Frequently asked questions

What is the exact lug width of the Omega Constellation 123.50.27.60.02.002?

The lug width of the Omega Constellation 123.50.27.60.02.002 is 20mm. This measurement represents the internal space between the two lateral lugs of the case and determines compatibility with any aftermarket strap. To verify it, position a ruler from the inside of one lug to the inside of the other in a straight line across the dial.

Which strap is recommended for this Constellation model?

For the 123.50.27.60.02.002, natural alligator straps (cognac or dark brown) are ideal for a formal look, or vegetable-tanned calf leather for authentic vintage character. Structured rubber with silk stitching is perfect if you seek contemporary versatility. The choice depends on your wearing context and the patina you wish to develop over time.

How do you change the strap on an Omega Constellation with integrated bracelet?

The integrated bracelet of the 123.50.27.60.02.002 requires specialized tools and technical expertise. The lug is not soldered like open bracelets, so the change must be done at a certified watchmaker or at the Casati Milano atelier, which offers custom solutions with 18-month warranty and direct WhatsApp updates.

All are tested and recommended for optimal proportions on this reference.

What is the average lifespan of a leather strap for this watch?

A high-quality leather strap, vegetable-tanned, maintains structural integrity for 3-5 years of regular wear. Lifespan depends on frequency of wear, exposure to moisture and natural fiber deterioration. Casati Milano straps come with 18-month warranty on manufacturing defects and offer professional reconditioning services.
