Strap for Seamaster Aqua Terra 150M Co-Axial 41.5 Stainless Steel / Blue / Bracelet

The lug width of the Omega Aqua Terra 231.10.42.21.03.001 is 20mm. This dimension corresponds to the distance between the inner edges of the two lugs (lateral pins) of the case. It is essential to verify this specification when purchasing a replacement strap to ensure a perfect fit.

For this model we primarily recommend straps in alligator (anthracite grey or cognac for maximum elegance), vegetable-tanned calf in dark blue or grey tones for a balance between formality and nautical character, and FKM rubber for more sporty use. The choice depends on the primary use and desired personal aesthetics.

The Aqua Terra 231.10.42.21.03.001 features an integrated lug system, meaning the lugs are not removable. To change the strap, you need to extract the lateral pins from the case using a specialized hammer and punch, then fit the new strap onto the same pins. We recommend consulting a professional for this operation.

Artisanal aftermarket straps offer customization in terms of material (alligator, calf, cordovan), color, thickness and buckle type, at a lower cost than the original Omega strap. The quality of execution and durability depend on the maker: straps crafted with sartorial techniques guarantee longevity equivalent to or superior to originals.

A quality natural leather strap, treated with vegetable or synthetic tanning, has an average lifespan of 3-5 years with daily use, extendable to 7-10 years with regular maintenance (gentle cleaning and conditioning). The natural aging process imparts a patina to the strap that increases the aesthetic value of the overall piece.
