Strap for Constellation Quartz 27 Polished Yellow Gold / Champagne Supernova

The Omega Constellation 123.50.27.60.58.002 features 18mm lugs, a critical measurement for aftermarket strap compatibility. This dimension (internal distance between one lug and the other) establishes the only acceptable standard for any replacement of the original bracelet.

For the Constellation 123.50.27.60.58.002, alligator represents the most elegant choice: its natural grain recalls vintage aesthetics and pairs perfectly with yellow gold. A sophisticated alternative is shell cordovan, which ages magnificently by developing an authentic patina.

Remove the bracelet using a spring bar removal tool, gently pushing the elastic pins downward. Extract the pins, remove the bracelet, insert the new pins into the 18mm strap, and reinsert everything into the case. Ensure the pins click securely at both ends.

Yes, any strap with 18mm lug width is compatible. Milano Straps offers a complete collection of handcrafted 18mm straps: alligator, vegetable-tanned calf, shell cordovan, NATO, and FKM rubber, customizable in sizes and details.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with moderate daily use, evolving aesthetically during the first year. Shell cordovan is more durable (7-10 years) thanks to fiber density. Milano Straps warranty covers the strap for 18 months against manufacturing defects.
