Frequently asked questions

What is the lug width of the Omega LadyMatic 425.22.34.20.55.002?

The Omega LadyMatic 425.22.34.20.55.002 features an 18mm lug width. This specific dimension requires custom straps; standard 20mm or 16mm models will not fit the lugs without structural stress that would compromise the case architecture.

What is the best strap for the Omega LadyMatic 425.22.34.20.55.002?

For the mother-of-pearl dial and yellow gold accents, we recommend an ivory alligator or fine-grained calf leather in cream tones. Alligator, with its natural texture and elegant drape, emphasizes the iridescence of the case, while vegetable-tanned calf offers chromatic versatility and a patina that ages nobly over time.

How do you change the strap on the Omega LadyMatic 425.22.34.20.55.002?

The replacement requires a delicate operation due to the case's reduced proportions (34mm). It is essential to use professional tools (a spring bar tool specifically designed for narrow lugs) and, preferably, consult a qualified watchmaker. Milano Straps also provides this service at the Casati Milano atelier with pre-service technical consultation.

Are aftermarket straps compatible with the 425.22.34.20.55.002?

Yes, provided they are made with an 18mm lug width and thickness that does not create stress on the case. Compatibility is not merely dimensional: the strap must respect the aesthetic balance of the case (34mm), avoiding excessive thickness that would alter the original proportions. Milano Straps personalizes straps certified for this model.

How long does a leather strap last on the Omega LadyMatic?

An artisanal alligator or calf leather strap lasts 3-5 years with daily use, with the option of replacing the deployante buckle. Durability depends on exposure to sweat, humidity, and cleaning frequency. Casati Milano provides an 18-month warranty on craftsmanship and offers guidance on preventative leather maintenance.
