Strap for Day-Date 36 Everose Gold - Fluted / Silver - Baguette

The lug width of the Day-Date 36 (128235-0087) is 20 millimetres. This width is standard across the entire Day-Date 36 collection and corresponds to the distance between the two case lugs. Respecting this measurement is essential for ergonomic fit and to avoid stress on the lug attachments.

For a Day-Date 36 128235-0087 in 18k rose gold, we recommend vegetable-tanned alligator in aged cognac, which creates tonal harmony with the metal. Alternatively, shell cordovan with vegetable tanning offers lustre and structural rigidity, whilst vegetable-tanned calf provides a patina that evolves over time. A rose gold deployante buckle completes the aesthetic solution.

Strap replacement requires a specialised tool (spring bar tool) to compress the fixing pins that connect the strap to the case lugs. Work on a soft surface (microfibre cloth) to avoid scratches. For maximum precision, it is advisable to consult a certified watchmaker or specialised craftsmen such as Casati Milano.

Yes, any strap with a 20-millimetre lug width is mechanically compatible. However, construction quality, structural rigidity and finishing vary significantly between manufacturers. To ensure durability and aesthetic coherence with a watch of this category, we recommend craftsmen specialising in high-quality vegetable leather.

The lifespan of a leather strap depends on the tanning method, daily use and environmental conditions. A high-quality alligator or cordovan strap, subjected to vegetable tanning, typically lasts 3–5 years with regular use. Proper maintenance (cleaning, protection from water and humidity) significantly extends longevity. Casati Milano provides an 18-month warranty on manufacturing defects.
