Strap for Constellation Co-Axial 38 Stainless Steel / Black

The lug width of the Constellation 38mm 123.10.38.21.01.002 is 20mm. This is the distance between the pins that attach the strap to the case. Measuring correctly with a caliper is essential before purchasing a compatible strap.

For the Constellation 123.10.38.21.01.002 we recommend alligator straps for formal wear, vegetable-tanned calf leather to develop patina over time, or silk NATO for maximum versatility. The stainless steel case pairs well with dark leathers (black, brown, burgundy) and fittings in precious metal or titanium.

Remove the pins locking the strap using a gentle spring bar tool, available from specialist retailers. The tool has two tips that press on both sides of the pin to release the internal spring. Proceed carefully to avoid scratching the steel around the case lugs.

Technically yes, provided it has a 20mm lug width and compatible thickness. However, we recommend certified quality artisanal straps to enhance your watch: noble leathers and finishes consistent with Omega standards guarantee longevity and superior aesthetics compared to generic budget solutions.

A quality leather strap, under normal use (5-6 days per week), lasts 3-5 years. Longevity depends on ambient humidity, frequency of water exposure, and tanning quality. Vegetable tanning ages elegantly, while chemically treated leathers tend to harden. An 18-month warranty is standard for reliable craftsmen.
