Gunmetal, DLC, and the Case Against Babying a Watch

If you’re a watch collector, you’ve probably flirted with the idea of a black watch. At some point, the monochrome seduction gets you. A black case on a matching bracelet has a severity to it—stealthy, self-contained, faintly militant. I’ve fallen for it more than once. I’ve owned some genuinely beautiful black watches.

I no longer own any of them.

Such is life in the fever swamp of watch addiction, where flipping is not a behavior but a temperament. Watches arrive. Watches depart. Attachments form briefly and dissolve without ceremony.

Take me back to around 2012. I owned two PVD-coated Seiko kinetic divers: the SUN007 and the SKA427P1. They were handsome, purposeful, and—contrary to every online hand-wringing session about coatings—remarkably resilient. I never scratched them. Not once. And yet they’re gone, casualties of some forgotten bout of restless dissatisfaction.

Here’s the dangerous part: you can still find them brand new on eBay. I know this because I went looking. The prices are tempting. I felt the familiar tightening in the chest as I typed the model numbers. Relapse always begins with “just checking.”

Another repeat offender from my past was the Citizen Promaster Sky BY0084-56E. I owned that watch no fewer than seven times over a decade. That’s not ownership—that’s a custody arrangement. Unlike PVD, the Citizen used Super Titanium treated with Duratect—often described as DLC. Marketing aside, the material difference is real. Stainless steel sits around 200 on the Vickers hardness scale. DLC-coated Super Titanium pushes north of 1,000. That’s not invincible, but it’s not cosplay either.

In real life, that translates to this: the clasp will show desk-diver scuffs, because clasps always do. The rest of the watch? It shrugs off normal wear with indifference.

Which brings me to the present. In a couple of days, the Citizen Super Titanium Gunmetal Diver NB6025-59H will return to my collection. Its DLC coating reads more dark gray than true black—an advantage, frankly. I plan to take it traveling. Miami. Hawaii. Heat. Salt water. Airport bins. Sunscreen. Sweat. This watch is not entering witness protection. It’s not being boxed, babied, or preserved for a future auction. It’s being worn.

I’m glad to have one black—or gunmetal—watch in the rotation. It’s a welcome disruption from stainless steel, a visual reset. But there’s a caveat worth stating. Black watches are all about proximity. Up close, the details are rich and seductive. From a distance, they collapse into silhouette—lume floating in darkness. If you need your watch to announce itself across a room, black may frustrate you.

For me, that quiet severity is the point.
