Strap for Seamaster Aqua Terra 150M Master Chronometer 41 Stainless Steel / Black / Bracelet

The Omega Aqua Terra 220.10.41.21.01.002 is fitted with a 20 mm lug width, a standard specification that ensures compatibility with the wide range of artisanal straps available on the market. To verify the measurement correctly, insert a ruler between the case and strap at the level of the lower attachment: the distance between the inner edges of the lugs must be exactly 20 mm.

The choice depends on intended use and desired character. Vegetable-tanned alligator creates understated elegance with patina development over time; nubuck calf offers maximum comfort; Shell Cordovan guarantees unparalleled brilliance and density; ballistic canvas NATO emphasizes the original sporting vocation; FKM rubber is ideal for marine environments. Each material completely transforms the instrument's character.

The Aqua Terra 220.10.41.21.01.002 uses standard spring bars. Obtain a dedicated tool (spring bar removal tool), insert it into the lateral gap between case and strap, apply gentle downward pressure to release the spring, and the strap slides away. The operation requires care to avoid scratching the case. If you prefer to entrust the operation to professionals, Casati Milano performs it by appointment.

Yes, provided the lug width is genuinely 20 mm and the strap is manufactured to correct standards. The straps available on MilanoStraps.it are all verified for this compatibility. Caution: some third-party manufacturers claim 20 mm but present tolerances of ±0.5 mm that cause angular play. Rely on certified suppliers.

Durability depends on material and frequency of use. Vegetable-tanned alligator maintains structural integrity for 4-6 years of daily wear, developing patina. Nubuck calf has slightly shorter durability (3-5 years) as the finish is more delicate. Shell Cordovan, being extremely dense, can exceed 10 years. Casati Milano offers an 18-month warranty on all manufactured straps, with the option of leather regeneration at reasonable cost.
