Strap for Seamaster Aqua Terra 150M Co-Axial 36.2 Red Gold / Yellow Gold / Diamond / MOP / Bracelet

The reference 2009.75.00 features a 20mm lug width. This dimension is critical when purchasing compatible straps: even one millimeter of difference would compromise the fit to the case lugs and pose a risk of the watch falling off. Always verify this measurement before ordering an aftermarket strap.

Black or dark brown alligator represents the pinnacle of elegance, enhancing the two-tone details of the case. Vegetable-tanned calf leather is equally refined and develops a natural patina over time. For daily wear in humid environments, black rubber offers practicality without aesthetic compromise. Avoid cool colors such as blue and green, which create visual conflict with the iridescent mother-of-pearl dial.

Use a specialized tool (spring bar tool) to gently compress the springs that secure the strap to the case lugs. Position the tool in the small grooves on the sides of each lug, push inward to release the spring, and remove the original strap. Insert the new strap onto the pins, ensuring the spring is fully seated in its slot. Verify that the strap is perpendicular to the case before wearing the watch.

It depends on the manufacturer. Artisanal straps crafted from premium leather (alligator, shell cordovan, vegetable-tanned calf) can equal or exceed the quality of original Omega straps in terms of raw material and hand craftsmanship. However, original Omega straps benefit from pre-fitting to the case and warranty certification. An optimal solution is to commission a custom strap from a specialized atelier, which guarantees personalization and durability.

A quality calf leather strap, worn daily, has an average lifespan of 3-5 years before showing visible wear at stress and flex points. Alligator, being more resistant, can last 5-8 years. Longevity depends on exposure to moisture, perspiration, drying cycles, and proper maintenance. Avoid prolonged water immersion and dry the strap with a soft cloth after water exposure. A well-maintained strap can be restored through reconditioning by a specialized artisan.
