Strap for Seamaster Aqua Terra 150M Co-Axial 42.2 Stainless Steel / White

The Omega Aqua Terra 2802.34.37 has a lug width of 20mm. This value represents the distance between the attachment pins (lugs) of the case. You can verify it by measuring directly with a caliper or ruler the perpendicular distance between the two fastening points of your current strap. 20mm straps are specifically compatible with this model.

It depends on your intended use. For formal and professional contexts, we recommend alligator or vegetable-tanned calf leather, which combine elegance and natural patina. If you intend to take advantage of water resistance up to 150 meters, shell cordovan is surprisingly robust and durable. For a sporty approach, natural rubber with integrated deployant or NATO fabrics offer maximum practicality. Milano Straps has complete sample sets available to evaluate the final result on your case.

Changing the strap requires a specific tool, the spring bar tool, which allows you to compress and remove the pin from its seat without damaging the case. Position the watch on a soft surface, insert the tool into the pin slot, compress gently and retract the strap. Repeat on the other side. To install the new strap, insert the pin into the replacement lug and push it into position until you hear the safety click. If you prefer a risk-free procedure, Milano Straps and the Casati Milano atelier offer professional strap-changing service.

All 20mm straps are mechanically compatible with the 2802.34.37. Milano Straps offers a selection of 20mm straps in alligator, calf, shell cordovan, rubber and fabric, with customization options in sizes, initials and choice of stitching thread. The Casati Milano atelier also creates bespoke straps to order, with personal choice of leathers and updates via WhatsApp.

Durability depends on the material and use. A vegetable-tanned calf strap, worn daily under normal conditions, typically lasts 3-5 years before requiring replacement. Alligator, being denser, can last 5-7 years. Shell cordovan, thanks to its natural density, can exceed 7-10 years. Natural or synthetic rubber maintains structural integrity longer, but requires regular cleaning. Buckle or keeper wear may accelerate the need for replacement. Milano Straps provides an 18-month warranty on bespoke straps made by the Casati Milano atelier.
