Invicta Watch Band Size by Model
Invicta sells dozens of collections at wildly different case sizes, and the band width follows the case rather than the name on the dial: the 40mm Pro Diver takes 20mm at the lugs, the 44mm Pro Divers and the Grand Diver take 22mm, and everything oversized (Venom, Bolt Zeus, Subaqua) lands at 26mm or wider. This page lists the band width, the gap between the lugs, for the Invicta families people actually replace straps on. Every row is confirmed by two independent sources, and where a family varies by case size the case-to-lug rule is stated instead of a fake single number.
Invicta strap width by model line
| Model | Case | Band width | Notes |
|---|---|---|---|
| Pro Diver coin-edge 8926OB / 8926 | 40mm | 20mm | The base automatic diver; bracelet tapers 20 to 18mm |
| Pro Diver 8929 and two-tone variants | 40mm | 20mm | Same 40mm case in dressier finishes |
| Pro Diver quartz and scalloped-bezel 40mm family | 40mm | 20mm | Every 40mm Pro Diver reference found shares 20mm |
| Pro Diver 44mm (2307, 10492, GMT 5124, meteorite 32822) | 44mm | 22mm | The case step from 40 to 44mm adds 2mm of strap |
| Grand Diver (49479, 38568, 26977 and siblings) | 47mm | 22mm | OEM replacement bands listed at 22mm across references |
| Subaqua Noma III (0929, 5510 at 28mm; 18526, 21726 at 29mm) | 50mm | 28-29mm | Width varies by reference; check the caseback number |
| Subaqua Noma V | 53mm | 26mm | Aftermarket silicone tapers 26 to 24mm |
| Subaqua Noma IV | 53mm | 32mm | The widest lugs Invicta ships; 32mm straps, 26mm buckles |
| Venom (25968, 0361, 5735, 6110) | 52-53mm | 26mm | Official Band Size 26mm; genuine and aftermarket straps agree |
| Bolt Zeus / Bolt Zeus Magnum (14071, 43115) | 52-53mm | 26mm | Cable-bezel chronographs on straps and bracelets |
| Reserve 33809 and the 26mm Reserve family | 56mm | 26mm | The Russian Diver 1090 also takes 26mm |
| Angel women's line (0243, 0244, 48846, 16122, 1644) | 32-38mm | 18mm | Nearly every Angel OEM band is listed at 18mm |
Because the family varies by case, the honest way to read Invicta is as a case-to-lug mapping: 40mm cases take 20mm, 44 to 47mm cases take 22mm, and 50mm and up starts at 26mm and climbs to 28, 29 or 32mm on the Subaqua Noma line. The Pro Diver meteorite 32822 also exists in a 38mm small size whose width is not consistently documented; measure that one before ordering. Reference numbers are on the caseback, and Invicta's own product pages list a Band Size for current models.
The pin size question, answered straight
People searching "Invicta pin size" are usually trying to size a bracelet or replace a lost link pin, not buy a strap. The common answer is 1.5mm friction pins: the link-pin kits sold explicitly for Invicta bracelets are 1.5mm diameter, and eBay's Invicta band-pin listings lead with thick 1.5mm pins for steel bands. That is a majority answer, not a universal one. Esslinger's pin reference lists link pins from 0.70mm up to 1.80mm used with friction sleeves, and Invicta builds across many factories and years, so match the pin you push out rather than assuming. Invicta's own service price list treats "spring bars or screws for band" as an orderable part, which is the clean fix for a lost one.
The other half of the question is how the strap attaches, because Invicta uses all three styles. Total Watch Repair's measuring guide lays them out: straight-end straps can be replaced by any strap of the same lug width; curved-end straps accept either the original or a straight-end strap of the same width; integrated bands must be replaced with the original strap, matched by the case number on the caseback. If your Invicta has a built-in bracelet look with no visible spring bar gap, it is integrated and the table above does not apply to it. The technique for measuring the gap yourself is on the measuring guide, the bars themselves are covered in spring bar sizes, and the tool for the swap in the spring bar tool guide.
Interchange families, so you can reuse straps
- The 20mm family: every 40mm Pro Diver. This is the most stocked strap width in the world, shared with the Seiko Alpinist, the Casio Duro, and most Galaxy Watches. One 20mm rotation serves the whole 40mm Pro Diver line.
- The 22mm family: 44mm Pro Divers and the Grand Diver, sharing the SKX007 and Turtle width covered on the Seiko band size chart.
- The 26mm family: Venom, Bolt Zeus, the 26mm Reserves, Russian Diver, and the Subaqua Noma V. Aftermarket selection is real but thinner than 22mm; check stock before committing to a specific strap.
- The odd ones: the Noma III's 28 and 29mm and the Noma IV's 32mm are widths almost nobody but Invicta uses; straps exist but mostly from Invicta's own band service and a handful of specialists. The Angel line's 18mm is the one women's width that is genuinely easy to shop for.
Finding your own number if the table misses it
Invicta model numbers live on the caseback, and both invictawatch.com product pages and the OEM band shops (invictawatchbands.com in the US, invictaservice.com in Europe) index by that number. 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 every brand. For whether a 52mm Venom belongs on your wrist at all, that is the case size by wrist question, entirely separate from band width.

Once you know the width: the general band size chart sets Invicta's widths in context, strap length by wrist makes sure the new strap is also long enough, and how to adjust a watch band walks the pin-and-collar and screw-link jobs step by step. The sibling brand pages are the Seiko band size chart, the Casio strap size chart, the Timex band size chart, and the Citizen band size chart; the Bulova band size chart covers the other brand people pair with Invicta at the same counter. The watch strap taper chart decodes the second number in a 26/24 listing.
