Frequently asked questions
What is the lug width of the Omega Constellation 123.20.27.60.52.001?
The lug width is precisely 16mm. This measurement is specific to the Constellation ladies' model in 27mm format and is essential for aftermarket strap compatibility. You can verify it by measuring directly between the case lugs with a digital calliper.
Which strap material is most suitable for the Constellation 123.20.27.60.52.001?
Alligator is the most elegant choice, particularly in dark shades (black, brown, burgundy). Vegetable-tanned calf leather offers versatility and develops a natural patina over time. For extreme durability and deep lustre, shell cordovan from the horse's back is unparalleled. All these materials are available in 16mm at Milano Straps.
How do I change the strap on the Constellation 123.20.27.60.52.001?
The Constellation uses direct lugs with spring bars. Obtain a spring bar tool and a protected work surface. Gently compress the spring mechanism towards the case interior, remove the old lug, and insert the new one using the same principle. If you're not experienced, the Casati Milano atelier can perform the change during a consultation.
Can I use compatible aftermarket straps with my Omega Constellation 123.20.27.60.52.001?
Yes, absolutely. Any quality 16mm strap is compatible with the Constellation lugs. Milano Straps' straps are tested for perfect fit without mechanical play. Your choice of material, colour, and finish is entirely free according to your aesthetic preference and usage context.
How long does a leather strap last on this watch?
Durability depends on the material: alligator and vegetable-tanned calf guarantee 3-5 years with daily wear and regular maintenance (cleaning every six months). Shell cordovan lasts 10-15 years. Factors reducing lifespan are prolonged sun exposure, constant humidity, and salty perspiration. A well-maintained strap, gently dried after water contact, ages beautifully.
