Frequently asked questions
What is the correct lug width for the Omega LadyMatic 425.60.34.20.55.001?
The lug width of the LadyMatic 425.60.34.20.55.001 is 19 millimetres. This dimension represents the internal width between the spring bars that connect the strap to the case. To verify it, remove the original strap and measure with a calliper: it should measure exactly 19mm. On milanostraps.it you will find an exclusive selection of compatible straps in this size.
What is the best strap material for the Omega LadyMatic in rose gold?
Alligator represents the absolute choice of excellence for the LadyMatic 425.60.34.20.55.001. The natural structure of the scales creates parallel reflections that harmonise beautifully with the soft geometry of the case, and vegetable tanning develops a unique patina over time. Smooth calf constitutes the ideal contemporary alternative when seeking austere simplicity, with fine grain that enhances the chromatic contrast between rose gold and dark leather. Shell cordovan offers structural rigidity and exceptional patina for summer occasions.
How do you change the strap on the Omega LadyMatic?
Strap changing is accomplished via the spring bars located inside the case, at the shoulders of the lugs. Obtain an appropriate tool (spring bar tool or pin remover) and position it on the lug shoulder: by exerting gentle pressure, the spring bar compresses and allows you to remove the strap. To install the new strap, insert the spring bars into their seats and press until they click into place. If you are not familiar with this operation, ateliers such as Casati Milano offer strap change services with personalised consultation.
Which aftermarket straps are compatible with reference 425.60.34.20.55.001?
All straps with 19mm lug width equipped with spring bars are compatible. On milanostraps.it you will find straps in alligator, calf, shell cordovan, natural rubber and NATO fabric, specially selected to guarantee quality and longevity. Each strap can be personalised in size, initials and thread colour according to your aesthetic preferences.
How long does a leather strap last on the Omega LadyMatic?
The lifespan of a leather strap depends on the material, frequency of use and environmental conditions. High-quality vegetable-tanned alligator can last 5–8 years with regular maintenance (light cleaning, annual conditioning with specific creams). Good-quality calf typically lasts 3–5 years. Shell cordovan, being more robust, can reach 8–10 years. Casati Milano guarantees 18 months on its artisanal straps and offers restoration services when the leather begins to show signs of natural wear.
