Fit & sizing notes for the Aqua Terra 41

20mm lug width41mm case48mmlug-to-lug
  • Width: buy 20mm straps. Tapered straps listed as 20/18mm or 20/16mm fit too; only the first number has to match. See strap sizes explained.
  • Spring bars: 20mm long, about 2.0mm diameter (spring bar sizes).
  • Ends: the case curves between the lugs, so curved or fitted-end straps close the gap. Straight-end straps still fit.
  • 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 13.2mm thick it's a chunky case: thicker padded leather, rubber/FKM or a heavier NATO balance it visually; very thin straps can look undersized.

Omega Aqua Terra 41 — strap questions

What size strap does the Aqua Terra 41 take?
The Omega Aqua Terra 41 has a 20mm lug width, so you need a 20mm watch strap.
Will any 20mm strap fit the Aqua Terra 41?
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. For a gapless look, pick curved/fitted ends. A metal bracelet needs 20mm end-links made for this model.
What spring bar size does the Aqua Terra 41 use?
20mm long and about 2.0mm in diameter (a typical figure; measure the original bar to be sure).
Is the Aqua Terra 41 good for strap swapping?
Yes. With standard 20mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
