Designed with a hardy 46mm stainless steel case, easy to read face and luminous hands, this Grenson watch is based on the original Pilots model of the 1940's. It's powered by a traditional automatic 24 jewel mechanical movement, which is visible through the case back and fastened by a sleek Italian leather strap in tan. The case is water resistant to 100m/330ft, and the scratch-resistant sapphire crystal lens secures against everyday wear. Total Strap Length: 24.5cm, Width: 2cm
