Strap for Constellation Manhattan 28 Quartz Stainless Steel / Yellow Gold / MOP

The lug width measures exactly 18 millimetres. This dimension is standard for Constellation ladies' models of this generation and must be verified with precision using a ruler, measuring the distance between the inner edges of the lug seats. 16mm or 20mm straps are not compatible and would cause excessive play or constriction of the case.

Alligator represents the noblest choice, with its distinctive rectangular grain that pairs perfectly with the mother-of-pearl dial. Vegetable-tanned calf offers versatility and develops characteristic patina with natural aging. Shell cordovan, though rarer and more costly, ensures natural lustre and extraordinary longevity, making it ideal for a timepiece of this calibre.

The strap is replaced using a dedicated tool (spring bar tool) to remove the spring bars from the case back. Insert the tool's tip into the small lateral slot of the lug, press gently to release the spring, then extract the lug from the hole. Repeat on the other side. To install the new strap, reverse the procedure, ensuring the lugs are fully engaged and the strap is symmetrical with respect to the case.

All straps with a lug width of 18 millimetres are compatible. The complete collection of 18mm straps in alligator, calf, shell cordovan and other materials is available on milanostraps.it, customizable for length, colour and finishes. It is important to exclude any 16mm or 20mm strap, which would not fit the watch's lug seats.

A high-quality artisanal leather strap, if subjected to moderate daily use, lasts on average 3–5 years. Determining factors are leather quality (alligator, shell cordovan and vegetable-tanned calf last longer than common leathers), exposure to weather, humidity and frequency of wear. Regular maintenance (cleaning with a soft cloth, annual conditioning with natural wax) significantly extends longevity. Casati Milano straps include an 18-month warranty and are repairable or replaceable.
