Frequently asked questions

What is the lug width of the Omega Constellation 123.55.27.60.55.006?

The Omega Constellation 123.55.27.60.55.006 features an 18mm lug width. This dimension represents the distance measured between the inner flanges of the case, and is critical to ensure proper strap attachment without slippage or excessive tension.

What is the best strap material for the Constellation 123.55.27.60.55.006 in rose gold?

Dark brown alligator (cognac or chocolate shades) represents the most elegant choice, creating a balanced aesthetic dialogue with rose gold. Alternatively, vegetable-tanned calf offers rich patinas full of character, while shell cordovan creates particularly sophisticated glossy and deep effects.

How do I change the strap on my Omega Constellation 123.55.27.60.55.006?

Strap replacement requires the use of a spring bar tool to remove the elastic pins that secure the strap to the lugs. It is advisable to proceed with caution, preferably on a soft surface, to avoid scratching the rose gold case. For those who prefer professional assistance, the Casati Milano atelier offers a quick replacement service.

Can I use aftermarket straps compatible with my Constellation 123.55.27.60.55.006?

Yes, provided the strap is designed for an 18mm lug width. On milanostraps.it you will find compatible straps in various materials (alligator, calf, rubber, NATO), customizable in size, initials and stitching thread, with artisanal quality guarantee.

How long does a leather strap last on the Omega Constellation 123.55.27.60.55.006?

A premium leather strap (alligator, calf, shell cordovan) can last 3-5 years with daily wear, developing a characteristic patina over time.
