Strap for Seamaster Aqua Terra 150M Quartz 38.5 Stainless Steel / Silver / Bracelet

The Omega Aqua Terra 231.10.39.61.02.001 is equipped with a 20mm lug width. This measurement requires a strap with a 20mm lug width to ensure a precise and secure fit. The horizontal spring bars must seat perfectly in the available space under the case, without excessive play or instability.

It depends on the intended use. For formal elegance, alligator with vegetable tanning or matt shell cordovan represent the most refined choices. For frequent sporty wear, woven nylon NATO or rubber are unbeatable. Calfskin is the versatile compromise—warm and durable—suitable for transitions between different contexts.

Gently remove the watch from your wrist. Use a spring bar tool (a cross-shaped instrument with flat tips) to push inward one of the spring bars until it releases from the attachment hole. Remove the old strap. Position the new strap aligned with the holes and reinsert the spring bar. Repeat on the other side. Never force; the mechanism should snap naturally.

Yes, any 20mm strap is compatible with the 231.10.39.61.02.001, provided the lug width is indeed 20mm and the thickness does not exceed the available space under the case. Verify that the buckle or deployant clasp does not cause cracks or rubbing on the bezel.

Durability varies based on intensity of use, climate, and leather quality. An alligator strap with vegetable tanning typically lasts 3–5 years with daily wear; calfskin tends to last 2–4 years; shell cordovan can exceed 5–6 years thanks to its dense fibrous nature. Maintenance—drying after perspiration and annual conditioning—significantly extends strap life.
