Strap for Constellation Master Chronometer 36 Stainless Steel / Sedna / Silver - Diamond / Bracelet

The lug width of the Omega Constellation 131.20.36.20.52.001 is 22 millimetres. This measurement is essential for selecting compatible straps: any strap purchased must have a width of 22mm to ensure precise coupling between the internal fixing pins of the case. A measurement error will result in unusable straps.

For the Constellation 131.20.36.20.52.001, alligator represents the most balanced solution, as the regular grain enhances the harmonious proportions of the two-tone case. Shell cordovan is the choice for maximum longevity and visible ageing patina. Vegetable-tanned calf leather offers a good compromise between elegance and aesthetic character development over time. Natural rubber (FKM) is ideal for sports use or humid environments.

The strap is changed by extracting the fixing pins that connect the strap to the respective lugs on the case. You will need to use a dedicated pin remover tool or a small flat lever. Position the watch face-down on a soft surface, identify the access holes to the pins on the inside of the case, insert the tool and apply pressure outward until the pin is extracted. The new 22mm strap is inserted by aligning the eyelets with the lug holes and reinserting the pins with gentle pressure. We recommend having an expert guide you the first time.

All quality straps with a 22mm lug width are compatible with the Omega Constellation 131.20.36.20.52.001, regardless of manufacturer. It is essential to verify that the measurement is precise (21.9-22.1mm). On milanostraps.it a dedicated collection of 22mm straps is available in alligator, shell cordovan, calf leather and synthetic materials, all selected for aesthetic proportion and durability with this reference.

The lifespan of a natural leather strap depends on the specific material and frequency of use. An alligator or calf leather strap with moderate use (4-5 days per week) guarantees 2-3 years before visible wear. Shell cordovan, due to its superior density, extends the useful life up to 4-5 years. Accelerated wear occurs in high-humidity environments, frequent perspiration or prolonged direct sun exposure. Periodic maintenance (treatment with specific balms every 6 months) significantly extends the strap's longevity.
