Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Sedna Gold / Silver / Rubber

The lug width of the Omega Aqua Terra 220.22.38.20.02.001 is 19mm. This means the strap must have a spacing of 19mm between the spring bars to be compatible with the 38mm case. It is essential to verify this measurement before purchasing an aftermarket strap to avoid incompatibility.

Alligator represents the most elegant choice to enhance the two-tone Sedna Gold and steel: the natural grain and patina over time create harmony with the understated luxury of this model. However, dark brown calf leather offers superior quality-to-practicality ratio for everyday wear, while vegetable tanning appeals to those desiring visible and deliberate strap aging.

Strap replacement requires a dedicated tool — spring bar remover — to extract the spring bars from the case. Position the watch on a soft pad (to avoid scratching), insert the remover into the lateral slot of the spring bar and push gently upward. The spring bar will retract and the strap will detach. For the new strap, align the spring bars with the slots on the case and press until they click into position.

A quality leather strap — alligator, calf, or vegetable-tanned — has a lifespan of 3-5 years with regular daily wear, depending on sun exposure, humidity, and cleaning frequency. Vegetable-tanned leather tends to last slightly longer than standard calf. Regular treatments with protective cream significantly extend the strap's life.
