Frequently asked questions

What is the lug width of the Omega Constellation 123.25.27.60.55.008?

The lug width of the Constellation 123.25.27.60.55.008 is 20 mm. This technical specification is essential when selecting compatible straps: the distance between the two spring bars must be exactly 20 mm to ensure correct installation without any structural modifications to the watch.

What is the best strap for the Constellation 123.25.27.60.55.008?

For the Constellation 123.25.27.60.55.008 we recommend alligator in cognac or black tones, which enhances the mother-of-pearl dial and two-tone case. Vegetable-tanned calf leather in brown-hazelnut shades is a versatile alternative that develops golden patina over time. Cotton-silk NATO is ideal for summer or sports contexts.

How do you change the strap on the Omega Constellation 123.25.27.60.55.008?

Changing the strap requires a small tool called a spring bar tool to compress the elastic pins that secure the lugs to the case. Position the tool in the lateral grooves of the lug, gently compress the pin, and slide the strap outward. Repeat on the other side. To avoid scratches on the two-tone case, we recommend performing this operation on a soft surface.

Which aftermarket straps are compatible with the Constellation 123.25.27.60.55.008?

All straps with a 20 mm lug width are compatible with the Constellation 123.25.27.60.55.008. On milanostraps.it you will find a complete selection of 20 mm straps in various materials (alligator, calf, NATO, rubber), customizable in sizes, initials and stitching thread color.

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

The lifespan of a leather strap depends on the material and usage. Quality alligator and calf leather offer a longevity of 3-5 years with ordinary maintenance (regular cleaning, drying after moisture contact). Vegetable tanning develops patina that enhances the appearance over time. Casati Milano straps include an 18-month warranty against manufacturing defects.
