This clock is cheap, looks good, is clearly laid out and easy to operate. With a little technical knowledge, you need the manual maximum of 5 minutes, at this point I can not connect other reviews absolutely. Even the bracelet is very elastic, wears super without any problems and is large enough for real men wrists. The clock has a variety of functions and it is a radio-controlled wristwatch, no tiresome setting and no manual switch between summer -and normal time. I can only say "Super".
