Fit & sizing notes for the Ocean One 42
- 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 2.5mm diameter. These are fat bars, so pick straps with holes made for them, or swap to thinner 22mm bars for slim leather (spring bar sizes).
- Wrist fit: at 50mm lug-to-lug it should sit within the top of wrists from about 16.7cm up (rule of thumb: lug-to-lug under ~30% of wrist size). That's longer than 88% of the watches in our index. See what size watch suits your wrist.
- Strap thickness: at 13mm thick it's a chunky case: thicker padded leather, rubber/FKM or a heavier NATO balance it visually; very thin straps can look undersized.

Steinhart Ocean One 42 — strap questions
What size strap does the Ocean One 42 take?
The Steinhart Ocean One 42 has a 22mm lug width, so you need a 22mm watch strap.
Will any 22mm strap fit the Ocean One 42?
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 Ocean One 42 use?
22mm long and about 2.5mm in diameter (a typical figure; measure the original bar to be sure). These are thicker 'fat' bars, so heavier straps suit it best.
Is the Ocean One 42 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.
