Strap for Seamaster Aqua Terra 150M Master Co-Axial 34 Stainless Steel / Grey MOP / Bracelet

The lug width of this model is exactly 20mm. You can verify it by positioning a caliper inside the lugs, from inner wall to inner wall. Any strap with a different width will result in friction and compromised fit.

There is no absolute choice; it depends on usage and aesthetic preference. Alligator delivers maximum sophistication and echoes the nautical heritage; vegetable-tanned calf offers versatility and a patina that ages beautifully; shell cordovan ensures durability and that natural lustre which mirrors the interplay of light on the brushed case.

The Omega Aqua Terra features a screw-down lug system (pin type). Use an appropriate lug removal tool to extract the pins securing the strap to the case. Insert the pins into the new strap and screw gently, without forcing. If you prefer to avoid any risk, you can entrust the work to a professional.

Technically yes, but not recommended. Generic straps do not account for the specific proportions of the model, construction quality, and aesthetic coherence with the 34mm case and its design. A bespoke artisanal strap guarantees perfect mechanical compatibility and visual harmony.

A quality leather strap (alligator, calf, shell cordovan) worn regularly typically lasts 3–5 years before requiring replacement. Lifespan depends on frequency of wear, environment (humidity, perspiration), and tanning quality. Bespoke straps from Casati Milano include an 18-month warranty and can be regenerated with restoration services.
