Strap for Seamaster Aqua Terra 150M Co-Axial 38.5 Stainless Steel / White / Bracelet

The Omega Aqua Terra 231.10.39.21.54.001 has a lug width of 20mm, which is the distance between the strap attachment pins measured from the center of one to the other. This width allows compatibility with a wide range of aftermarket straps in leather, rubber, and technical materials.

It depends on the intended use: dark brown or black alligator enhances sporty elegance while maintaining daily versatility; shell cordovan represents the most refined choice thanks to the natural patina it develops over time; vegetable-tanned calf offers resistance and consistent softness; FKM rubber is ideal for actual marine environments. All these materials are available in 20mm format.

Using a spring bar remover tool, insert the thin end under the elastic pin that connects the strap to the case lugs. With gentle outward pressure, the pin retracts and the strap detaches. To install the new strap, align the holes with the pins and press until the locking mechanism engages. It is advisable to use a soft surface (cushion) to avoid scratches on the case during the operation.

Yes, provided the strap is specifically sized for 20mm lug width. All straps made for this width — regardless of brand — are mechanically compatible. The choice is therefore based on material, color, and construction quality according to personal preferences.

The lifespan of a leather strap varies between 2 and 5 years depending on frequency of use, climatic conditions, and type of leather. Alligator or shell cordovan, thanks to superior fiber density, tend to last longer than standard calf. Daily exposure to moisture, sweat, and UV rays accelerates aging. Periodic maintenance — cleaning with a damp cloth and annual conditioning — significantly extends the strap's useful life.
