This Westfield Driver's watch was designed to wear on the edge of your wrist so that could see the time easily with your hands on the wheel of your car. That way you don't have to remove your hands from the wheel when you are steering the car! The watch has a gold filled case with a stainless steel back that measures 27mm wide and 31mm from lug to lug. The Swiss movement has 7 jewels, and our watchmakers have it winding, setting, and keeping time like the day it arrived here from Switzerland, circa 1939. If you want an unusual watch for your wrist or collection this may be it. Remember all of our timepieces come with a one year warranty so that you may buy with confidence.
