Today I am wearing a classic icon that was an essential piece for Allied forces in World War II: the Hamilton Khaki Field Bronze Black Dial H69459530.
This watch is powered by the Hamilton CAlibre H-50 hand wind movement based upon ETA 2801-2 with 17 jewels, biting at 21,600 VPH, and has a whopping 80 hour power reserve.
I have been fortunate and my model gives me an average of +3.82 seconds per day.
