Frequently asked questions
What is the lug width of the Omega LadyMatic 425.65.34.20.55.013?
The lug width is 20mm, corresponding to the distance between the case lugs. This width is specific to Omega LadyMatic women's models and determines compatibility with aftermarket straps. To verify it, measure the internal distance between the two lugs with a digital caliper.
What is the best strap for the Omega LadyMatic 425.65.34.20.55.013?
For this white gold case, alligator remains the optimal choice: its natural grain elegantly complements the case's prestige. Shell cordovan offers sophisticated dark luster for formal occasions, while smooth calf guarantees daily versatility without aesthetic compromises.
How do you change the strap on the Omega LadyMatic 425.65.34.20.55.013?
The strap is replaced by removing the spring bars that connect the lugs to the case. Using a specific tool (spring bar tool), apply pressure on both sides of the lug to release the pins and detach the old strap. The new strap is inserted by seating the pins in their holes and verifying correct positioning.
Which aftermarket straps are compatible with the 425.65.34.20.55.013?
All straps with 20mm lug width are compatible. Consult Milano Straps' online collection, which offers certified selections for this width in fine leathers (alligator, shell cordovan, calf) customizable in color, thickness, and length.
How long does a leather strap last on an Omega LadyMatic?
A quality alligator or shell cordovan strap typically lasts 4-6 years with daily wear, varying based on frequency of use and climatic conditions. Casati Milano atelier offers an 18-month warranty on bespoke straps, covering manufacturing defects and premature stitching deterioration.
