Frequently asked questions
What is the lug width of the Omega Constellation 123.20.24.60.05.003?
The lug width measures 16mm. This measurement is crucial for selecting a compatible strap: an incorrect diameter compromises both aesthetics and wearing comfort. To verify with precision, remove the integrated bracelet and measure with a digital caliper the internal space between the lugs.
Which strap do you recommend for the Constellation 123.20.24.60.05.003 with mother-of-pearl dial?
Alligator in mahogany or burgundy tones represents the most coherent choice with the model's elegance. Stone grey smooth calf creates chromatic continuity with the dial. For informal proposals, champagne silk NATO or natural beige calf with subtle texture maintains sophistication without excess.
How do I change the strap on the Constellation 123.20.24.60.05.003?
The operation requires spring bar removers and a stable work surface. Position the watch on a soft pad, locate the lateral lugs, insert the remover into the upper slot of the spring until you feel the disengagement click, gently extract the spring. Repeat from the opposite side. Secure the new strap by reversing the procedure, verifying that the springs snap firmly into place.
Is there a certified aftermarket strap compatible with reference 123.20.24.60.05.003?
Yes. Any strap with a 16mm lug width is compatible. Our artisanal straps are made from selected leather (alligator, calf, shell cordovan) and available in various lug widths to suit your preferences. Order online from 16mm straps or contact Casati Milano atelier for bespoke consultation.
How long does a leather strap last on a daily-worn watch?
A quality artisanal alligator or calf strap, with proper maintenance (periodic cleaning and conditioning), maintains aesthetic and functional integrity for 3–5 years of daily wear. Constant exposure to sweat and humidity accelerates leather aging; rotating between multiple straps extends its lifespan. We offer an 18-month warranty on all our straps, covering manufacturing defects and material flaws.
