Frequently asked questions

What is the lug width of the Omega LadyMatic 425.37.34.20.57.001?

The Omega LadyMatic 425.37.34.20.57.001 has a lug width of 18mm. This width is specific to the model and is measured perpendicularly between the two lugs on the case. Any replacement strap must have exactly 18mm width to fit perfectly without play or excessive tension.

What material is most suitable for an Omega LadyMatic 34mm strap?

Alligator represents the most aesthetically coherent choice, thanks to its regular geometric grain that reflects the technical precision of the movement. Calf leather constitutes a more discreet and versatile alternative for everyday wear. Natural rubber offers ergonomic comfort and practicality. For long-term investments, vegetable tanning and shell cordovan develop a unique patina over time.

How do you change the strap on the Omega LadyMatic 425.37.34.20.57.001?

Strap replacement requires the use of specialized tools, as the LadyMatic's lugs are integrated into the case. It is recommended to entrust the work to a professional watchmaker who has a precision spring bar tool to avoid damaging the case. Casati Milano atelier offers strap replacement services with warranty on work performed.

Which aftermarket straps are compatible with reference 425.37.34.20.57.001?

All straps with 18mm lug width are compatible with the LadyMatic 425.37.34.20.57.001. Milano Straps offers a dedicated collection of 18mm straps customizable in leather, color, initials and thread stitching, with fast delivery and the possibility of bespoke commissions at Casati Milano atelier.

How long does a leather strap last on an Omega watch?

The durability of a leather strap depends on the material and usage. Quality calf leather lasts 3-5 years with ordinary care. Alligator and shell cordovan can exceed 7-10 years thanks to a more robust fibrous structure. Vegetable tanning ages naturally, developing characteristic patina. Milano Straps guarantees 18 months on all bespoke straps made at Casati Milano.
