Strap for Master Collection Date 25.5 Stainless Steel - Pink Gold / Grey / Bracelet

The lug width of the L2.128.5.07.7 is 13mm. This specific measurement has been calibrated to suit the proportions of the 25.50mm case and ensures optimal visual balance between the watch body and the strap. Measurement is performed by positioning a millimetre ruler on the inner shoulder of the lug, from outer edge to the opposite edge.

Alligator leather remains the reference material for the Longines Master Collection L2.128.5.07.7. The natural fine grain texture does not compete with the lustre of the rose gold bezel; rather, it enhances it through subtraction. Vegetable-tanned calf leather is an excellent choice for those seeking a patina that improves over time, developing a mellified texture with age.

Strap replacement is carried out by removing the spring bars present in the lugs. It is recommended to use a dedicated tool (spring bar tool) to gently extract the bars without damaging the case or lugs. Once extracted, the strap slides off easily. The new 13mm strap is inserted by following the reverse path, ensuring that the spring bars engage correctly in their seats.

A high-quality natural leather strap, when worn daily, maintains its aesthetic and structural characteristics for 4-6 years. Durability depends on wearing frequency, climatic conditions (humidity, sun exposure) and the type of tannage. Vegetable-tanned leather tends to last longer than industrial tannages because the fibre remains more robust over time. Quality ateliers such as Casati Milano provide an 18-month guarantee on their products.
