Bulova 98B466 Marine Star Automatic Blue Dial Bracelet

Bulova 98B466: The Marine Star Gets Serious

The Bulova 98B466 Marine Star Series B is a ground-up redesign of one of Bulova’s most recognized sport watches. This isn’t a facelift—it’s a rethink. At 41mm with 200 meters of water resistance, a sapphire crystal, and an automatic movement, the new Marine Star checks boxes that the previous generation didn’t. Bulova clearly paid attention to what the competition is doing in this price range and responded accordingly.

The Dial That Earns a Second Look

The blue-to-black gradient sunray dial is the first thing you notice, and it’s well-executed. It shifts from a vivid blue at center to black at the edges, mimicking ocean depth in a way that’s more subtle than gimmicky. Luminous hands and hour markers are bold and legible—Bulova didn’t skimp on the lume. A date window sits at 3 o’clock, cleanly integrated without disrupting the dial layout. The unidirectional bezel features a bi-color aluminum insert in blue and black that complements the dial without matching it exactly, which is the right call.

What’s Inside: Miyota Cal. 8215

The Miyota 8215 automatic is a proven workhorse—reliable, affordable to service, and good for 42 hours of power reserve. It’s not a chronometer, but at this price point nobody’s expecting one. The exhibition caseback lets you watch the rotor spin, which is a nice touch on a sport watch that could easily have gotten away with a solid back. The movement hacks and hand-winds, giving you the basics you need for daily wear.

Built for the Water

The 41mm stainless steel case hits the sweet spot for a modern dive watch—substantial without being oversized. You get a screw-down crown, 200m water resistance, and an anti-reflective sapphire crystal that handles underwater legibility and daily abuse equally well. The H-link bracelet is a step up from what you typically see at this price, with a fold-over safety clasp and 20mm lug width for easy strap changes if that’s your thing.

The Bottom Line

The Marine Star Series B is Bulova proving they can compete in the mid-range automatic diver space. If you want 200m water resistance, sapphire, and an automatic movement without spending Seiko Prospex money, this is a strong option. The blue gradient dial gives it personality, and the 41mm sizing means it wears well on most wrists.
