Strap for Constellation Co-Axial 35 Stainless Steel / Yellow Gold / Silver

The lug width of the Constellation 123.20.35.20.02.002 is 20 mm. This measurement represents the distance between the case lugs and determines strap compatibility. It measures the width of the space between the outer edges of the two lugs without including the width of the case itself.

For the two-tone Constellation, a cognac brown alligator strap or vegetable-tanned calf leather represent the most harmonious choices. Burgundy shell cordovan offers luxurious texture, while a navy blue NATO strap ensures versatility. The choice depends on intended use: elegant for formal occasions, casual for everyday wear.

Use a dedicated spring bar tool to compress the spring bar positioned vertically in the case lugs. Release one end of the bar, remove the old strap, and repeat the operation on the other side. Insert the new 20mm strap into the same holes, ensuring the spring bar clicks firmly into position. If you are unsure, entrust the task to a professional watchmaker.

Yes, any strap with a 20 mm lug width is compatible with the Constellation 123.20.35.20.02.002. A quality artisanal strap guarantees not only perfect compatibility but also aesthetic tailoring: the selected leathers, precise stitching, and elevated finishes convey the value of the Omega case to the strap.

A quality leather strap (alligator, calf, shell cordovan) maintains structural integrity for 3-5 years with moderate daily use. Lifespan depends on climate, humidity, and maintenance: vegetable-tanned leather ages gracefully, while shell cordovan, due to its natural density, lasts longer. Periodic replacement is part of the ownership experience of a fine timepiece.
