Strap for Seamaster Aqua Terra 150M Co-Axial 38.5 Stainless Steel / Yellow Gold / Grey / Bracelet

The Omega Aqua Terra 231.20.39.21.06.002 has a lug width of 20mm. This is the exact distance between the case lugs where the strap is attached. Always verify this dimension before purchase to ensure perfect compatibility.

For the 231.20.39.21.06.002, we recommend vegetable-tanned alligator (classic elegance), shell cordovan (deep patina for evening occasions), or embossed calf (aesthetic versatility). The choice depends on use: formal, sport-nautical, or daily wear. All straps must have a 20mm lug width.

Strap changing requires a springbar tool, a specific tool for removing the elastic pins (springbars) that attach the strap to the case lugs. Insert the tool into the lateral notches of the attachment, push toward the center to compress the spring, and slide the strap out of the lugs. Repeat the procedure on the opposite side. For a flawless result, entrust the operation to an expert if it's your first time.

All straps with a 20mm lug width are compatible with the 231.20.39.21.06.002. Milano Straps offers a wide selection of aftermarket straps in alligator, calf, shell cordovan and other materials, customizable in length, color and finish. The Casati Milano atelier also creates bespoke straps tailored to your specifications with personally selected leathers.

The lifespan of a leather strap depends on the material and usage. Vegetable-tanned alligator typically lasts 3-5 years with moderate daily use. Shell cordovan, being more robust, can exceed 5-7 years. Embossed calf has a lifespan of 2-4 years. These timeframes extend significantly with regular care (cleaning, protection from excessive moisture) and occasional use. Milano Straps' 18-month warranty covers manufacturing defects.
