The Graham Silverstone Time Zone watch has all so called complications housed in a thin 42 mm case: Automatic movement, hours, minutes, central second, and date. This minimalistic yet practical  wristwatch in stainless steel even sports a GMT function.

The numerals on the dial are typical GRAHAM. A big 6 and a big 12 popped out. These numerals help when it comes to reading time, and they are too typically GRAHAM not to have them. Pure GRAHAM DNA. Just like the refinement of colored stitches on the bracelet.

The Silverstone Time Zone comes in three dial versions: Black Carbon, Silver and Gulf Blue.
