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

The lug width of the LadyMatic 425.65.34.20.51.001 is 14mm, which is the distance between the case attachment pins. This specific measurement was calibrated by Omega for the proportions of the 34mm case, a characteristic of Lady models. All straps you purchase from Milano Straps are verified for this exact measurement.

For a LadyMatic in 18-karat rose gold, we recommend alligator leather in brun foncé or bordeaux tones, which enhances the warmth of the case without competing visually. A premium alternative is bordeaux shell cordovan, which develops a unique patina over time. For daily wear, cognac-coloured Tuscan calf offers softness and versatility. If exposed to humid climates, the Tropic rubber strap is the practical choice without aesthetic compromises.

Changing the strap on a 34mm LadyMatic with a thin case requires care. Use a dedicated spring bar tool to remove the pins, pushing them downward to release the internal spring. Work on a soft surface (cloth) to avoid scratches. If you lack experience, entrust the operation to a watchmaker: the Casati Milano atelier offers this service with WhatsApp updates and warranty.

Yes, provided the strap conforms to the 14mm lug width measurement. On Milano Straps, all straps from the 14mm collection are tested and compatible with the LadyMatic. Always verify the technical sheet before purchase: it must clearly indicate 14mm lug width with fastening tolerance within ±0.2mm.

A superior quality alligator or calf strap, with daily wear and regular maintenance, lasts 4-6 years before showing visible signs of wear. Shell cordovan can exceed 8 years. Durability depends on sun exposure, humidity, frequency of wear, and cleaning. Casati Milano offers an 18-month warranty on custom straps and recommends monthly cleaning with a damp cloth and annual treatment with natural grease for calf leather.
