Frequently asked questions
What is the exact lug width of the Omega Constellation 123.50.35.20.08.001?
The lug width is 20mm. This value represents the internal distance between the case lugs where the strap is inserted. It is essential to respect this dimension to ensure a perfect fit without play or friction.
Which strap materials are best suited for the 35mm yellow gold Constellation?
Alligator is the supreme choice for this model: its regular texture enhances the refinement of the precious case. Excellent alternatives include vegetable-tanned calf for noble patina, shell cordovan for chromatic depth, and rubber calf for resistant daily wear in humid conditions.
How do you change the strap on an Omega Constellation without risk to the case?
Remove the original bracelet's <a href="/pages/termine-glossario/deployante">deployment clasp</a> by gently pressing the locking pins. Use a strap-changing tool or blunt instrument to extract the suspension pins from the case. Insert the new strap by aligning the lugs to the case shoulders and resecure the pins. Avoid direct impacts on the yellow gold case to prevent denting.
Are Milano Straps aftermarket straps 100% compatible with reference 123.50.35.20.08.001?
Yes, 20mm straps are tested for precise compatibility with Constellation geometry. All Milano Straps products meet the rigorous tolerances required for this iconic model, guaranteeing a fit without gaps or unwanted protrusions.
How long does an artisanal leather strap last on a Constellation worn daily?
A strap in quality alligator or sartorial calf maintains structural integrity for 3-5 years of daily use, with positive aesthetic aging over time. Durability depends on humidity exposure, the number of temperature fluctuations, and the frequency of strap changes. Straps with rubber backing extend longevity in humid environments.
