Badalassi Wax - Waxed Leather Strap - Milano Straps
Definition
Badalassi Wax is our benchmark leather for the most demanding watch straps. It comes from Badalassi Carlo, the historic San Miniato tannery specializing in vegetable tanning. It's a robust bovine leather treated with natural wax, making it water-resistant while developing a rich, almost oily patina. When you work it, you feel the fiber's density: perfect for a strap that must withstand the wrist of someone who knows the difference. The wax ages beautifully, creating character with time. It's not the classic polished leather of sport watches; it's the choice of those wanting a strap that tells the story of its use. On a vintage Rolex Datejust 36mm or an IWC Pilot's Watch, Badalassi Wax returns that tactile sensation missing in industrial straps. It requires conscious maintenance—occasional natural cream application—but you repay the leather's trust in this way.
Frequently asked questions
Why choose Badalassi Wax for a watch strap?
Because Badalassi Carlo has been tanning for four generations using vegetable methods. The result is leather that breathes, changes color with you, neither dries out nor cracks. On an Omega Seamaster or Patek Philippe Calatrava, this leather doesn't compete with metal: it enhances your wrist with controlled softness. The natural wax protects it subtly—it's not synthetic fur—preserving the naturalness you sought when choosing leather over steel.
Is it suitable for straps in 18-22mm sizes?
Completely. In fact, Badalassi Wax shines precisely in classic sizes: 18mm for vintage dress watches, 20mm for IWC Pilot's Watch, 22mm for Rolex Submariner. The fiber's density makes it ideal for these thicknesses. It doesn't bend unnaturally, supporting the watch's weight without giving. For a 20mm strap, I recommend wearing it for the first two-three days: the wax softens slightly and the leather conforms to your wrist permanently.
How to maintain a Badalassi Wax strap?
It's not complicated. Avoid prolonged salt water and aggressive detergents. If wet, dry it naturally—never with direct heat. Once a month, apply natural fat cream (like French saddle cream) to the entire surface, massaging gently. The wax will regenerate, the patina will deepen. If the strap loses some softness after months of use, it means the wax has settled: perfect, it means it's aging well. It's the price of vegetable tanning quality—and every penny is worth it.
