Frequently asked questions

What is the lug width of the Omega LadyMatic 425.60.34.20.51.001?

The lug width of the LadyMatic 425.60.34.20.51.001 is 14mm. This is a rare dimension in the watchmaking landscape, making strap compatibility selective and requiring a conscious choice among available aftermarket options. The measurement should be taken from the inner point of the upper lug to the inner point of the lower lug.

Which strap is ideal for the Omega LadyMatic in rose gold 34mm?

Alligator represents the most refined solution, with a subtle texture that enhances rose gold without competing with it. For daily wear, vegetable-tanned calf develops a natural patina over time. Shell cordovan offers exceptional durability and intrinsic lustre. Avoid NATO and rubber straps: they would diminish the timepiece's sophistication. A deployant clasp ensures secure closure and comfort.

How do I change the strap on this LadyMatic?

The change requires a spring bar tool or a specialized tool to remove the integrated lug from the case. On models with special integrated lugs like the 425.60.34.20.51.001, it is highly recommended to entrust the operation to a competent watchmaker or contact the Casati Milano atelier directly for professional intervention without risk of damage to the rose gold case.

Are there aftermarket straps compatible with the 425.60.34.20.51.001?

Yes. Milano Straps offers a dedicated collection of 14mm compatible straps, ready for shipment and customizable in sizes, initials and thread colour. For a complete bespoke experience, the Casati Milano atelier creates made-to-measure straps with personal selection of leathers, updates via WhatsApp and 18-month warranty.

How long does a leather strap last on a watch like the LadyMatic?

Durability depends on the material and usage. Alligator and shell cordovan, if properly maintained, guarantee 5-7 years of daily wear before requiring replacement. Vegetable-tanned calf has a similar lifespan, with the advantage that the natural patina tells the story of wear. Casati Milano warranty is 18 months, with the possibility of maintenance interventions. Exposure to excessive heat and humidity reduces longevity.
