Frequently asked questions
What is the exact lug width of the Omega Constellation 1165.77.00?
The Omega Constellation 1165.77.00 has a lug width of 18mm. This measurement represents the distance between the two lugs where the strap attaches to the case. It is important to measure it correctly by positioning a millimeter ruler perpendicularly on the lug shoulder to avoid errors when purchasing a replacement strap.
What strap materials are best suited for the Constellation 1165.77.00 in white gold?
For the Constellation 1165.77.00 in white gold, we recommend acclimated alligator leather with regular grain (best aesthetic compatibility with the pale metal), vegetable-tanned calf leather that develops a golden patina over time, or quality rubber for sports use. We advise against overly casual materials such as NATO straps, which do not harmonize with the classic and refined identity of this women's model.
How do you change the strap on an Omega Constellation 1165.77.00?
Changing the strap on the Constellation 1165.77.00 is performed using special tools for extracting the spring bars. It is advisable to consult a professional watchmaker or the Casati Milano atelier to avoid damage to the sapphire crystal and the delicate lugs of the white gold case. The procedure requires precision, especially on a valuable case.
Is a generic 18mm aftermarket strap compatible with the Constellation 1165.77.00?
Yes, any strap with an 18mm lug width is physically compatible with the Constellation 1165.77.00. However, we recommend high-quality straps (alligator, calf leather, technical rubber) to respect the jewelry status of the watch. Casati Milano artisanal straps guarantee precise measurements and finishes that fully enhance the white gold case.
How long does a leather strap last on the Constellation 1165.77.00 in daily use?
A high-quality leather strap (alligator or vegetable-tanned calf leather) typically lasts 18-24 months with daily wear. Durability depends on environmental humidity, frequency of use, and care (periodic cleaning, protection from prolonged water and moisture exposure). Casati Milano straps include an 18-month warranty, with the option of revision or replacement of worn components after this period.
