly. Those two goals don't always line up, but here they do.
What's Under the Hood
The movement inside the XS.3587 is a Ronda 5030.D, a Swiss-made quartz caliber. For a watch built around dependability in demanding environments, quartz makes a lot of sense. It keeps accurate time without requiring winding or the kind of servicing that mechanical movements need, and it holds up better under shock and vibration.
The crystal is mineral glass, and the caseback is 316L stainless steel — the same grade of steel used widely in professional and medical equipment for its corrosion resistance. The case itself measures 45mm, which gives the dial enough real estate to house the chronograph subdials without everything feeling cramped.
A Watch With a Reason to Exist
There is no shortage of dive watches on the market. There is also no shortage of chronographs. What is genuinely harder to find is a watch that handles both functions competently, especially at this price point and with this level of proven durability behind it.

The XS.3587 is not a watch that was designed to look tactical. It was designed to be useful in the same conditions that shaped the brand's entire history. The colorway is a nod to that history, but the engineering is what backs it up.
Price and Where to Get It
The Luminox Navy SEAL Chronograph XS.3587 is available now through Luminox's official website at $845. For a Swiss-made, military-grade timepiece rated to 200 meters with a dual timing system and a 25-year lume solution built in, that price lands in reasonable territory for what the watch actually delivers.
