Strap for Seamaster Aqua Terra 150M Master Chronometer Small Seconds 41 Sedna Gold / Silver / Bracelet

The Omega Aqua Terra 220.50.41.21.02.002 features a lug width of 20mm. This width is specific to the 41mm cases in the Aqua Terra collection and ensures balanced proportions on standard wrists. To verify the measurement, use a digital caliper perpendicular to the case plane, measuring the space between the lug pins (spring bar).

For the instrumental vocation of the 220.50.41.21.02.002, we recommend alligator in dark tones (brun noir, anthracite), which echoes the blue ceramic bezel; alternatively, vegetable calf leather that ages toward golden hues mirroring the Sedna Gold, or burnished shell cordovan for warm chromatic contrast. For sports use, FKM rubber with waffle texture enhances 150m water resistance without aesthetic compromise.

Removing the original strap is straightforward: place the watch on a soft surface, locate the two lug pins (spring bar) on the sides of the case at 3 and 9 o'clock. Use a spring bar tool or a thin flat end to gently compress the internal spring, which releases the pin from the lug. Insert the new 20mm strap by aligning the ends to the pins, ensuring compression is symmetrical. Casati Milano offers professional strap change service with consultation on available leather options.

Absolutely. The Omega 220.50.41.21.02.002 uses standard 20mm lugs, compatible with any strap on the market of the same width. Artisanal straps from milanostraps.it are crafted to 20mm specifications, tested for fit and available with precision terminals, without lateral play. Artisanal quality guarantees durability exceeding 36 months with regular maintenance.

A quality artisanal vegetable leather strap lasts 3–5 years with moderate daily use (4–6 days weekly, non-humid environments). Shell cordovan, thanks to leather density, reaches 5–7 years. Lifespan depends on rotation (ideally alternate 2–3 straps), ambient humidity, direct sun exposure, and frequency of baths and showers. Casati Milano provides an 18-month warranty and regeneration services for controlled aging.
