Strap for LadyMatic Co-Axial 34 Red Gold / Diamond / Brown / Bracelet

The lug width of the Omega LadyMatic 425.65.34.20.63.002 is 20mm. This width is the standard for all LadyMatic models of this generation and is decisive in strap selection: an undersized or oversized lug width compromises the aesthetics of the case-to-strap transition and can cause mechanical stress on the spring bars over time.

For the 425.65.34.20.63.002 model in red gold, alligator leather in cognac or aged tobacco tones represents the most refined classic pairing, with a pronounced grain that complements the case. Alternatively, vegetable-tanned calf leather in black or dark brown offers a contemporary and versatile aesthetic, developing a natural patina that harmonizes with the gold's reflections over time.

The Omega LadyMatic 425.65.34.20.63.002 features bayonet attachments. To change the strap: (1) position the watch with the lug facing downward; (2) gently slide the old strap upward to disengage the retention hooks; (3) insert the new strap by aligning the lug with the attachments and push downward until it clicks into place. If you are unsure, your trusted watchmaker can complete the operation in a few minutes at minimal or no cost.

Yes, provided they comply with the certified 20mm lug width. Milano Straps offers online a selection of 20mm straps specifically tested for mechanical compatibility, available in alligator, calf, rubber and shell cordovan, with custom personalization options at the Casati Milano atelier.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 5-8 years of daily use, depending on care and exposure to moisture, sunlight and heat. Vegetable-tanned leather develops a patina as it ages, increasing aesthetic appeal. Rubber straps last 7-10 years while maintaining mechanical properties unchanged, although without the visual evolution of leather.
