Frequently asked questions

What is the lug width of the De Ville 4878.90.39?

The lug width of the Omega De Ville 4878.90.39 is 17mm, a rare and aristocratic measurement typical of the compact dress models of this generation. This dimension is proportioned to the compact 35mm diameter and ensures that the strap does not slip laterally on the wrist, maintaining the design harmony of the timepiece.

What strap material is recommended for the De Ville 4878.90.39?

European alligator is the primary choice to enhance the dress formality of the piece, thanks to its regular grain and pronounced scales. Shell cordovan is the contemplative alternative, with a caramelized patina that ages beautifully over time. For versatility, vegetable-tanned calf offers a smooth surface that maintains dignity even in less formal contexts.

How do you measure lug width for an Omega De Ville?

Position a ruler perpendicular to the case axis, from the inner edge of one lug to the inner edge of the opposite lug. For the De Ville 4878.90.39 the value must be exactly 17mm. It is essential to verify this measurement before purchasing aftermarket straps, as even one millimeter more or less would cause lateral binding or slippage.

Can I use an 18mm aftermarket strap on the De Ville 4878.90.39?

No, we advise against straps larger than 17mm. A single millimeter deviation would create lateral binding that would wear the inner lug of the steel case and compromise the proportioned aesthetics of the dress watch. For this timepiece, a strap constructed to the exact 17mm measurement is preferred, or choose from the options specifically designed for this reference.

How long does a leather strap last on an Omega De Ville?

Durability depends on frequency of use and material chosen. A vegetable-tanned European alligator typically lasts 5-7 years with regular use, developing a characteristic patina. Shell cordovan resists longer thanks to its fibrous structure, while thin calf may require replacement after 3-4 years if subjected to daily stress. The Casati Milano atelier provides an 18-month warranty on all custom straps.
