Bulova Watch Band Size by Model

Bulova publishes a lug width on nearly every current product page, which should settle everything, except the retailer compatibility tables circling the brand contradict it in two places: the Marine Star is widely tabulated at 24mm while Bulova's own 43 to 45mm models say 22mm, and the Curv is tabulated at 20mm while Bulova's own curved chronograph says 25mm. This page lists the band width, the gap between the lugs, for the Bulova families people actually replace straps on. Every row is confirmed by two independent sources, and the two places where the sources genuinely disagree are flagged rather than averaged.

Bulova strap width by model family

Two reference families are worth a warning before the detail sections. The current Marine Star Series C watches (the 43mm 96B426, the 43mm 96B382, the 45mm 98B301, the 45mm 97A174) all list Lug Width 22mm on Bulova's own pages, while one widely-copied retailer compatibility table lists the "standard Marine Star" at 24mm and the "Marine Star Chronograph" at 19mm. Those two figures describe older references, not the current line; trust the model page for your exact number. And the 44mm Precisionist Icon chronographs are 24mm while the 42mm Langford three-handers are 22mm, so "Precisionist" alone does not answer the question; case size and hand count do.

The Curv exception, and why one strap table says 20mm

The Curv is the one Bulova that does not play by the straight-lug rule. Bulova's official product pages list Lug Width 25mm for the 98A162 chronograph and the Marc Anthony 97A185, and Trifecta Watches and Hard Rock Shop's dealer listings agree on 25mm for the 98A162. The retailer compatibility table that lists the Curv at 20mm appears to describe the strap-end width rather than the lug width on these curved titanium cases, so treat 25mm as the number that matches the factory strap and the dealer spec. The practical caveat: a curved case with open lugs accepts some standard straps (owners report thinner 20mm two-piece straps passing through on the Reddit CURV workaround thread), but a stiff flat strap will fight the case curvature. Soft rubber and thin leathers follow the curve; thick padded straps will not. This is a fit question rather than a width question, so the measuring technique is on the measuring guide and the curved-end strap discussion on the band size chart.

The screw question: pin-and-tube is the Bulova default, and no documented screw thread exists

People searching "Bulova band screw size" are usually staring at a bracelet link. The honest answer is that Bulova does not publish a screw thread specification for its bracelets, and nobody credible has tabulated one, so this page will not invent a figure. What is documented: the standard Bulova bracelet is a pin-and-tube construction, where a thin friction pin passes through a sleeve inside the link, and the sizing method is a push-pin punch or sizing-tool press. Esslinger's pin reference gives the generic sizing logic (pins run 0.70 to 1.80mm with matching sleeves, and the pin you push out is the pin you reorder), and the wristwatch-repair trade documents pin-and-tube as the Bulova norm. Some heavier Bulova bracelets use screw links instead; there the fix is a small jeweler's Phillips or flathead that matches the screw head you can see on the link's face, not a published Bulova thread size. If a link fastener is lost, Bulova's own parts channel (and the mastersintime OEM strap shop) supplies bracelet parts by case number, which is the reliable path. The step-by-step removal walkthrough is on the how to adjust a watch band page, which owns this territory; this page only settles which fastener family you are looking at.

Interchange families, so you can reuse straps

• The 20mm family: Lunar Pilot in both case sizes, A-15 Pilot, Frank Lloyd Wright editions, and the Curv's strap-end dimension if you go the standard-strap route. Shared with the SKX007 width on the Seiko band size chart and the whole men's Timex line on the Timex band size chart.
• The 22mm family: current Marine Star, Precisionist Langford, Wilton, BVA, Military UHF. The most useful width to own if you buy Bulova; it is also the Citizen Promaster width on the Citizen band size chart.
• The 24mm family: Precisionist and Icon chronographs. Big-case territory, also the Invicta Venom and Bolt width on the Invicta band size chart.
• The odd ones: the Hack Watch's 18mm, the Curv's 25mm, and the Devil Diver's contested 19 or 20mm. All three reward measuring before ordering.

Finding your own number if the table misses it

Bulova model numbers (96B251-style) are on the caseback, and bulova.com product pages carry a Lug Width field for current models. If your reference is not in the table, measure the gap between the lugs where the strap sits: the measuring guide covers the technique, and the lug width chart explains what the number means across brands. For whether a 45mm Lunar Pilot suits your wrist at all, that is the case size by wrist question, separate from band width.

Once you know the width: the general band size chart sets Bulova's widths in context, strap length by wrist makes sure the new strap is long enough, and how to adjust a watch band owns the link-removal walkthrough this page defers to. The sibling brand pages are the Citizen band size chart (Bulova's parent company, and the shared 22mm Promaster width), the Seiko band size chart, and the Invicta band size chart for the mall-counter stablemate. The lug width chart by brand holds the full ladder.
