Strap for Seamaster Aqua Terra 150m Co-Axial 41.5 Day-Date Stainless Steel / Black

The lug width of the Omega Aqua Terra 231.10.42.22.01.001 is 20mm. This measurement must be respected exactly when purchasing a replacement strap, as non-compliance risks incompatibility and potential damage to the case lugs.

It depends on use: an alligator or vegetable-tanned calf elevates formal elegance; shell cordovan offers resistance and nobility; NATO or FKM rubber is ideal for marine and sports environments. The Aqua Terra's teak concept dial pairs exceptionally well with regular-grain alligator, which amplifies the dial's reflections.

The Aqua Terra features standard straight lugs. Using a spring bar tool, apply gentle downward pressure on one spring to extract it, then slide the old strap out of the lug. Insert the new strap, then reinsert the spring. Repeat for the other lug. The operation requires care to avoid scratching the case.

Yes, any strap with 20mm lug width is compatible. Milano Straps offers handcrafted 20mm straps in multiple materials (alligator, calf, shell cordovan, rubber, NATO fabric) ready to ship and customizable. For a bespoke experience, the Casati Milano atelier creates made-to-measure straps with an 18-month warranty.

Durability depends on material and use. Vegetable-tanned calf lasts 3–5 years in daily wear; shell cordovan resists 5–8 years. Constant exposure to salt water, chlorine, and perspiration shortens strap life. A quality handcrafted strap, unlike industrial production, develops a noble patina that remains attractive even after years of intensive use.
