Strap for LadyMatic Co-Axial 34 Stainless Steel / Diamond / Pink MOP / Bracelet

The Omega LadyMatic 425.35.34.20.57.001 features an 18mm lug width, a specific measurement characteristic of this model. The measurement must be taken on the inner part of the case, between the two lugs, using a digital caliper to ensure accuracy. Straps of different widths (16mm, 20mm) are not compatible: constructive precision is fundamental.

For the 425.35.34.20.57.001 model we recommend alligator for formality, vegetable-tanned calf leather for natural evolution over time, or shell cordovan for tactile contrast. For contemporary versatility, navy blue NATO or FKM rubber represent functional choices. All straps must be constructed specifically for the 18mm lug width.

Strap replacement requires the use of proper tools (spring bar removal tool, nylon hammer) to avoid damage to the case. The operation consists of removing the transverse pin that connects the strap to the lugs, positioning the new strap, and reinserting the pin. For precision and safety, the Casati Milano atelier provides complete support with detailed instructions via WhatsApp and the possibility of professional execution.

No, the 18mm lug width limits compatibility to female Omega models from the same generation. Other models may feature 16mm, 14mm, or larger lug widths. Always verify the lug width of your watch before purchasing straps, as constructive incompatibility makes mounting impossible.

An artisanal calf or alligator strap has an average lifespan of 5-7 years with regular use, varying according to frequency of use, sun exposure, and humidity. Vegetable tanning evolves naturally over time, creating an authentically personal patina. The Casati Milano atelier guarantees 18 months on all bespoke straps, with the possibility of regeneration or early replacement by evaluating wear conditions.
