Some watches feel like they belong in a glass case. The Bulova Marine Star Heritage 98B451 feels like it belongs on a wrist that actually goes places—dockside at sunrise, city streets at midnight, and anywhere in between where a tool-watch silhouette just works.

This is a 150th Anniversary Special Edition that leans into Bulova’s bold 1970s Marine Star design language—big numerals, strong hands, and a purposeful timing bezel that looks born for salt air. But it’s not nostalgia for nostalgia’s sake. Bulova pairs that vintage attitude with a modern powerhouse: the Precisionist movement vibrating at 262 kHz, built for extremely stable timekeeping and instrument-like chronograph performance.

In other words: it’s heritage with horsepower.

The dial: tool-watch clarity you can read instantly

This model is built for legibility—big numerals, bold hands, and luminous fill that stays visible when conditions get dim. It has that “instrument panel” vibe: you don’t admire it first… you use it first.

The bezel: the detail that makes the watch feel fast

A dive-style timing bezel instantly changes a chronograph’s personality. It adds urgency and utility—and on the 98B451, the contrasting bezel tones give the watch a sporty punch without turning it into a loud fashion piece.

The caseback: collector-friendly, not gimmicky

The commemorative anchor caseback is a subtle nod to the Marine Star theme. It’s the kind of detail you appreciate every time you take the watch off—quiet ceremony, done right.

Precisionist 262 kHz: Why This Watch Isn’t “Just Another Quartz Chronograph”

Here’s what makes the 98B451 different: Bulova’s Precisionist system operates at 262 kHz, far higher than standard quartz. In real-world terms, that means:

Very stable, high-precision timekeeping (set it and forget it)

A chronograph experience that feels more “instrument-grade” than typical quartz

Timing capability down to 1/20 of a second, paired with practical everyday convenience

If you love accuracy and performance but don’t want the upkeep of a mechanical chronograph, this is the sweet spot.

200m Water Resistance + Screw-Down Crown: Real “Marine Star” Cred

The headline spec is 200m water resistance—paired with a screw-down crown for extra security. That combination gives you serious confidence for:

swimming

boating

beach days

rough weather

Everyday wear without babying the watch

This is the kind of rating that turns a good-looking sports chronograph into a watch you can actually live in.

Bracelet & Wearability: Solid, Secure, and Built to Match the Case

On wrist, the 98B451 feels substantial. The stainless steel bracelet and the push-button safety clasp reinforce that “tool” character—secure, durable, and designed to take a beating.

The 22mm lug width is also a big plus if you want to customize:

rubber for summer

sailcloth for a true maritime vibe

leather for a vintage tool-watch look
