This Chronograph movement is a patent from circa 1883. Patented by AH Arnold and FH Huguenin on May 3rd 1883.
A fine example of a Chronograph movement, it does require a repair or service as there is a fault at present – the setting of the time does not work. When the keyless winding push piece is pressed in and the crown turned, it does not change the time, it sounds as if the gears are not quite marrying up.
The movement features in a watch discussed on page 315 of Alan Shenton’s book “Pocket Watches, 19th & 20th Century” as well as a picture of the patent.
The movement is signed WB Lake, Romford – a retailer of watches, barometers and instruments.
The watch winds and ticks happily without issues. The minute indicating wheel is functioning correctly, jumping once per minute. The hour hand is not original and has been replaced at some point, although finding a blue steeled hour hand shouldn’t be difficult. The minute hand also has the blued effect worn away.
The movement measures 41.93mm on the reverse, 45.22mm on the dial and is 10.5mm in thickness.
