Strap for Constellation Co-Axial 35 Stainless Steel / Diamond / MOP Supernova / Alligator

The lug width is 20 millimeters. This dimension is specific to the 35mm case model and has been calculated by Omega to maintain perfect visual proportions between case and strap. To verify compatibility, measure the space between the lugs with a digital caliper: it must be exactly 20mm from inside to inside.

For this model, a cognac brown alligator or vegetable-tanned calf leather represent the most sophisticated choices, as the natural grain perfectly complements the brushed finish of the case. If you seek versatility and daily durability, a glossy black calf or navy blue NATO strap are excellent alternatives. Your choice depends on your primary context of use and personal color palette.

To change the strap, remove the watch from your wrist and position it case-side up. Locate the two pins that pass through the lugs (one on each side): using a spring bar tool or a toothpick, gently push the pin toward the center of the case to compress the internal spring, then remove the old strap. Align the holes of the new strap with the lugs and reinsert the pins. Verify that both sides are securely fastened.

Yes, you can use any strap with a compatible 20mm lug width. Quality aftermarket straps, such as those in alligator or vegetable-tanned calf leather, often offer more customization than original Omega bracelets. Ensure that the strap is made with tanned leather and that the pins are stainless steel to prevent corrosion.

A quality leather strap, especially if made with vegetable tanning, typically lasts 3-5 years with daily wear, depending on sun exposure, humidity, and frequency of use. Genuine alligator tends to last longer than calf leather. To extend the life of your strap, avoid prolonged water immersion, protect it from direct sunlight, and consider rotating multiple straps to reduce concentrated wear.
