Rare MINERVA SWISS military chronograph

In 1902, Minerva became a ‘manufactory’ for watches, designing and manufacturing the most important watch parts, such as the movement, in its own design workshops. The earliest Minerva wristwatch was produced in 1909, but Minerva's greatest success came in 1923 with the launch of Calibre No. 20, a chronograph with a column wheel mechanism, a Breguet balance and 17 jewels. With the launch of this watch, the company earned its reputation as a manufacturer of complicated movements of exceptional quality.
