Frequently asked questions

What is the lug width of the Omega Constellation 123.20.27.60.05.001?

The lug width of the Constellation 123.20.27.60.05.001 is 16mm. This width is proportioned to the 27mm case and is the historic standard for ladies' Constellation models. Always measure the space between the two lugs before ordering a replacement strap to ensure perfect compatibility.

What is the best strap for the Omega Constellation 123.20.27.60.05.001?

Alligator is the most refined choice for this Constellation: the finest grain and the natural patina it develops over time enhance the complexity of the rose gold and steel case. For daily versatility, vegetable-tanned calf offers pronounced texture and durability. For practicality, natural rubber or FKM maintains elegance while ensuring water resistance.

How do you change the strap on an Omega Constellation 123.20.27.60.05.001?

The Constellation 123.20.27.60.05.001 features spring bars that insert into the two 16mm lateral lugs. Use a dedicated lug removal tool to avoid scratching the case: point the spring bar from above, push gently downward until it clicks, then remove the old strap. Insert the new strap from both ends simultaneously, ensuring the spring bars click correctly into both seats.

Can I use an aftermarket strap on an Omega Constellation 123.20.27.60.05.001?

Yes, any strap with a 16mm lug width is compatible with the Constellation 123.20.27.60.05.001. On milanostraps.it you will find a complete selection of artisanal 16mm straps in alligator, calf, shell cordovan and rubber, all tested for fit and comfort and customizable according to your preferences for color, thickness and stitching.

How long does a leather strap last on an Omega Constellation 123.20.27.60.05.001?

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years of daily wear, depending on climate, sun exposure and frequency of wear. Straps made by the Casati Milano atelier come with an 18-month warranty and develop a natural patina that improves aesthetics over time. To extend longevity, avoid prolonged salt water exposure and occasionally apply leather-specific conditioner.
