An honest look at the Bulova Marine Star 98B203 – specs, real owner reviews, and where it falls short on water resistance. Plus the best price in Ireland.
Bulova Marine Star Chronograph Review: The 98B203
The Marine Star has been Bulova's affordable chronograph line since 2014, and the 98B203 is one of the longer-running references in it, a stainless steel quartz chronograph with a black dial and 100m water resistance.
The wider Marine Star range spans water resistance from 100m up to 200m depending on the specific model, so it matters which reference you’re actually looking at. This review is built from Bulova’s own specifications, Amazon.ie’s listing data, and published reviews and owner reports from watch forums and watch-focused publications, rather than a hands-on test unit at menswatches.ie. For the rest of the range, see our guide to Bulova watches for men.

43mm stainless steel quartz chronograph
- Price €244.11 on Amazon.ie at time of writing, mid-pack for a new Marine Star quartz chronograph, which typically runs €200 to €400.
- Case 43mm stainless steel case, 10.5mm thick, 22mm strap width.
- Water resistance 100m: fine for showers and swimming, but below the roughly 200m threshold most reviewers use as the real cutoff for diving, and it isn’t ISO 6425 dive-certified.
- Movement Quartz. Owner reports on watch forums describe it as well-regulated and accurate.
A detailed mini-review of this exact reference on WatchUSeek forums found the quartz movement well set up, with the second hand landing precisely on each marker, and described the matte black dial as catching light in an interesting way. That owner swapped the stock steel bracelet for a leather and grey strap for comfort, and singled out the subtle branding: the Bulova tuning fork logo appears only on the crown. Their main criticism: for a design that leans on diver-watch styling, a 100m rating and the absence of a locking crown felt like a missed opportunity. Separately, a dedicated watch review site covering this reference echoed the sizing and build notes and rated it fair value for a quartz chronograph in this price range. Multiple reviewers of the wider Marine Star chronograph family make the same point independently: a 100m rating is enough for the shower or the pool, but it falls short of what’s generally expected before you’d trust a watch on an actual dive.
The matte black dial catches light differently depending on the angle, something owners specifically call out in hands-on reviews of this reference.
A well-specced, accurately-regulated quartz chronograph at a price most automatic watches don’t reach. It borrows diver-watch styling without diver-watch certification, so treat the 100m rating as shower-and-swim, not dive-ready. Within that limit, it’s a solid everyday chronograph with a bracelet many owners end up swapping for a strap.
Specifications
- Chronograph subdials and a 43mm case give real wrist presence without oversized proportions
- Owner reports describe the quartz movement as well-regulated and accurate
- Priced mid-pack for a new Marine Star chronograph, well under comparable Swiss automatics
- Stainless steel bracelet included, with a common 22mm lug width if you want to swap it
- 100m water resistance sits below the roughly 200m threshold generally expected of a true dive watch
- No ISO 6425 dive certification despite the Marine Star name and diver-influenced styling
- Quartz movement, not automatic: no appeal for buyers who specifically want mechanical
- Stock on Amazon.ie has been limited at times, so it’s worth checking availability before counting on it
98B203 or a different Marine Star reference?
The Bulova Marine Star 98B301 below is rated to 200m with a screw-down crown, the dive-rated option in the same range. The 98B203 tops out at 100m.
The 98B203 is quartz. Bulova also sells automatic Marine Star chronographs at a higher price if a mechanical movement matters to you.
This is where the 98B203 fits best: quartz accuracy, chronograph styling, and a mid-range price for the collection.
Frequently Asked Questions
Is the Bulova Marine Star 98B203 waterproof for swimming?
Yes, for showering and casual swimming. It carries a 100m rating, but reviewers of this model and the wider Marine Star chronograph family consistently note that falls short of the roughly 200m threshold and ISO 6425 certification expected of an actual dive watch.
Is the 98B203 an automatic or quartz watch?
Quartz. Owner reports describe the movement as well-regulated and accurate. Bulova also sells automatic Marine Star chronographs at a higher price if you want a mechanical movement instead.
What wrist size does a 43mm case suit?
43mm sits at the larger end of mid-size. It generally suits average to larger wrists comfortably; smaller wrists may find it sits a little proud.
Does the strap fit other 22mm bands?
Yes. The lug width is 22mm, a common size, so third-party bracelets and straps are widely available if you want to swap the stock bracelet.
Is the movement accurate?
A detailed owner mini-review on WatchUSeek forums specifically covering this reference found the second hand landing precisely on each marker, describing the movement as well set up.
Is the stock steel bracelet comfortable?
Reports vary by wrist. At least one owner reviewing this exact reference swapped the metal bracelet for a leather strap for comfort. The 22mm lug width makes that an easy change if the stock bracelet doesn’t suit you.
Conclusion
- 43mm stainless steel chronograph, quartz movement, owner-confirmed accuracy
- 100m water resistance: showers and swimming, not diving. Look at the 200m 98B301 below for that.
The Marine Star 98B203 borrows diver-watch styling without diver-watch certification. What it actually delivers is an accurately-regulated quartz chronograph with a stainless steel bracelet, genuine 100m splash and swim resistance, and a mid-pack price for the Marine Star range. For Irish buyers who want that look for daily wear rather than diving, owner and reviewer reports back it up as a fair pick. Anyone planning to dive with the watch should look at Bulova’s 200m-rated Marine Star references instead.
