Bulova 98B465 Marine Star Automatic Black Dial Rubber Strap

Bulova 98B465: The Marine Star Gets Serious

The Marine Star has been in Bulova’s lineup for years, but the Series B redesign is where things get interesting. The 98B465 takes the collection from “sport-adjacent” to genuine diver territory—200m water resistance, a unidirectional bezel with bi-color aluminum insert, screw-down crown, and an anti-reflective sapphire crystal. At 41mm, it wears right in that modern sweet spot where it’s substantial enough to look like a real tool watch without overtaking your wrist.

The Dial That Shifts

Bulova calls it a fume dial, and it delivers. The sunray finish transitions from a lighter center to dark edges, giving the face more depth than a flat black dial would. Luminous hands and hour markers are generously applied—legibility underwater isn’t an afterthought here. The date window at 3 o’clock is clean and unobtrusive, which is harder to get right than it sounds.

What’s Running It

Inside is the Miyota 8215, a workhorse automatic that’s been proving itself across the industry for decades. It’s not flashy—no hacking, no hand-winding—but it’s reliable, accurate enough for daily wear, and easy to service. The 42-hour power reserve means you can take it off Friday night and pick it up Monday morning without resetting. The exhibition caseback lets you watch it work, which is a nice touch at this price.

Built for the Water

The 200m water resistance with a screw-down crown means this is rated for actual swimming and snorkeling, not just rain. The HNBR rubber strap is a smart choice for a diver—it handles saltwater and chlorine without complaint, and the wave-textured pattern on the underside adds grip without bulk. The 20mm lug width also means strap swaps are easy if rubber isn’t your thing.

The Bottom Line

The 98B465 is Bulova making a case that you don’t need to spend four figures for a well-equipped automatic diver. Sapphire crystal, 200m rating, exhibition back, and a proven movement—it checks the boxes that matter. If you want a capable diver that looks good enough for dinner afterward, this is a smart buy.
