Strap for Master Collection 42 Date Stainless Steel / Pink Gold / Silver-Diamond / Bracelet

The lug width of the Longines Master Collection L2.893.5.77.7 is 21 millimetres. This is the internal distance between the two vertical lugs where the strap attaches. It is measured with a ruler positioned perpendicularly between the lugs, from the base of one lug to the base of the other. This is a rare and almost bespoke measurement, requiring specialised straps.

For the bicolour variant in pink gold and stainless steel, an alligator strap in dark brown is the ideal formal choice. The natural pattern of the leather pairs perfectly with the gold, creating aesthetic continuity. Alternatively, a smooth black calf strap offers complete sobriety, whilst a cognac calf creates balance between elegance and chromatic warmth.

To change the strap, you must remove the spring bar pins that connect the strap to the lugs. Use a dedicated tool (spring bar tool) to push the internal spring mechanism and extract the pin. Repeat for both lugs, then insert the new pins into the replacement strap and secure them to the lugs. If you lack experience, consult a jeweller or specialist atelier such as Casati Milano.

All straps with a 21-millimetre lug width are compatible. Milano Straps offers straps specialised in this measurement, crafted in alligator, vegetable-tanned calf, shell cordovan and rubber, customisable in colour, length and deployant clasp type.

A quality artisanal leather strap lasts on average 3-5 years with daily wear, depending on the material and care. Alligator and cordovan age beautifully, developing a fascinating patina. A bespoke strap by Casati Milano is guaranteed for 18 months and can be professionally restored to extend its lifespan.
