Strap for Constellation Co-Axial 38 Stainless Steel / Yellow Gold / Diamond / Silver

The lug width of the Omega Constellation 123.25.38.21.52.002 is 20 millimetres. This dimension is specific to this model and allows the use of any 20mm strap. To verify, measure with a digital calliper the distance between the two holes on the case where the original lug fits.

For the Constellation 123.25.38.21.52.002 we recommend alligator in chocolate brown or cognac tones, to harmonise with the two-tone case. Alternatively, vegetable-tanned calf leather that develops natural patina over time, or shell cordovan for durability and noble ageing. The choice depends on the context of use and the desired level of formality.

Obtain a spring bar tool (available online or at watch retailers). Remove the original strap by inserting the flat tip of the tool into the appropriate hole on the side of the spring, pushing to free one of the ends. Repeat on the other side. Remove the old strap and insert the new one by snapping the springs into the case slots, ensuring it is positioned correctly.

Yes, any 20mm strap is compatible with the Constellation 123.25.38.21.52.002. Always verify that the lug thickness is appropriate for the case (generally 3.5-4mm). Artisanal straps online are tested for this model and available with customisation options: adjustable sizes, engraved initials and choice of stitching thread.

An artisanal quality leather strap lasts on average 3-5 years in daily use, depending on exposure to moisture, heat and frequency of wear. Alligator and shell cordovan have longer lifespans (5-7 years). Maintenance is essential: avoid prolonged water immersion, gently dry after contact with moisture and apply specific conditioner every 6-12 months to preserve elasticity and lustre.
