Frequently asked questions

What is the exact lug width of the Omega LadyMatic 425.67.34.20.55.009?

The lug width of the Omega LadyMatic 425.67.34.20.55.009 is 16 millimetres. This measurement must be verified by placing a calliper perpendicular to the two fixing holes of the case lugs. Only 16mm straps are compatible with this model.

What is the best strap for an Omega LadyMatic in Sedna Gold?

For a LadyMatic 425.67.34.20.55.009 in Sedna Gold, alligator represents the most refined choice, ideally in cognac or chocolate tones that amplify the warm golden character of the case. Vegetable-tanned calf leather is an elegant alternative for those desiring a patina that evolves over time. Avoid synthetics and rubber: the delicate proportions of the case require a strap that breathes elegance.

How do you change the strap on an Omega LadyMatic 425.67.34.20.55.009?

The LadyMatic 425.67.34.20.55.009 is equipped with spring lugs that allow strap changes without invasive tools. Position the watch on a soft surface and gently push the end of the connecting pin towards the inside of the case to release the old strap. Insert the new 16mm strap into the same spring until the safety click. Avoid forcing to prevent compromising the case integrity.
