Master Collection L2.357.4.98.6— lug 18mm

The lug width is 18 millimetres. This dimension is measured as the distance between the two pins/attachment points that secure the strap to the case. The 18mm is a classic standard for luxury dress watches, available in a wide range of artisanal straps.

Alligator represents the most coherent choice: the natural texture of the scales dialogues perfectly with the linear geometry of the stainless steel case. Black alligator for formal contexts, cognac brown for versatility. Vegetable-tanned calf is a refined alternative, with patina evolving over years.

Use a spring bar tool: insert the flat tip into the lateral hole of the lug, gently lift the metal pin until it detaches from the case. Repeat on the other side. For the new strap, align the pins to the lug slots and press until secure. A task of seconds, requiring no special tools.

Yes, absolutely. Any strap with an 18mm lug width is compatible, including high-quality aftermarket options. Milano Straps offers a wide selection of artisanal 18mm straps in premium leather, rubber and materials specific to this case.

A quality leather strap, with vegetable tanning or alligator, lasts on average 5-8 years with daily use, longer if treated with minimal care: avoid prolonged exposure to humidity and excessive perspiration. Shell cordovan has superior durability. Milano Straps provides an 18-month guarantee on all bespoke straps.
