Strap for Day-Date 36 Everose Gold - Diamond / Blue-Green - Baguette / President - Diamond

The lug width of the Day-Date 36 reference 128345RBR-0084 is 20 millimetres. This measurement represents the distance between the two lugs of the case and determines compatibility with straps. Any strap with a different lug width will not be compatible with this model.

For a Day-Date 36 in rose gold (128345RBR-0084), alligator remains the most coherent choice both aesthetically and technically: the ordered scales do not conflict with the precious metal of the case, and dark brown or cognac tones create a natural chromatic harmony. Vegetable-tanned calf leather is ideal if you seek a patina that evolves over time. Woven NATO straps are recommended for summer wear and minimalist pairings.

Strap replacement on the Day-Date 36 requires specific tools: a spring bar removal tool, a stable work surface, and good lighting. You must carefully remove the spring that holds the strap within the lug, insert the new strap, and reseat the spring. We recommend consulting a qualified watchmaker if you lack experience, as the risk of damaging the case is concrete.

Yes, an aftermarket strap measuring 20mm is entirely compatible. Lug width is the critical parameter: you must ensure the strap is certified for 20mm width. Platforms such as milanostraps.it offer bespoke straps in alligator, calf leather, and noble materials constructed specifically for this lug width.

The lifespan of a leather strap varies based on material quality, usage patterns, and climate. A high-quality alligator or vegetable-tanned calf strap typically lasts between 3 and 7 years with moderate daily wear. Humidity, perspiration, and sun exposure accelerate ageing. Rotating between 2–3 straps periodically extends the lifespan of each individual piece significantly.
