Strap for Master Collection 42 Date Stainless Steel / Silver - Roman

The lug width (distance between the spring bars) of the Longines Master Collection L2.893.4.79.2 is precisely 21 millimetres. This specification is unique to this model and excludes standard 20mm aftermarket straps. To measure your lug width correctly, verify the internal space between the metal lugs on the case where the strap connects. An incorrect measurement would result in poor fitment or excessive movement.

For the Master Collection L2.893.4.79.2, we recommend high-quality alligator (featuring regular grain and deep patina development), Italian vegetable-tanned calf leather, or sports rubber for everyday wear. Dark alligator (mahogany or black) creates elegant contrast with the stainless steel case; calf leather offers superior grip and natural ageing; rubber maintains aesthetic linearity and practical durability. Your choice should reflect intended use: formal, mixed, or intensive sports wear.

You will need a spring bar removal tool (also called a strap changer). Place your watch on a soft surface (cloth or cushion) to prevent scratches. Insert the removal tool into the small hole beneath the lug, gently press to retract the spring mechanism, and slide out the pin. Repeat on the opposite side. Align the new strap's holes with the pins, ensuring secure fitment on both sides before wearing.

Yes, with one critical requirement: the strap must feature a 21-millimetre lug width to fit correctly onto your watch's spring bars. The majority of universal straps are manufactured for 20mm lugs and will not fit properly. Always verify lug width before purchase. At milanostraps.it, you will find curated artisanal 21mm straps specifically compatible with this model.

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with moderate daily wear. Longevity depends on factors including moisture exposure, frequency of use, and maintenance (periodic cleaning, drying after perspiration). Artisanal Casati Milano straps include an 18-month warranty and can be refurbished or replaced in case of premature wear.
