Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Stainless Steel / Sedna Gold / Grey - Diamond / Bracelet

The lug width of the Omega Seamaster Aqua Terra 220.20.34.20.59.001 is 16 mm. This measurement is specific to the 34 mm models in the Aqua Terra collection and does not correspond to more common standards such as 18 mm or 20 mm. To verify the compatibility of a strap, measure the internal distance between the two lugs of the case with a ruler: it must correspond exactly to 16 mm.

To enhance the elegance of Sedna Gold paired with stainless steel, we recommend a strap in dark brown or black alligator leather: the natural texture of the scales emphasizes the lustre of rose gold without competing visually. Alternatively, a coarse-grained calf leather in cognac or pearl grey offers versatility with a patina that develops over time. For casual use, a natural rubber strap maintains sportiness and water resistance. All available in 16 mm at Milano Straps.

To change the strap, obtain a spring bar tool (instrument with a rounded tip). Position the watch face down and insert the tip of the tool into the small hole located in the middle of the spring bar on the side of the lug. Gently push upward to relax the internal spring, then remove the old strap. Repeat the operation on the other side. To install the new strap, align the two ends to the spring bars and, while holding the spring bar in tension, slide the strap into position. Verify that the strap is securely held on both sides.

Yes, any strap with a lug width of 16 mm is compatible with the Omega Aqua Terra 220.20.34.20.59.001, provided that the ends of the strap are slightly tapered to fit correctly on the case lugs. High-quality artisanal straps offer advantages such as custom stitching, leather selection, and personalized finishes. Milano Straps offers a collection of 16 mm straps in alligator, calf leather, and rubber specifically selected for your Omega model.

The lifespan of a leather strap depends on usage, quality of craftsmanship, and climate. A high-quality alligator strap, with artisanal stitching, has an average lifespan of 5-7 years of daily use, although patina begins to develop after the first few months. Calf leather is more subject to wear and may require replacement every 3-5 years depending on frequency and exposure to moisture. Natural rubber, if of good quality, lasts 4-6 years. Casati Milano guarantees 18 months on its work and recommends storing the strap away from direct light and very dry environments to extend its life.
