Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel - Ceramic / Turquoise / Rubber

The Omega Aqua Terra 220.32.38.20.03.001 has a lug width of 19mm. This measurement is determined by the proportion between the case diameter (38mm) and the lugs that secure the strap. Measuring the lug width is straightforward: place a ruler from the inside of the left lug to the inside of the right lug, in the strap attachment area.

For the Aqua Terra 38mm, it is advisable to choose between: black or blue alligator (maximum formal elegance), cognac vegetable-tanned calf (natural aesthetic aging), dark grey rubber (practicality for marine environments). The choice depends on the main use of the watch: formal prefers alligator, versatile prefers calf, sporty prefers rubber.

Changing the Aqua Terra strap requires a quality spring bar tool: insert the thin blade between the lug and the strap, compress the spring bar slightly to disengage it, remove the old strap. Reverse the procedure to install the new 19mm strap, ensuring that the spring bar is perfectly seated. If unsure, entrust the operation to a certified watchmaker.

Yes, any strap with a lug width of 19mm is compatible with the 220.32.38.20.03.001. High-quality artisanal straps (full grain leather, hand-stitched, custom deployant clasp) offer aesthetic and functional upgrades over the original strap while maintaining full compatibility with the case lugs.

The lifespan of a leather strap depends on usage and maintenance: with moderate exposure to moisture and perspiration, an alligator or calf strap lasts 3-5 years. Frequent exposure to water (chlorine, salt) reduces lifespan to 1-2 years. Regular cleaning with a damp cloth and immediate drying after water exposure significantly extend the strap's life.
