Strap for Seamaster Aqua Terra 150M Co-Axial 43 GMT Chronograph Stainless Steel / Grey / Bracelet

The Omega Aqua Terra 231.10.43.52.06.001 has a lug width of 20mm. This measurement, taken between the inner edges of the two case lugs, ensures compatibility with artisanal and aftermarket straps of identical dimension. To verify it, position a ruler between the lugs: the distance must be exactly 20mm.

For the 231.10.43.52.06.001, an alligator strap in tobacco or cognac colour offers maximum aesthetic contrast with the anthracite dial. Alternatively, vegetable-tanned calf leather in brown-hazelnut develops natural patina over time. For intensive sports use, bordeaux shell cordovan or black FKM rubber guarantee durability and resistance.

Remove the original strap using a dedicated tool (spring bar tool) to extract the metal lugs from the holes on the case lugs. Insert the new artisanal strap (20mm) ensuring that the lugs are perfectly aligned. Avoid forcing: a correct 20mm lug width enters with moderate pressure.

Yes, provided that the artisanal or aftermarket strap has exactly 20mm lug width. Brands such as Milano Straps offer leather and rubber straps specifically cut for this dimension, with customizable finishes (initials, edging, colours) and structural warranty.

A fine leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 3–5 years with daily use. Durability depends on exposure to moisture, heat and repetitive movements of the keepers. Artisanal straps from ateliers such as Casati Milano come with an 18-month guarantee and allow for quick replacement thanks to 20mm compatibility.
