Strap for Classima Executives

The lug width of the Classima 8786 is 18mm. This measurement is taken between the two spring bars (lugs) on the case where the strap attaches. It is crucial to verify this measurement before ordering a strap to ensure perfect compatibility with your timepiece.

For the Classima 8786, we recommend high-quality alligator, which emphasises the timeless elegance of the watch. Alternatively, vegetable-tanned calf offers excellent softness and durability, whilst shell cordovan is ideal for daily wear with superior moisture resistance. Your choice depends on your lifestyle and intended use.

Strap replacement requires a specialised tool called a spring bar tool. Position the watch with the lugs facing upward, insert the tool into the small slot beneath the case to compress the spring bar, then slide the old strap outward. Insert the new strap in reverse orientation and release the pressure. If you are inexperienced, we recommend having the operation performed by a qualified watchmaker.

Yes, provided the strap is specifically designed for an 18mm lug width and the dimensions are compatible with the case's width and thickness. Always verify that the deployante (folding clasp) or closure system is proportionate to the watch's mass. All our artisanal straps from Milano Straps are tested for compatibility with this reference.

A quality leather strap (alligator, calf, cordovan) typically lasts 3–5 years with daily wear, provided adequate maintenance is observed: avoid prolonged water exposure, protect from direct sunlight, and clean regularly with a soft cloth. The natural ageing of leather is a virtue, not a defect—it develops patina and character over time. Custom straps from Casati Milano include an 18-month warranty against manufacturing defects.
