The run between mechanic and electronic watch design

For many centuries clocks and watches were typically mechanic devices. Mechanically stored energy was transmitted to accurately paced movements, and ultimately indicated by pointers on a face by means of a series of interlocking gears and pedulums.

The electronic technology entered into the design of some few watches and clocks a long time ago when the mechanical energy source began to be replaced by batteries and electric motors.

Then in the 1970es the fully digital watches were introduced to the maked, even though the invention was much older. The reason for bringing this kind of watch on the market exactly at that time, was that by now the digital curcuit technology was so far developed that all logical functions and monitor function could be made into the size of a watch, and that it was even possible to build even more function into a watch with digital technology than with the contemporary mechanic technology. The digital technology could also be made more accurate.

The digital watches were introduced to the market mainly by japanese manufacturers, and they nearly managed to compete the European and especially Swiss menchanical watch manufacturers out of market.

However, the manufactorers of mechanical watches were not willing to give up, and they began an ambitious research program to develop the mechanical technology to give the same accuracy as the digital one. After some years, they could bring watches out on the market with the following adventages: Great accuracy, optimum robustness, independence of bateries that must be replaced or recharged and with traditional indicator faces that in many ways is more practical than digitally indicated figures.

For some years the following situation have existed: If you wanted a watch with great realiability, robustness, longevity, independence of batteries and accuracy, the you should buy a mechanic watch. If you wanted a watch with a lot of logical functions, a digital watch is the answar.

However, the digital technology has also evolved. For example is it by now possible to integrate solar panels into a digital watch, and a digital watch can by now have integrated a radio resceiver that resceives exact timing information from external sources. The digital technology has also become very cheap. However, digital technology is still far less robust than high quality mechanic technology, and is outdated very fast.

Also mechanic technology is evolving. Microelectronics has long been available. Now also micromechanics is an existing concept, and even molecular mechanics is being developed. Soon many logical functions that by now only can be achieved through microelectronics can be integreted into a mechanic clockwork.

The future of high quality watches will probably be a combination of mechanics and electronics. The watch will have a major mechanic part that performs the basic timing logic and monitor function, and that can work independently of any electronics.

The mechanics part of the watch will be of an material and artistic quality that is not possible to achieve by electronic components.

They will have a electronic part that can resceive timing and other information through a radio resceiver, perform all types of advanced logical functions and adjust the mechanical part with exact timing information. This digical unit can easily be replaces and updated when becessary. If the electronic part brake, then the mechanic part still wil work, and if the mechanic part breaks, the electronic part will also still be working.

Already now you find units with external design as a watch that also have cellphone capabilities, and the development in the future will integrate steadily more communication, measurement and computing capabilities in watchformated units togeather with the timing capabilities.

The future high end watches will probably also integrate all kind of physical measurements and physical allarms, for example measurement of temperature, humidity, barometric pressure, radioactivity, content of gasses in the air, earth magetism, compass direction and probably many more things.

Future high end watches are also likely to intergrate measurements of vital parameters of the person that wears it, like pulse, temperature, skin resistance, blood oxygen, blood carbon dioxid content. They will also likely have intergrated the possibility of sending wireless allarms based on these measurements or on environmental measurements to centrals of many kind for people wanting to have those possibilities. They will further likely have possibilities of wiroless tracking of persons for those wanting these possibilities.

All the described functions of future watches are allready or will be functions also of the cell-phone. One may wander what will be the trade-off between the watches and the cell-phones. Probably all functions that one have to look at with a quick glance, for example during sport activities will be integrated in the watch.

Functions that need greater and more advanced user interfaces will be the natural realm of the cellphone. However, there will be situations where it is practical to also have cellphone capabilities in the watch, and basic cellphone functionality will also probably be integreted in some advanced watches.

The problem with integrating everything possible in the watch is not communication, measurement, computation or dataste. The problem is the user interface, since many advanced functions need a big and complicated user interface.
