Strap for Seamaster Aqua Terra 150M Master Chronometer 41 Stainless Steel / Grey / Rubber

The Omega Aqua Terra 220.12.41.21.06.001 is equipped with a 20mm lug width. This measurement represents the distance between the horizontal case attachments where the strap is inserted. To verify it, measure with a caliper the width of the space between the pins that support the strap.

For the 220.12.41.21.06.001 we recommend a vegetable-tanned alligator in black or brown for classic elegance, or a shell cordovan for those who prefer leather that develops patina over time. For sports contexts, a cotton-linen NATO or FKM rubber offer superior practicality while maintaining aesthetic coherence with the model's nautical DNA.

The procedure is simple: use a spring bar tool (a tool with a bifid end) to compress the elastic pin that supports the strap. By pushing inward, the pins retract allowing you to remove the strap from the case. To install the new strap, align the holes with the pins and push until the locking click.

All straps with a 20mm lug width are compatible. You can choose between alligator, calf, shell cordovan, NATO, rubber and fabrics, purchasing online or requesting a custom creation at the Casati Milano atelier for bespoke tailoring.

The durability varies based on material and use: a vegetable-tanned alligator lasts 3-5 years with regular wear, while shell cordovan can last 5-7 years developing prized patina. FKM rubber has similar durability (3-5 years) but degrades more uniformly. Periodic maintenance (cleaning, conditioning) significantly extends the strap's lifespan.
