Strap for Master Collection Date 29 Diamond

The lug width is 15 millimetres. This measurement represents the distance between the lug holes on the case and determines compatibility with aftermarket straps. It is essential to measure this accurately before ordering a replacement strap, ensuring that the lugs fit snugly into the watch's spring bar slots without forcing.

For this 29mm dress watch, the most appropriate straps are vegetable-tanned alligator (cognac or black), shell cordovan, or tanned calf leather in warm tones. These choices enhance the formal character of the timepiece. For more informal contexts, a navy blue NATO strap or a perforated rubber strap in grey represents a practical and aesthetically coherent alternative aligned with the watch's minimalist DNA.

The strap is replaced using spring bars: small spring-loaded pins connecting the lugs to the case. To change the strap, use a dedicated spring bar tool to gently compress the spring, extract the pin, and remove the old strap. The new strap is installed by reversing this procedure. If you are inexperienced, the operation can be performed at Casati Milano.

Yes, any 15mm lug width strap is compatible with the L2.257.0.87.6, provided the spring bars are in optimal condition. However, from an aesthetic standpoint, it is advisable to select straps that respect the dress watch's formal style: high-quality materials and sober colours ensure visual coherence with the case and the 29mm proportions.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) has an average lifespan of 4 to 6 years with daily use and ordinary maintenance. Longevity depends on exposure to moisture, temperature variations, and intensity of use. Casati Milano provides an 18-month warranty on bespoke straps; afterwards, the leather develops a natural patina that enhances the aesthetic value of the watch.
