A watch that rarely comes out of my vault. My 115 year old Keystone Howard model 5. 19-jewels, motor barrel, the triangle in a circle in an arrow signifies highly adjusted. This one has run continually now for 17-days, and is within one minute. 24-hour double-sunk enamel Montgomery dial, Canadian case. I鈥檝e enjoyed running it. (I have 3 of these.)
