Strap for Seamaster Aqua Terra 150M Shades Master Chronometer 38 Stainless Steel / Shell Pink / Bracelet

The lug width is 19mm. This is the standard Omega measurement for 38mm Aqua Terra models. Verify by measuring the distance between the internal shoulders of the lugs: it must be exactly 19mm, tolerance ±0.2mm for a precise fit without play.

It depends on use: vegetable-tanned alligator niloticum is the highest for elegance and patina development over time; shell cordovan for durability and tactile memory; striped calf for pronounced texture and immediate comfort. For frequent marine environments, FKM Viton rubber with no water absorption.

Obtain a flat-tip spring bar removal tool. Position the watch on a soft surface. Insert the tip under the retention spring of one lug, gently press to compress the internal shoulder, pull the pin outward. Repeat on the other side. Insert the new strap by aligning the pins with the holes, press until it clicks into place.

Yes, all straps with nominal width 19mm are compatible with the 220.10.38.20.10.005. Verify that tolerance is ±0.2mm to avoid play. On milanostraps.it you will find artisanal tested straps and customizable on demand.

With quality leather (alligator, calf, shell cordovan) and regular maintenance (monthly cleaning, regular air exposure), the strap lasts 3–5 years for daily use. Shell cordovan can reach 7–10 years thanks to material density. FKM rubber lasts 5–8 years without loss of tactile properties.
