Strap for Constellation Co-Axial 35 Yellow Gold / Diamond / Champagne

The lug width is 20mm. It is measured from inside to inside between the two lugs of the case where the strap attaches. This thickness is standard for the 35mm Constellation and ensures a precise fit without excessive play.

Red or warm brown alligator is the classic choice that does not compromise the elegance of the case. For daily wear, vegetable-tanned brown calf with natural patina is ideal. Bordeaux shell cordovan is extraordinary if you desire a strap that evolves over time with chromatic depth.

Use a spring bar tool to gently remove the spring bars from the sides of the case. Extract the old strap, insert the new one by correctly aligning the holes, then re-engage the spring bars to the case lugs. The procedure requires care: 18k yellow gold is soft and prone to scratching.

Milanostraps offers customizable 20mm straps in Italian leather (alligator, calf, shell cordovan) with steel or gold deployante. Casati Milano creates bespoke made-to-measure straps with an 18-month warranty, ideal for those wanting a perfect match with the case.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) on a regularly worn watch lasts 3-5 years before showing signs of significant wear. Durability depends on sun exposure, humidity, and frequency of use. The Constellation 123.55.35.20.58.001, being in gold, deserves premium straps that age elegantly.
