Strap for Constellation Co-Axial 44 Chronograph Double Eagle Four Counters Stainless Steel / Black / Rubber

The Omega Constellation 121.32.44.52.01.001 is fitted with a standard 20mm lug width. This dimension is perfectly proportioned to the 44mm case and offers compatibility with a wide range of aftermarket straps available on the market.

It depends on use and context. For formal occasions, black or burgundy alligator leather conveys elegance. For daily wear, vegetable-tanned calf offers comfort and develops a noble patina over time. For sports use, vulcanized rubber or canvas nato straps guarantee resistance. Shell cordovan represents the ideal compromise between durability and refinement.

For safe replacement, you will need a dedicated tool (spring bar tool). Remove the spring bars that secure the current strap to the case lugs, then insert the spring bars into the new strap and secure them to the same attachment points. If you are not experienced, Casati Milano offers personalized replacement service by appointment.

Yes, all 20mm straps available on Milano Straps are fully compatible with your Constellation. On the website you will find a dedicated section for 20mm straps. You can choose from materials (alligator, calf, nato, rubber) and customize the dimensions, initials, and stitching thread color.

Durability depends on the material, tanning, and use. Vegetable-tanned calf typically lasts 5-7 years with daily wear. Alligator and shell cordovan, thanks to their greater natural density, easily reach 8-12 years. Vulcanized rubber lasts 6-10 years. Casati Milano guarantees 18 months on all made-to-measure straps created in the atelier.
