Strap for Constellation Master Chronometer 36 Sedna / Silver / Bracelet

The Omega Constellation 131.50.36.20.02.001 has a lug width of 22 millimetres. This measurement is essential for selecting compatible straps. To verify it, measure the perpendicular distance between the two strap attachment points on the case, excluding the case shoulders. Any 22mm strap, regardless of material, is compatible with this model.

Certified quality alligator is the most natural choice, as the fine grain pattern of the scutes harmonizes beautifully with the griffée geometry of the case. Dark brown or dark brown-black alligator creates maximum formality. Alternatively, caramel or cognac calf amplifies the luminosity of Sedna gold, while burgundy shell cordovan offers formal elegance. For daily wear, vegetable-tanned calf develops a fascinating patina over time.

You will need specific tools: a spring bar tool (small lever extractor) and a soft surface on which to position the watch. Position the watch with the lug facing towards you, insert the flat end of the spring bar tool into the small groove of the spring bar that connects the lug to the strap, press gently to compress the spring, and the strap slides out. Repeat from the opposite lug. To install the new strap, align the holes with the lugs and press until the spring bar engages with a small click. Avoid applying excessive force to the case.

Yes, any strap with a 22mm lug width is compatible with the Omega Constellation 131.50.36.20.02.001. High-quality artisanal aftermarket straps in noble leathers such as alligator, calf, or shell cordovan not only maintain mechanical compatibility but often offer superior craftsmanship compared to standard straps. Ensure that the strap has holes compatible with the spring bars on the watch (typically 1.5-1.8mm diameter).

Durability depends on the leather, use, and maintenance. Certified quality alligator with vegetable tanning typically lasts 5-8 years in daily use, developing a fascinating patina over time. Calf offers similar durability (4-7 years) but is more sensitive to moisture and mechanical wear. Shell cordovan, due to its density, can last 8-10 years. Factors that shorten durability: prolonged water exposure, unwiped sweat, extreme temperatures, excessive strap flexing. Regular maintenance (drying after moisture contact, conditioning every 1-2 years with specific creams) significantly extends the strap's lifespan.
