Leather strap watches

Leather changes a watch. The same case reads dressier on calfskin than on steel, sits lighter on the wrist, and takes on the shape of the person wearing it within a few weeks. These two pieces are the collection's steel watches fitted to leather, with nothing else changed: the 316L stainless steel case, the sapphire crystal and the quartz movement are the same.

The 916 Leather pairs the 41mm starfield dial with vegetable-tanned calfskin and a deployant clasp. The 820 Leather puts the 44mm moonphase chronograph on embossed calfskin, in brown or black. Both from $39.99.
