Day-Date 36 118208-0095— lug 20mm

The lug width of the Day-Date 36 is exactly 20 millimetres. This measurement refers to the distance between the two lugs (the mounting points where the strap attaches to the case). Accurate measurement is critical to avoid incompatibility: position a ruler perpendicular between the two lateral lugs and you will obtain the 20mm that characterises this model.

For a Day-Date 36 reference 118208-0095 in 18-carat yellow gold, dark brown alligator or superior quality calf leather represent the optimal choices. Alligator offers a geometric texture that ages magnificently whilst maintaining absolute formal elegance. Vegetable-tanned calf provides natural softness and a patina that develops over time. Avoid cold colours such as blues and greys: yellow gold accommodates warm palettes—cognac, caramel, burgundy, black.

Changing the strap requires a specialist spring bar removal tool. Position the watch on a stable, soft surface. Insert the tool's tip into the small gap between the lug and the case, applying gentle pressure to retract the spring. Once retracted, the spring bar (the metal pin) slides out from the case lugs. Remove the old strap and insert the new one, ensuring the spring bar is fully locked on both sides.

Yes, any strap with a 20mm lug width is mechanically compatible with the Day-Date 36 118208-0095, regardless of brand or origin. However, to guarantee maximum quality and longevity, we recommend straps crafted from premium materials (alligator, calf, shell cordovan) and finishes that respect the standards of a watch of this calibre. Technical compatibility does not exclude aesthetic and construction preferences.

A premium-quality leather strap, subject to regular maintenance, has an average lifespan of 3–5 years with daily wear. Factors such as climate, humidity, frequency of wear and leather quality directly influence this estimate. Alligator tends to last longer than standard calf. Vegetable tanning ages with visible character, whilst chrome tanning maintains a more uniform appearance over time. Rotate amongst multiple straps to extend the life of each.
