Frequently asked questions
What is the correct lug width for the Omega De Ville 423.13.37.50.01.001?
The Omega De Ville 423.13.37.50.01.001 has a lug width of 19mm, measured inside the lugs from one side to the other, excluding the case material. This dimension is essential to ensure a perfect strap fit without lateral play or friction against the case edges.
Which strap material is most suitable for this De Ville model?
Vegetable-tanned alligator is the noble choice for this dress watch, thanks to its fine grain that does not visually compete with the case details. Alternatively, shell cordovan offers constructive rigidity and a glossy appearance that elegantly reflects light, while premium European calf guarantees natural flexibility and sophisticated aesthetics.
How do you change the strap on an Omega with integrated lugs?
Straps for the Omega De Ville 423.13.37.50.01.001 connect to the case lugs through removable bayonet or push-fit lugs. Simply apply light pressure to extract the lug from the lug hole, detach the old strap, and insert the new one. The operation takes just seconds and requires no specialized tools, except possibly a magnifying glass.
Are there reliable aftermarket straps compatible with this Omega?
Yes, all straps with 19mm lug width are compatible with the Omega De Ville 423.13.37.50.01.001. Milano Straps artisanal straps are customized and tested to guarantee a perfect fit, using premium leathers such as alligator, shell cordovan, and calf, with professional finishes in satin or polished steel.
How long does an artisanal leather strap last on a daily-wear watch?
A quality leather strap, with vegetable tanning and professional stitching, has an average lifespan of 3–5 years with daily use, provided it is dried regularly and prolonged moisture exposure is avoided. Shell cordovan, more robust, can last up to 7–10 years. Milano Straps straps include an 18-month warranty and can be refurbished or replaced at the Casati Milano atelier.
