Citizen Promaster BN0150-28E Review
A Legendary Solar Diver That’s Tough as Nails (And Then Some)
It’s kind of funny that I even stopped to write a full review of this watch. I’ve owned it for a long time — since 2016, actually — and it’s shown up on almost every “best of” list I’ve ever written. It’s always been in the background doing its job, a watch I grab without thinking, and because of that, I never gave it the spotlight it deserves. So let’s rectify that. The Citizen Promaster BN0150-28E is a worthy watch, deserving of the limelight, and if there’s ever been a time to give this thing a proper review, it’s now.
The Classic Diver Energy

There’s something timeless about this watch’s design. It’s not flashy, it’s not trying to be something it’s not. It’s utilitarian in the best way. This is a watch that wants to be used. In fact, the BN0150-28E is so often referred to as a “gateway drug” into the world of watches — and that’s because it nails the basics while still offering tech and heritage you can respect.
Released in 1985, the Promaster name has always been Citizen’s answer to professional-grade adventure watches. And this particular reference, with its Eco-Drive movement, remains one of the most compelling offerings under $300. No winding. No battery changes. Just wear it in the sun once in a while and you’re good to go.
Case Dimensions and Wrist Presence

Specs on paper? 44mm case, 11.5mm thick, and 200m water resistance. But don’t panic — the short lugs and compact profile help it wear like a 41mm on most wrists. I’ve worn this thing on sweaty hikes, bike rides, and beach days, and it always feels comfortable, never bulky.
You get a screw-down crown at 4 o’clock, chunky knurled bezel, and fully brushed marine-grade stainless steel construction that’s taken all the dings and dents I’ve thrown at it without flinching.
Dial and Legibility

Under a clear mineral crystal (with solid anti-reflective coating), the dial is textbook tool diver. Oversized markers, trapezoidal cardinal indices, and hands with enough lume to light up a room at 2 AM. I’ve woken up for a glass of water and the thing is still glowing like a torch on my nightstand. I’ve read reviews where professional divers say it glows so brightly it messes with your eyes during night dives — that’s not an exaggeration.
The date window sits between 4 and 5, nicely aligned with the crown. The glossy black dial is sharp, but doesn’t distract. It’s a clean, legible setup that punches way above its price.
That Eco-Drive Movement

Let’s talk about what makes this watch a no-brainer: Citizen’s Eco-Drive technology. It’s not just solar — it charges off any light source, even the dim junk from your computer monitor. I’ve never had to do a single thing to keep it running in 8+ years.
And here’s the kicker: the power reserve is nuts. Get it fully charged and you’ll get up to 6 months of run time. So yeah, unless you throw it in a drawer for half a year, it’s always ready to go. No battery swaps, no maintenance, no surprises.
Strap Thoughts (Because Let’s Be Honest…)

Let’s not sugarcoat it — the stock rubber strap is serviceable at best. It’s thick, stiff, and takes forever to break in. I wore it for about a week before switching it out.
Mine has lived on a gray Ritchie silicone strap for years. It’s more comfortable, fits the case better, and doesn’t cheapen the overall experience. I’ve also tried it on a few NATOs, and I’ll be honest — it’s not a great look. Something about the chunky case and curved lugs just doesn’t play well with nylon. It always looks top-heavy.
Eventually, I grabbed one of Long Island Watch’s stainless steel bracelets, and that was a game-changer. It brought a more substantial, balanced feel to the whole package. The downside? Still no on-the-fly micro-adjustment, and for the life of me, I don’t know why brands keep dropping the ball on this. If microbrands can offer a solid clasp with fine adjustment for $300, there’s no excuse.
Final Thoughts

Look — this isn’t the prettiest diver on the planet. But it’s one of the best. It’s rugged, solar-powered, reliable as hell, and priced right. If you need a tool watch that won’t quit, the Citizen Promaster BN0150-28E is it. You don’t baby it, you just wear it.
You get real-world durability, impressive specs, and a heritage brand that has quietly built one of the most practical dive watches on the market. The fact that I’ve owned both the black and blue dial versions, and still wear them both, says everything.
Should you buy one?
Absolutely.
It’s not just a great entry-level diver. It’s a long-haul companion — a true classic.
