An omega watch is a precision mechanical instrument, and like anything mechanical that you expect to last a long time it needs maintenance. It has seals that wear out, and mechanisms that need lubrication. If you drove your car every day all day, how long before it needs a service? I don't expect casio owners to understand, the same as a yugo driver would not understand you spending £150 on a Continental tyre when he can get a nankang for £20 that will do the same job. Your casio/lorus/whatever will look **** and be in the bin while my Omega will look as good and perform as well in 25 years time as it does now. Simple as that.
