Frequently asked questions
What is the lug width of the Omega Constellation 131.50.29.20.52.001?
The lug width of reference 131.50.29.20.52.001 is 18mm. This width is standard for the 29mm version of the Constellation and is essential for selecting compatible straps. Always verify the complete reference number, as other Constellation versions may have <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">different lug widths</a>.
Which strap pairs best with the Omega Constellation 131.50.29.20.52.001 in Sedna Gold?
For Sedna Gold we recommend straps in tortora alligator or taupe brown crocodile, which enhance the warm tone of rose gold without competing visually. An elegant alternative: vegetable-tanned calf leather in cognac colour, which develops a golden patina over time, creating a synergistic colour effect with the case. Avoid cold colours (dark blue, grey) that contrast with the red undertone of Sedna Gold.
How do you change the strap on an Omega Constellation 29mm?
The Omega Constellation 131.50.29.20.52.001 uses standard 18mm spring bars. To change the strap: remove the original bracelet using a spring bar tool, insert the spring bars of the new strap into the case lugs, verify the lock. If you are not experienced, the Casati Milano atelier offers replacement service with supervision and leak testing. Never force the spring bars to avoid damage to the case lugs.
Are aftermarket straps really compatible with the 131.50.29.20.52.001?
Yes, provided the lug width is certified 18mm and the spring bars are standard. However, construction quality is decisive: poor quality leather ages poorly and transfers moisture to the case. Casati Milano's handcrafted straps, made with selected leathers and artisanal stitching, respect the dimensional tolerances of the Omega case and guarantee superior comfort and longevity compared to industrial products.
How long does a natural leather strap last on a Constellation 29mm worn daily?
A vegetable-tanned leather strap lasts 3-5 years with daily wear, developing an aesthetic patina that increases its appeal. Durability depends on: frequency of wear, environmental humidity, maintenance (periodic cleaning, drying), type of leather. Alligator and shell cordovan resist longer. Casati Milano atelier guarantees 18 months from first purchase and offers strap regeneration and renewal services.
