Portable, smaller watch (French Montre)
The development of pocket watches became possible only after the early 15th century, when the spring drive was invented. The shape of the pocket watch evolved from the early can watches. The pocket watches at the time of their invention were round, made of iron and about 2 cm high and 6 cm in diameter.
- 1550 emerged the so-called egg watches (oval shape)
Initially, the pocket watches are often worn concealed (in the pocket).
In the 18th century pocket watches were often trinkets that were representatively worn open at the belt (Châtelaine).
- About 1700 the watches had also minutes hands
- Since 1708 embossed cases were used
- 1726 the cylinder gear was invented
In the 19th and early 20th century the pocket watches were usually kept in the pocket. They were often equipped with alarm function, repetitions, chronographs, date indications, musical mechanisms and automats.
