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

The Omega Aqua Terra 231.10.39.60.02.001 has a lug width of 20 millimetres. This dimension is precise and non-negotiable to maintain correct proportions between case and strap. Measure the space between the lugs on the case to verify this specification before ordering a replacement strap.

The best strap depends on use and personal style. Alligator offers sophistication and visually complements the teak dial; vegetable-tanned calf ensures durability and austerity; rubber is ideal for aquatic environments. The 231.10.39.60.02.001 accepts all these options with aesthetic coherence, always maintaining the 20mm lug width.

The change is made via spring bars (lugs) that connect the strap to the case. Insert a thin tool (such as a spring bar tool) under the bar, apply gentle outward pressure until it releases, then remove the old strap. Repeat on the other side. Insert the new 20mm strap by aligning the holes with the lugs, press gently until it clicks. If unsure, contact an official Omega service centre.

Yes, provided the strap has a lug width of 20 millimetres and is made from quality materials. Handcrafted straps from Milano Straps are specifically designed for this size and maintain the aesthetic standards of the 231.10.39.60.02.001, with customisations in leather, colour and stitching.

The lifespan of a leather strap is 3–5 years with daily use, depending on the leather chosen and maintenance. Alligator and vegetable-tanned calf age gracefully, developing patina; rubber lasts longer but requires periodic cleaning. Casati Milano straps come with an 18-month warranty and can be refurbished or replaced at the atelier.
