The watch - Passive Voice

In 1504 the watch was invented by Peter Henleinm, since that year the creations and inovations were aplicated for the watch by te factorys.

Accuracy and portability are needed in the watches, a combination made possible by the work of an engineer in Bell labs. To become a part of mainstream culture wristwatches, needed to be relatively easy to use and maintain. In the past, to wind was necessary for the watch work. But now batteries, the wearer's motion or by the self-winding mechanism are powered the watches.

Dress watches and a sports watches are had for today's consumers typically. However, wristwatches are worn by fewer people on a daily basis. Cell phone technology and automated calendar programs that alert you to the time before your next meeting are commonplace.
