Strap for LadyMatic Co-Axial 34 Yellow Gold / Diamond / MOP / Bracelet

The lug width of the LadyMatic 425.65.34.20.55.002 is 20 millimetres. This dimension is specific to this model and is essential for choosing the correct strap. A strap with a different lug width will not fit properly into the integrated lugs on the case.

For the yellow gold LadyMatic we recommend premium alligator (with fine grain), vegetable-tanned calf in cognac or dark brown tones, or shell cordovan if you desire maximum refinement. These materials develop a patina that ages in parallel with the gold, creating aesthetic coherence over time. Avoid cold colours such as steel grey: yellow gold requires chromatic warmth.

To change the strap on the LadyMatic, remove the spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) to avoid damaging the gold case. Position the new strap (20mm lug width) into the attachments, ensuring that the spring bars click into place correctly. If you are not experienced, entrust the work to a professional watchmaker or contact Casati Milano for installation.

Yes, absolutely. An artisanal strap of superior quality in alligator, calf or shell cordovan is perfectly compatible with the LadyMatic 425.65.34.20.55.002, provided the lug width is 20mm. A custom strap crafted to fit your wrist and with careful selection of leather can even enhance the wearing experience of the watch compared to the standard factory strap.

Durability depends on the quality of the leather and use. Premium alligator or shell cordovan lasts 3-5 years with regular wear; vegetable-tanned calf 2-3 years. Factors such as sun exposure, perspiration, humidity and regular maintenance significantly impact longevity. Casati Milano offers an 18-month warranty on its artisanal straps and recommends periodic cleaning with a damp cloth and protection with specific creams.
