Our Leather Apple Watch Bands are made from Italian Calf Leather — a leather which is beautiful aesthetically, but also durable for day to day wear. Finishes, such as Space Grey, Space Black & Gold Aluminium, are created using anodised 316 Stainless Steel - a metal that does not rust, tarnish, or turn your skin green. We plate our hardware at 0.8 microns for maximum durability & a perfect colour match.
