Minute Repeater

Chimes the time on demand, to the minute.

What it does

A slide in the case activates hammers that strike tuned gongs: a low tone for each hour, a double tone for each quarter, and a high tone for each minute past the quarter. It exists because before electric light, you could not read a watch in the dark.

How to read it

Push the slide fully and count the sequence. Three low tones, two double tones and four high tones means 3:34. Never activate it while setting the time, and never interrupt the slide mid-travel.
