Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Stainless Steel / Sedna Gold / Diamond / Grey - Diamond / Alligator

The Omega Aqua Terra 220.28.34.20.59.001 has a lug width of 16mm. This dimension is measured in millimetres between the case lugs and is essential to ensure compatibility with aftermarket straps. Precise measurement with a digital caliper is necessary to avoid fitting errors.

Vegetable-tanned alligator represents the primary aesthetic choice: the natural texture of the scales dialogues perfectly with the elegance of the case. Shell cordovan offers an alternative for those seeking material compactness and longevity. In summer, fine-grained calf leather in light tones amplifies the luminosity of the Sedna Gold.

Strap replacement requires a spring bar remover tool: position the tool in the lateral groove of the retaining spring, apply pressure inward and gently lift to release the pin. Repeat on the other side. Insert the new strap by aligning the lug with the pins and lower until the spring locks. The operation requires care to avoid scratching the case.

Yes, the 220.28.34.20.59.001 accepts any certified 16mm lug width strap. Compatibility is guaranteed by the standardisation of the measurement, regardless of the strap manufacturer. It is essential to verify that the strap has been measured accurately by the seller.

Durability depends on the material and usage regime. Vegetable-tanned alligator and shell cordovan maintain functionality for 4-6 years with daily use and proper maintenance. Calf leather has shorter life cycles (2-4 years) due to lower material density. Moisture and prolonged direct sunlight exposure significantly reduce durability. Periodic conditioning with colourless wax extends longevity.
