Frequently asked questions

What is the lug width of the Omega LadyMatic 425.22.34.20.55.003?

The lug width of the LadyMatic 425.22.34.20.55.003 is 16mm. This measurement represents the distance between the two lugs and is essential for purchasing a compatible strap. It is advisable to verify the measurement with a caliper before ordering to ensure proper fit.

What is the best strap material for the LadyMatic 425.22.34.20.55.003?

Alligator is the most refined choice for the LadyMatic, as its scale texture reflects light in a manner consistent with the mother-of-pearl dial. Alternatively, vegetable-tanned calf offers a patina that evolves over time. For summer practicality, a dark grey NATO or silk fabric maintains elegance while reducing maintenance.

How do you change the strap on the Omega LadyMatic 425.22.34.20.55.003?

The strap is changed using a spring bar tool, available online at low cost. Position the tip of the tool in the small slot beneath the lug, gently push upward to release the spring, and slide the old strap outward. Then insert the new strap, ensuring the spring is correctly seated. The operation takes approximately 2-3 minutes per side.

Is a 16mm aftermarket strap compatible with the LadyMatic 425.22.34.20.55.003?

Yes, any strap with a certified lug width of 16mm is compatible with the LadyMatic 425.22.34.20.55.003. Milano Straps offers a complete collection of 16mm customizable straps in fine leathers such as alligator and calf, with 18-month warranty and bespoke options available at the Casati Milano atelier.

How long does a leather strap last on the LadyMatic?

The lifespan depends on the material and usage. A quality alligator strap, worn daily, has a lifespan of 5-7 years before requiring replacement, thanks to the natural resistance of the scales. Calf offers similar durability but with a visible patina that develops progressively. NATO and fabric straps have greater longevity (8-10 years) but maintain lower elasticity. Milano Straps provides an 18-month warranty against manufacturing defects.
