Fit & sizing notes for the Duro (Marlin)

22mm lug width44mm case48mmlug-to-lug
  • Width: buy 22mm straps. Tapered straps listed as 22/20mm or 22/18mm fit too; only the first number has to match. See strap sizes explained.
  • Spring bars: 22mm long, about 2.0mm diameter (spring bar sizes).
  • Wrist fit: at 48mm lug-to-lug it should sit within the top of wrists from about 16.0cm up (rule of thumb: lug-to-lug under ~30% of wrist size). That's longer than 62% of the watches in our index. See what size watch suits your wrist.
  • Strap thickness: at 12mm thick it's mid-thickness, so most straps suit it; padded leather and NATOs both balance well.

Casio Duro (Marlin) — strap questions

What size strap does the Duro (Marlin) take?
The Casio Duro (Marlin) has a 22mm lug width, so you need a 22mm watch strap.
Will any 22mm strap fit the Duro (Marlin)?
Most will. Width is the main thing to match, but also check that the strap's spring-bar holes suit the bars, and that the strap is thin enough to clear the case between the lugs. A metal bracelet needs 22mm end-links made for this model.
What spring bar size does the Duro (Marlin) use?
22mm long and about 2.0mm in diameter (a typical figure; measure the original bar to be sure).
Is the Duro (Marlin) good for strap swapping?
Yes. With standard 22mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
