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

The lug width of the LadyMatic 425.37.34.20.57.002 is 18mm. This width is proportionate to the 34mm case and is a specific Omega construction standard for this women's line. To verify the measurement, insert a digital caliper into the gap between the attachment pins: the internal distance must measure 18mm.

Alligator leather with vegetable tanning is the noblest solution thanks to its tapered grain that does not compete visually with the diamond-set bezel. Shell cordovan offers natural rigidity ideal for the watch's weight, while Italian calf is perfect for those seeking elegance with a softer character. For everyday use, vulcanized rubber or NATO provide practicality without stylistic compromise.

The LadyMatic 425.37.34.20.57.002 features an integrated, non-removable steel lug. The strap is mounted via spring bars 18mm wide inserted into the dedicated attachment holes. To perform the replacement without damaging the case, use a dedicated spring bar remover tool and ensure that the new strap has the same attachment parameters.

Aftermarket straps must be specific for 18mm lug width with compatible spring bar attachments. We recommend alligator, high-quality calf or shell cordovan from artisanal suppliers. On milanostraps.it you will find a selection of 18mm straps customizable in sizes, finishes and colors, tailored for your specific model.

Durability depends on the material and usage. Alligator leather with vegetable tanning guarantees 3-5 years of daily use if properly maintained. Shell cordovan reaches 4-6 years thanks to the natural fibrous structure. Classic calf has an average lifespan of 2-3 years. All Casati Milano straps benefit from an 18-month warranty and can be regenerated through restoration at the atelier.
