So I decided to wear after 25 years again "Digital". This clock comes without annoying "status Vibrations" and yet manages to be both elegant and functional. Judging by its very clean, elegant and robust construction it also seems inexpensive.
For me indispensable are the alarm and the pleasant, approximately 2s activated, orange lighting. The metal ribbon goes well with my moderate wrist, the buckle can adjust itself and the resin housing seems to me many times more scratch-resistant and to be more resistant than the cheap housing the 168er million-selling, who loves my eight year old son dearly very easily - which is but for 18 months already well scratched.
Conclusion: I have found in the 640er the perfect reduction to a fashionably-nonsense, functional perfectly adequate "time iron". I'm curious how long it looks as good as today, on the first day!
