Mechanical designer watches for women which are used nowadays were invented in the Middle Ages. During that time, human beings had evolved enough to invent advanced mechanical systems to measure time. Mechanical designer watches for women were born, however according to Baresford Hutchinson, both the identity of the inventor and their origin are still unknown. Some historians claim that these watches already existed in the late Middle Ages, i.e. in the last decades of the 13th century. Some European cities had public clocks in the early 14th century. One of the clearest examples of this fact is the astronomic clock of the City-Hall in Prague dated in 1486 created by Nicolas de Kadan and Juan Sindel. This clock has a sphere-shaped calendar palced at the button of the watch. There are also more examples of these clocks, for instance in Milan, Italy there is a clock in the San Eustorgio tower dated from the 1309. In the Cathedral of Toledo, Spain there is a record found in the second half of the 13th century in which a “disrupted horologe”appeared that was supposed to be one of the clocks Alfonso X (the wise) mentioned in 1267.
s for men are characterized by including a quartz piece inside their mechanism. This quartz element is used to perform the necessary pulses at regular intervals to measure time. Quartz uses to be cut as a sheet and introduced inside a cylinder which is used to protect this material. The quartz crystal hast to vibrate inside designer watches for men mechanisms. Therefore, it must be powered by an oscillating magnetic field generated by an electronic circuit. This is the main difference among other designer watches for men (clepsydras, hourglasses, etc..) where pulses are physically or mechanically generated. 
s for men are based on physical movements, and are totally different from balance-wheel watches. They are formed by a synchronous motor and some gears. The main characteristic of electric designer
