Strap for Constellation Manhattan 25 Quartz Stainless Steel / Sedna Gold / Silver

The Constellation reference 131.20.25.60.02.001 has a lug width of 16mm. This dimension is essential for purchasing compatible straps. We recommend verifying it personally with a digital caliper or flexible ruler, measuring between the inner lugs of the case, to ensure maximum compatibility.

For the Constellation 131.20.25.60.02.001, we recommend premium alligator for formal occasions, thanks to its regular texture that amplifies the luminosity of Sedna gold. For daily wear, vegetable-tanned calf offers an excellent balance between elegance and durability, with a patina that evolves over time. Shell cordovan remains the choice for those seeking structural rigidity and natural lustre without compromise.

Changing the strap on the Constellation 131.20.25.60.02.001 requires a specific tool: a springbar tool. Position the watch on a stable surface, locate the springbars at the ends of the case, insert the tool under the springbar and lift gently until it springs out. Repeat on the other side, then insert the springbars of the new 16mm strap into the holes. If you are not experienced, we recommend contacting a qualified professional to avoid damaging the case.

Yes, any strap with a 16mm lug width is technically compatible. However, construction quality varies significantly between brands. We recommend choosing straps in alligator, calf or shell cordovan from specialist suppliers, which guarantee longevity and aesthetic consistency with the value of your Omega watch. Milano Straps offers handcrafted 16mm straps specifically tested on this model.

Durability depends on the material and usage. A premium quality alligator with vegetable tanning typically resists 3-5 years of daily wear before requiring replacement. Calf lasts 2-4 years. Shell cordovan, due to its greater rigidity, can reach 5-7 years. Exposure to moisture, heat and perspiration shortens these timeframes. Milano Straps provides an 18-month warranty on custom straps, covering manufacturing defects and workmanship faults.
