The clock is ticking pretty accurate with less than 5 seconds forward, and I was very pleased with the screw-down crown, the second hand stop and the possibility for manual winding. Even the date on precision. From the feel of her, I do not want to complain too. The silicone band feels for silicone, and the housing for stainless steel housing. The luminous material is also applied cleanly, and it gives light in the dark. Only the unidirectional rotating bezel could rest a little cleaner, but all in all, I think, the clock offers a lot for your money!
It would be presumptuous to compare the clock with a clock, which cost a five or ten or twenty times. But I contend in the price category "Mechanical Diver about a hundred euros" one is served here quite good, although one for "only" twice the price even a Seiko 5 gets.
