Lenzkirch Precision Regulator Clock - Mahogany case with original finish is 58" tall, 16" wide and 8" deep. The silvered dial is 10" in diameter. Original blued steel hands. The 8 day, precision regulator movement is signed Lenzkirch and numbered 1 Million and 963328 dating the clock to 1921. The movement has thick plates with adjustable jeweled pallets and jeweled pivots on the pallet and escape wheel arbors. Large knurled thumb screws hold the plates and secure the movement to the very substantial brass mount in the case. The wood pendulum rod has a 12 pound bob with a very large knurled rating nut and blued indicator pointer. The crutch slot in the pendulum is adjustable for a perfect fit on the crutch pin. The pendulum rod has a repair just above the bob. The movement is driven by a tiny 2 pound weight! A superb timekeeper.
