By the Jaeger Watch Co. Inc. U.S.A. Manufacturer's Model 43A-4. Stores reference 6A/2197. American designed clock with an 8-day keyless seven jewel lever movement. Metal case approximately 6 x 5cm with 5cm black dial having luminous Arabic numerals, hands and sweep second hand. Single winding and setting knob at the 6 o'clock position. The dial is in excellent condition and marked '8 DAYS' & 'MK.4'. The case is also very good bar a few paint chips. Manufacturer's plate riveted to the rear with Air Ministry marks, order, part and specification numbers. With 1942 date code. Looks good but the mechanism is a bit erratic. It ticks away for upto a day or so then stops, possibly due to a weak mainspring? The hour hand also requires minor adjustment as it is slightly out of line - quite a simple job. Recently repurchased from a client. Stock code C23112.
