Strap for LadyMatic Co-Axial 34 Stainless Steel / Diamond / Black

The Omega LadyMatic 425.38.34.20.51.001 has a lug width of 18 mm. This is the internal space between the two case lugs where the strap is attached. The 18 mm measurement is specific to this model and is essential for a correct fit without visual overload or compression on the wrist.

Alligator remains the most sophisticated choice thanks to its natural grain and the patina that develops over time. Vegetable-tanned calf leather offers a more dynamic texture and a wider color range. For those seeking a strap that ages beautifully, Shell Cordovan is ideal for its ability to develop a unique mirror-like patina over time.

Use a digital caliper to measure the internal space between the two case lugs. Position the measuring tool transversely between the two attachment points. For the Ladymatic, you should obtain exactly 18 mm. If you have any doubts, contact the Casati Milano atelier to verify compatibility before purchase.

The durability of a leather strap depends on the material and usage. Premium quality alligator or calf leather, with proper care, lasts 3-5 years of daily use. Shell Cordovan, due to its denser structure, can last 5-7 years while maintaining structural integrity. To maintain the strap, avoid prolonged direct moisture and apply specific conditioner every 6-12 months.
