The Bulova Marine Star has long occupied a specific niche in the watch world. For years, it was the go-to recommendation for enthusiasts seeking an bold, nautical aesthetic that did not require the steep investment of a Swiss luxury diver.
However, earlier iterations were often criticized by purists for their imposing case sizes and the frequent use of mineral crystals. With the launch of the Marine Star Series B, Bulova appears to be listening to the market. By refining the proportions and upgrading the material specifications, the brand is positioning this collection as a more serious contender in the competitive mid-range automatic segment.
Refining a Classic: The Shift to 41mm
The most significant update to the Series B is the move toward a 41mm case diameter. In previous generations, Marine Star models frequently pushed 43mm or 45mm, catering to a trend for oversized sports watches. The reduction to 41mm represents a strategic pivot toward a “sweet spot” that suits a much wider range of wrist sizes. This change reflects a broader industry trend where even dive-inspired watches are returning to more classic, versatile dimensions.
While the 41mm diameter is the headline, the overall ergonomics benefit from a 20mm lug width. This is a very good thing, since maybe you like the black dial which only comes on a rubber strap. You don’t have to worry since you will be able to easily swap it for an OEM/after market 20mm bracelet.
For the other colour variants, the stainless steel case is paired with a premium H-link bracelet, a choice that adds a touch of modern architectural flair
Under the Hood: The Automatic Workhorse
Behind the exhibition case back lies the Miyota 8215 automatic movement. As a member of the Citizen Group, Bulova’s use of a Miyota caliber is expected, but the choice of the 8215 series is an interesting one for a watch in this price tier.
The Marine Star Series B enters a crowded field. To understand its value, one must look at how it stacks up against the titans of the affordable diver market.
The primary competition amongst big brands for the Series B comes from the Seiko 5 Sports line and the Orient Kamasu. Seiko offers immense brand recognition and a vast array of colors, but many of their entry-level models still lack the 200m water resistance and sapphire crystals found in the Series B.
Orient’s Kamasu is perhaps the closest rival, offering similar specs for a slightly lower price, but Bulova’s finishing and the unique H-link bracelet design offer a more “luxury-adjacent” feel that some buyers may prefer for a daily office watch.
Pricing, Availability & Where to Get One
The Series B sits comfortably in the $495 to $595 range depending on the variant. At this price, Bulova is competing not just on specs, but on style. The Series B feels less like a “tool” and more like a “lifestyle” diver, a watch that looks just as appropriate under a shirt cuff as it does on a boat deck.
For now, it looks like it can only be acquired in the US market.

Who is the Series B For?
The Bulova Marine Star Series B is a successful evolution of a fan favorite. It successfully bridges the gap between the brand’s fashion-forward history and the demands of the modern watch community.
Who should consider this watch? It is an excellent choice for the buyer who wants a reliable, automatic timepiece with real-world durability. The 200m water resistance and screw-down crown make it more than capable of handling swimming or snorkeling, while the 41mm size makes it a viable daily wearer. It is also a strong pick for those who value a watch with a distinct visual identity that doesn’t simply copy the “Submariner” blueprint.
