What I'm asked about the Omega LadyMatic 425.27.34.20.55.004
What strap size does the Omega LadyMatic 425.27.34.20.55.004 take?
The Omega LadyMatic 425.27.34.20.55.004 needs 18 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Omega LadyMatic 425.27.34.20.55.004 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Omega LadyMatic 425.27.34.20.55.004?
Yes, in 18 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Omega LadyMatic 425.27.34.20.55.004?
A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What is the best strap for the Omega LadyMatic 425.27.34.20.55.004?
To enhance the mother-of-pearl dial and Sedna Gold, we recommend alligator in cognac or black tones, or dark shell cordovan. These materials respect the proportions of the 34 mm case and complement the luminosity of the mother-of-pearl.
Is an aftermarket strap compatible with the 425.27.34.20.55.004?
Yes, any strap with an 18 mm lug width is compatible. However, we recommend artisan straps that respect the proportions of the 34 mm case and the aesthetic profile of the mother-of-pearl, to avoid altering the visual balance of the piece.
How long does a leather strap last on an Omega Ladymatic?
A premium leather strap (alligator or shell cordovan) lasts an average of 3-5 years with regular use and proper maintenance. Prolonged exposure to humidity, direct sunlight, and perspiration accelerates aging. Casati Milano artisan straps offer an 18-month warranty and require seasonal maintenance to preserve the patina.
