HIRSCH HHirsch George Embossed Calf Leather Watch Strap - 20mm, 22mm, 24mm - Black, Blue, Brown, Golden Brown - Quick Release Performance Watch Band

Excellent quality, stylish and very comfortable even in hot weather. I have one on a Seiko SARB017 and one on a 38mm Hamilton Chronograph. Will be buying another (the Robby) for my Sinn 556a.
