What Watches are made of
If you fancy a gold watch but want something more usable than a solid gold watch you can opt for a gold plated one. These have the same lustrous colour as gold but come at a fraction of the price. New technology in this field means that instead of layering the gold on top of the base metal it is now infused into it (by a process known as Physical Vapour Deposition or P.V.D.).A number of different materials are used to construct watches. Gold WatchesGold is a material not often used for watches. There are two main reasons for this; firstly that gold is an expensive material, secondly that it is the softest of all the metals. Gold watches are dress watches, normally purchased for special occasions and are not suitable for everyday wear. One advantage to having a gold watch is that gold has an intrinsic value. If the watch can no longer be worn the gold still has a value according to its weight.
