Frequently asked questions

What is the lug width of the Omega LadyMatic 425.60.34.20.63.001?

The lug width of the Ladymatic 425.60.34.20.63.001 is 12mm. This measurement represents the distance between the inner edges of the case lugs and is essential for selecting the correct strap. Always verify with a ruler positioned perpendicularly on the lug to avoid errors.

Which strap material pairs best with the Ladymatic in rose gold?

Genuine alligator is the natural pairing: the structured grain and natural brown color create aesthetic cohesion with rose gold without visual conflicts. High-quality alternatives include vegetable-tanned leather (which develops patina over time) and shell cordovan (elastic and durable horse leather). For more casual styles, NATO straps or vulcanized rubber also work well, transforming the watch's character.

How do you change the strap on the Omega LadyMatic?

The strap is changed using a spring bar tool: insert the flat tip into the slot beneath the lug, press upward to compress the internal spring, then extract the metal pin from one side. Repeat on the other side, then insert the new strap by aligning the buckle holes with the pins and letting the springs expand. Be careful not to bend the pins excessively to avoid damage.

Which aftermarket straps are compatible with the 425.60.34.20.63.001?

All straps with a 12mm lug width are compatible with the Ladymatic 425.60.34.20.63.001. On milanostraps.it you will find a selection of 12mm artisanal straps in various materials (alligator, calf, shell cordovan) and finishes. We recommend verifying that the deployant buckle does not exceed the maximum thickness to preserve the watch's aesthetics.

How long does a leather strap last on the Omega LadyMatic?

Durability depends on material and usage: a high-quality alligator or shell cordovan strap, with moderate use, lasts 3-5 years before needing replacement. Vegetable-tanned leather tends to develop patina and can last longer if subjected to regular maintenance (gentle cleaning and occasional conditioning). Moisture and contact with perspiration accelerate wear; preventive maintenance significantly extends useful life.
