Strap for Seamaster Aqua Terra 150M Co-Axial 30 Red Gold / MOP / Bracelet

The lug width of the 231.50.30.20.55.001 model is 20mm. This measurement represents the distance between the inner edges of the case lugs and remains constant regardless of the strap type mounted. It is essential to measure it correctly to ensure complete compatibility with your replacement strap.

For this model, alligator in dark brown or cognac tones represents the most natural aesthetic choice, enhancing the warm patina of rose gold. Shell cordovan is ideal for those seeking durability and patina development over time. Calf leather offers chromatic versatility and immediate comfort, while NATO or rubber straps are technical choices for frequent water use.

Omega provides a dedicated spring bar tool with this model. Gently remove the elastic lugs from the case using the tool, leveraging from bottom to top to avoid damaging the lugs. Insert the new strap by first aligning one side, then the other, ensuring that the lugs are fully seated in their positions. Verify stability by gently pulling the strap in opposite directions.

All straps with a 20mm lug width are compatible with this model. On milanostraps.it you will find a dedicated collection of 20mm straps in alligator, calf, shell cordovan and rubber, customizable in length, initials and thread color. The Casati Milano atelier also creates custom-made straps with direct selection of leathers.

Durability depends on the material: alligator and calf leather, with moderate daily use, maintain structural integrity for 3-4 years before requiring replacement. Shell cordovan, due to its density, can exceed 5 years while developing a fine patina. Frequency of exposure to water, direct sunlight and humidity accelerates aging. Rubber and NATO straps have similar lifespan but require visual assessment of flexibility.
