Strap for Constellation Quartz 27 Brushed Stainless Steel / Black Supernova

The lug width of the Constellation 123.10.27.60.51.001 is 18mm. This is the dimension that determines strap compatibility: an 18mm strap fits perfectly into the lugs without lateral play. You can verify this measurement using a digital caliper positioned perpendicularly between the two lugs of the case.

For this reference we recommend alligator or vegetable-tanned calf leather. Alligator enhances the feminine sophistication of the model thanks to its natural grain and geometric texture. Calf offers excellent value for money and ages beautifully, developing a unique patina. For a more sporty approach, raw cotton NATO provides daily versatility while maintaining elegance.

Strap replacement is done via the lugs: position the watch face down, locate the metal spring bar that runs horizontally through the lug, and use a spring bar tool to gently lift the bar until it comes free. Once released, you can slide off the old strap and insert a new 18mm strap. Be careful not to lose the spring bar and ensure it is reinserted firmly in the opposite direction.

Yes, any 18mm strap is perfectly compatible with this reference. Artisanal aftermarket straps in alligator, calf, and shell cordovan function identically to original Omega straps, with the added benefit of customization options (initials, custom stitching thread) and construction quality often superior thanks to bespoke crafting.

A quality leather strap, such as alligator or vegetable-tanned calf, lasts an average of 3-5 years with moderate daily use. Durability depends on humidity, body perspiration, and maintenance. A Casati Milano strap is covered by an 18-month warranty and can be refurbished or replaced at reasonable cost. Leather ages naturally, developing a patina that many consider desirable rather than a flaw.
