Vacheron Constantin
Malte 30630/S22G-9899— lug 19mm

The lug width of the Vacheron Constantin Malte 30630/S22G-9899 is 19 mm. This width is determined by the tonneau geometry of the case and is not interchangeable with the more common 20 mm without creating aesthetic misalignment between the strap and lugs.

For this white gold reference with tourbillon, the most suitable strap is polished Mississippiensis alligator with regular grain, in midnight blue, mahogany, or black. Mirrored box-calf leather is a more understated alternative. Both options respect the aesthetic and technical level of the timepiece.

The strap is replaced by removing the spring bars that secure the strap to the lugs using a dedicated forked screwdriver or lever tool. It is recommended to entrust this to a watchmaker or specialized atelier to avoid scratches on the white gold case. Casati Milano offers this service by appointment.

Yes. Aftermarket 19 mm straps with tapering to 16 or 17 mm at the buckle end are compatible, provided they respect the curve of the Malte lugs. Milano Straps offers a selection of 19 mm straps in various materials and finishes, handcrafted and adaptable to this reference.

A quality leather strap — alligator or box-calf — has an average lifespan of 2–4 years with regular use, varying based on exposure to sweat, moisture, and UV rays. Proper maintenance with specialized nourishing cream for exotic leather and rotating between multiple straps significantly extends the life of the strap. Casati Milano offers an 18-month warranty against manufacturing defects.
