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

The Longines Master Collection L2.893.4.79.6 features a lug width of 21mm. This measurement represents the distance between the outer edges of the two lugs on the case. For accurate measurement, position a ruler perpendicular to the case: this standardisation facilitates sourcing compatible aftermarket straps of high quality.

For the Master Collection L2.893.4.79.6, the most suitable materials are alligator leather with vegetable tanning (for those who appreciate natural patina development), box calf in dark brown or black tones (for stable, enduring elegance), and shell cordovan for those seeking superior density and natural lustre. The sunburst blue dial pairs perfectly with cool tones (navy, black, grey) or deep browns; avoid saturated colours that compete with the dial.

Changing the strap requires removal of the lugs from the case. Use a dedicated tool (such as a ball-pin removal tool) to gently push the spring bars from one side to the other: the bars will emerge gradually. Position the watch on a soft surface to prevent scratches. After removing the previous strap, thread the bars through the new strap, aligning the passants with the lugs, then reinsert the bars until you hear a locking click. If you lack experience, consult a professional: Casati Milano offers this service with personalised guidance.

Yes, it is entirely compatible. Any strap with a lug width of 21mm will fit your timepiece correctly. milanostraps.it offers a curated selection of 21mm artisanal leather straps, customisable in dimensions, initials and stitching thread choice. Material quality and craftsmanship ensure an aesthetic result and durability consistent with the prestige of your Longines.

Durability depends on the material selected, usage intensity and climatic conditions. An alligator or shell cordovan strap with vegetable tanning can last 3–5 years of daily wear, developing a rich patina. Box calf offers comparable longevity with more stable tonality. Factors that reduce lifespan include direct, prolonged exposure to fresh water, constant humidity and salty perspiration. A quality artisanal leather strap, maintained with periodic care (gentle brushing, proper drying), can exceed 5 years, offering an aesthetic experience in continuous evolution.
