Strap for Seamaster Aqua Terra 150M Master Chronometer Small Seconds 41 Stainless Steel / Blue / Rubber

The Omega Aqua Terra 220.12.41.21.03.005 is fitted with a 20 millimeter lug width. This measurement is precise: the strap must respect a 20mm width to fit correctly without looseness or play between the case and the spring bar.

It depends on usage. For formal elegance we recommend cognac or black alligator in vegetable tanning. For sports and water use, thick natural rubber. For daily versatility, Hermès calf leather in warm brown tones. All compatible with 20mm lug width.

Use a spring bar tool to gently push the retaining spring toward the center of the case. Remove the spring bar from the holes and take off the old strap. Insert the new strap by aligning it with the lugs and verify that the spring bar clicks into position with a crisp snap.

Yes, any strap with a 20mm lug width is compatible. On milanostraps.it you will find a collection of artisanal straps available in leather, rubber and fabric, all customizable, including initials and choice of stitching thread.

A fine leather strap (alligator, calf, shell cordovan) lasts 3-5 years with daily wear, depending on frequency of use and climate conditions. Vegetable tanning develops patina and ages better than synthetic tanning. Casati Milano offers an 18-month warranty on all artisanal straps.
