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

The lug width of the Omega Aqua Terra 231.13.42.22.02.001 is 20mm. This dimension is binding for compatibility with aftermarket straps: an 18mm strap would be too tight and create lateral play, while a 22mm strap would not fit into the case lugs. Always measure the internal distance between the two lugs to confirm compatibility before purchasing.

For the 231.13.42.22.02.001 we recommend three options based on usage: nile crocodile with vegetable tanning for everyday elegance (the regular grain pairs perfectly with the teak dial design); bordeaux or brown shell cordovan for those desiring noble aging and natural patina over time; navy or grey NATO for those engaging in water activities and requiring moisture resistance. Vulcanized rubber remains ideal in extreme marine environments.

The Omega Aqua Terra 231.13.42.22.02.001 features an integrated bracelet, not removable lugs. To change the strap, you must unscrew the internal spring bar using a specific tool (spring bar remover). Position the watch on a soft cloth, locate the lugs, insert the tool under the spring bar and push gently until the spring bar is released. Subsequently, remove the internal spring bar and replace it with the new 20mm strap. It is advisable to entrust this to a professional to avoid damage to the case.

Durability depends on the type of leather and usage regime. A nile crocodile worked with vegetable tanning can last 5-7 years with moderate daily use; shell cordovan, thanks to its superior cellular density, reaches 8-10 years. Brushed calf (scotch grain) lasts 3-5 years. The critical factor is exposure to moisture: frequent contact with seawater or perspiration reduces useful life. Milano Straps straps include an 18-month warranty and are renewable at no additional cost at the Casati Milano atelier.
