In the course of the 17th century the centre of watch production in Europe shifted from town to town for some special reasons.

This however does not mean that all watches produced at that time had a minute hand and were round in shape. There is a wonderful watch by Parisian master Auguste Bretaunneau: it is of square shape, with one hand and a crystal lid instead of a face glass which was already usual for the second half of the 17th century.
