Our greatest score in a long while! Beautiful gems, perfect for your office or study. Genuine, bona-fide surplus 1960’s German Navy radio-room, bulkhead mounted 8-day ship’s clocks. Made by two famous German clockmakers, Bürk and Junghans, made with a nickel-plated brass housing, with watertight, hinged bezel with a screw-bolt lock. Has a 7-jewels, 8-day movement, with hour, minute, and sweep second hands. You key-wind it on the face, where there’s also the slow-fast adjustment. (You should mount and let the clock run for at least a week before adjusting the speed). Both clocks have the two three-minute radio-silence markings in red, and the Junghans also has the green listening markings, per the International standards for the use of 500 kHz, which first appeared in the second Berlin International Radio-telegraphic Convention, which was signed November 3, 1906 and became effective July 1, 1908. The second Service Regulation affixed to this Convention designated 500 kHz as one of the standard frequencies to be employed by shore stations. All of these clocks were thoroughly checked out by our German clockmaker, and run beautifully. All have some discoloration and scratches on the dial and case, due to their long service life in the Navy. The clocks measure overall about 8.6” Ø back x 3.5” deep x 7” Ø front and weigh about 3 lbs 11.5 oz. All come with a key, of course. Take your pick.
