Frequently asked questions

What is the lug width of the Longines Master Collection L2.793.5.79.7?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Longines Master Collection L2.793.5.79.7 is 21mm. This dimension is specific to this model and determines compatibility with aftermarket straps. The 21mm width is measured between the case lugs and represents the available space for strap insertion.

What is the best strap for the Longines Master Collection L2.793.5.79.7?

For the Longines Master Collection L2.793.5.79.7 with rose gold and steel case, we recommend <a href="/pages/termine-glossario/alligatore">alligator</a> straps in medium brown or cognac, which dialogue naturally with rose gold and enhance its warm tones. Alternatively, smooth calf leather in black or burgundy maintains balance between luxury and versatility. For a more casual approach, a grey steel or greige silk NATO strap offers sophisticated contrast.

How do you change the strap on the Longines Master Collection L2.793.5.79.7?

The Longines Master Collection L2.793.5.79.7 uses a standard spring bar system. To replace the strap, remove the bars with a dedicated tool or visit a watchmaker, extract the previous strap and insert the new one. The bars must click securely into the 21mm lugs. We recommend having the operation performed by specialist personnel to avoid case damage, or consulting the Casati Milano atelier for bespoke guidance.

What is the lifespan of a leather strap on the Longines Master Collection L2.793.5.79.7?

A quality leather strap, with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, develops natural patina over time and maintains structural integrity for 3 to 5 years with daily use and ordinary maintenance. <a href="/pages/termine-glossario/alligatore">Alligator</a> tends to last longer due to skin density.
