Strap for Master Collection Date 25.5 Stainless Steel / MOP / Bracelet

The lug width of the L2.128.4.87.6 is 13mm. This measurement represents the structural connection between the case and the strap, measured from the internal point of the upper lug to the internal point of the lower lug. It is essential to respect this metric to avoid mechanical play or tensions that would damage both the case and the strap.

For this feminine dress watch, we recommend straps in alligator with vegetable tanning for aged patina, or satinized calfskin that requires minimal maintenance. Shades of dark brown, burgundy, and black create elegant pairings. The leather must be soft to the touch but robust in stitching, as the reduced case size requires precise proportions to maintain visual harmony.

Gently remove the existing strap by inserting a small flat tool (spring bar tool) underneath the lug where the tension spring is positioned. Press inward to release pressure, then extract the metal pin. Repeat for the other side. Insert the new strap by aligning the holes and repositioning the metal pins until they click into place. If unsure, consult a professional.

Yes, provided the aftermarket strap strictly adheres to the 13mm lug width. Non-conforming straps pose risks of case damage and instability during wear. Always verify with a digital calliper before purchase. Our bespoke straps guarantee complete compatibility and watchmaking-level finishing.

Durability depends on material and usage. Vegetable-tanned leather of quality lasts 3-5 years with regular maintenance (gentle cleaning, protection from excessive moisture). Satinized calfskin has a similar lifespan. Alligator tends to last longer (5-8 years) thanks to scale structure. The thin 13mm lug does not impose excessive stress on the strap, extending longevity compared to heavier models.
