Frequently asked questions
What is the exact lug width of the Omega LadyMatic 425.32.34.20.55.002?
The lug width of the Omega LadyMatic 425.32.34.20.55.002 is 20 mm. This width is constant along the entire length of the lugs and is determined by the distance between the pins that hold it in the case. It is essential to verify that any aftermarket strap has internal dimensions designed to accommodate 20 mm pins without excessive play.
Which strap is most suitable for the Omega LadyMatic 425.32.34.20.55.002?
For the LadyMatic 425.32.34.20.55.002, alligator represents the most elegant choice thanks to its regular texture and moderate grip, perfect for formal occasions. For everyday use, vegetable-tanned calf develops a splendid patina over time. Shell cordovan is ideal for maximum durability and evolving color brilliance. Compatible 20 mm straps are available on milanostraps.it in various leather and color options.
How do you change the strap on the Omega LadyMatic 425.32.34.20.55.002?
The strap is changed by gently extracting the pins from the lugs using a spring bar tool, the specific instrument equipped with a forked end that allows you to compress the small internal spring of the pins. This operation requires precision to avoid scratching the case. If you are unsure, it is advisable to contact a qualified watchmaker or the Casati Milano atelier for professional strap replacement.
Is the Omega LadyMatic 425.32.34.20.55.002 strap compatible with aftermarket straps?
Yes, the Omega LadyMatic 425.32.34.20.55.002 is fully compatible with quality aftermarket straps, provided they have a 20 mm lug width. On milanostraps.it you will find a complete selection of 20 mm straps certified for compatibility, customizable in leather, color, and stitching thread. The Casati Milano atelier can also create custom made-to-measure straps.
How long does a leather strap last on the Omega LadyMatic 425.32.34.20.55.002?
The lifespan of a leather strap depends on the quality of the tanning, usage, and care. A first-quality alligator or calf strap with vegetable tanning lasts an average of 3-5 years with daily use, developing a beautiful patina. Shell cordovan, being a denser leather, can last 7-10 years. Proper maintenance (occasional cleaning, drying after water contact, protection from direct heat sources) significantly extends the useful life. The Casati Milano warranty on made-to-measure straps is 18 months.
