A good product for those looking for a vibrating alarm clock to wake up discreetly in the middle of the night. Alarm function by vibration quite successful but not always effective if not the wrist while sleeping with earplugs. I slipped into the pillowcase on the side of the pillow and is nickel. Ergonomics unchanged since the 80 of my adolescence! Look simple but nice (very readable LCD backlight + button). Only small inscriptions painted around the dial operation are small and difficult to read without glasses. Watch massive enough that I do not wear every day but I plan to use for sports activities (waterproof and solid).
