The Omega Constellation 123.20.35.20.02.004 has a lug width of 22 mm, which is the distance between the case lugs where the strap attaches. This width is proportionate to the 35 mm case diameter and is standard for this reference family.
What type of strap is recommended for the Constellation 123.20.35.20.02.004?
For the Constellation 123.20.35.20.02.004 we recommend alligator in dark shades for maximum formal elegance, calf leather in grey or beige for modern and versatile contexts, or shell cordovan in bordeaux for those who appreciate the natural patina that develops over time.
How do you change the strap on the Constellation 123.20.35.20.02.004?
The strap is changed using a specific spring bar tool: position yourself on the lower lug, gently press the spring bar button to release the spring, and remove the strap. Repeat on the other side. Insert the new strap by aligning the ends with the lugs and press until you hear the locking click.
Are aftermarket straps compatible with the Omega Constellation 123.20.35.20.02.004?
Yes, any strap with a 22 mm lug width is compatible with the Constellation 123.20.35.20.02.004. Online you will find customizable artisanal leather straps (alligator, calf, shell cordovan) ready for shipment, or you can commission a custom strap from the Casati Milano atelier with 18 months warranty.
How long does a leather strap last on a Constellation?
A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily use, varying based on frequency of use, humidity, and care. Artisanal vegetable-tanned straps develop natural patina and can last longer if maintained regularly.
