Strap for Master Collection 42 Chronograph Stainless Steel / Silver-Arabic / Bracelet

The lug width for the Longines Master Collection L2.759.4.78.6 is 21mm. This measurement corresponds precisely to the distance between the case lugs. A 20mm strap would be loose, whilst a 22mm strap would not fit correctly. It is essential to measure internally between the case pins to ensure perfect compatibility.

Alligator remains the most refined choice for the Master Collection: its natural grain pattern remains unchanged whilst developing a creamy patina. Vegetable-tanned calf leather offers natural ageing and character, whilst shell cordovan guarantees compactness and sheen. For daily wear, grained calf leather combines practicality and elegance without compromise.

The strap is replaced by removing the horizontal pins that secure the lug to the case, using a dedicated tool or spring-bar remover. It is advisable to entrust this operation to a professional to avoid scratches to the case or accidental loss of components. The stainless steel case is robust, but precision is essential.

Any bespoke strap made to 21mm lug width is compatible with the Master Collection L2.759.4.78.6. milanostraps.it offers a range of 21mm straps ready for dispatch in alligator, calf, shell cordovan and technical fabrics, customisable in colour, initials and stitching thread. The Casati Milano atelier also creates bespoke straps with direct consultation.

A quality leather strap, handcrafted, typically lasts 3-5 years with daily wear, depending on climatic conditions and frequency of use. Alligator and shell cordovan age by developing patina without deteriorating. milanostraps.it straps come with an 18-month warranty, and the Casati Milano atelier offers maintenance and replacement services at its appointment-based showroom in Milan.
