Strap for Seamaster Aqua Terra 150M Co-Axial 36.2 Stainless Steel / Black

The Omega Aqua Terra 2804.50.37 has a lug width of 20mm, the standard distance between the two lugs. Measuring is simple: use a digital caliper and position it between the two internal pins of the case. All 20mm straps in our catalogue are mechanically compatible with this model.

It depends on use. For formal occasions, we recommend vegetable-tanned alligator or shell cordovan: they develop patina over time. For immediate comfort, Italian calf. For summer and water activities, black or blue FKM rubber. The Aqua Terra accommodates any material; the choice reflects your personal style.

Position the watch on a soft pad. Using a spring bar tool (special lever for spring bars), gently push inward on one side of the bar to loosen it. Remove the bar, take off the old strap, insert the new one by aligning it with the holes, and reinsert the bar. Verify that it is locked on both sides before wearing the watch.

Yes, if the size is certified at 20mm. Mechanical compatibility is guaranteed: standard spring bars fit and lock correctly. However, only straps intentionally made for Omega 36mm respect the proportions and finish of the case. Our straps are physically tested on this model.

It depends on the material and use. Daily calf: 3-4 years. Alligator or cordovan: 5-7 years, even with intensive use. FKM rubber: 4-5 years if not constantly exposed to direct UV rays. Proper maintenance—monthly cleaning with a damp cloth, annual buckle service—significantly extends the life. The Milano Straps warranty covers 18 months.
