I bought these watches from the Watchesbytimepiece company through Amazon - it was my first purchase and experience with Amazon - and full satisfaction. Excellent price, fast (international) delivery (well before the deadline), nice packaging. And watches exceeded my expectations. I was afraid that they would be too big (not comfortable to wear) and too complicated (too many functions). But they are quite flat and due to special extensions on the bottom they fit nicely to wrist. Their functions can be very intuitively controlled. The manual seems really huge/impressive/scaring - but soon I found that many functions I was able to control by just trying without need to read it in manual. Functions seem to work well - tried already altimeter in Alps, compass in laboratory using magnetic fields, thermometer ... . Full satisfaction.
