Frequently asked questions
What is the lug width of the Omega De Ville 434.20.34.20.02.001?
The lug width of the Omega De Ville 434.20.34.20.02.001 is 16 millimetres. This is the space between the two lugs of the case where the strap is inserted. It is essential to verify this dimension before purchasing an aftermarket strap, as an incompatible lug width would result in gaps or structural stress on the case.
What is the best strap material for the Omega De Ville 434.20.34.20.02.001?
Vegetable-tanned alligator is the choice most consistent with the De Ville's heritage identity, thanks to its structured texture and the patina that develops over time. For more everyday and versatile wear, vegetable-tanned calf offers a more contemporary look. Shell cordovan is ideal for those seeking maximum durability and a natural lustre that pairs beautifully with Sedna Gold.
How do I change the strap on my Omega De Ville 434.20.34.20.02.001?
The strap is replaced by removing the spring bar that connects the lugs to the case, using a dedicated tool. It is advisable to entrust this task to a professional watchmaker to avoid damage to the case or accidental loss of components. Casati Milano atelier offers installation services and personalized consulting by appointment.
Can I purchase an aftermarket strap compatible with my De Ville 434.20.34.20.02.001?
Yes, provided the lug width is exactly 16mm. Milano Straps offers a complete collection of 16mm straps compatible with the De Ville, customizable in material, colour, size and stitching thread. All straps are handcrafted from premium selected leather.
How long does a natural leather strap last on a watch like the Omega De Ville 434.20.34.20.02.001?
The lifespan depends on the material and usage. Alligator or shell cordovan in vegetable tanning, with regular maintenance, can last 3-5 years even with daily wear. A more delicate calf has a similar lifespan if protected from excessive moisture and perspiration. The warranty on Milano Straps handcrafted straps is 18 months against manufacturing defects.
