Strap for Seamaster Aqua Terra 150M Master Co-Axial 38.5 Stainless Steel / Blue / Bracelet

The Omega Aqua Terra 231.10.39.21.03.002 has a lug width of 18 mm. This width is measured as the distance between the two inner lugs of the case where the strap is inserted. Be sure to verify this measurement before purchasing an aftermarket strap to ensure perfect compatibility with the case lugs.

Alligator represents the most elegant choice for this model, with a subtle grain that does not compete with the teak motif of the dial. Shell cordovan offers natural durability and an almond patina; vegetable-tanned calf allows visible and characterful aging. For a sporty approach, a heavy cotton NATO emphasizes the terrestrial vocation of the collection.

Strap replacement is performed using the spring bars (removal bars) located beneath the case lugs. Use a dedicated tool or small screwdriver to gently press the lateral attachments, thus releasing the strap. Once removed, insert the new strap by aligning the holes with the lugs until the attachments click into position. This procedure takes only a few seconds and requires no special technical expertise.

Yes, any strap with an 18 mm lug width is compatible with the Aqua Terra 231.10.39.21.03.002. Milano Straps offers an extensive selection of straps in alligator, calf, shell cordovan and other materials, all ready for use on this model, customizable in sizes, colors and details such as initials and thread color.

A quality leather strap, made with vegetable tanning or shell cordovan, typically lasts between 3 and 5 years of daily wear, depending on environmental humidity, frequency of wear and maintenance. Leather fears prolonged water exposure and excessive perspiration. Proper drying after water exposure and light brushing every six months significantly extend the strap's lifespan, which also improves aesthetically through natural aging.
