Had as operations Ruhr a similar, even by Casio and was totally satisfied. Very reliable and durable even to shock. After many years of closure bracelet was now but become so facilitated consistently, so I then lost somehow. Thus, needed a new one. The only thing I's criticisms at the new clock that the pins for the settings protrude too far. In certain hand movements to adjust the 12/24 hour display. On the positive side, the metal bracelet, you better tolerate in warm weather as leather or even plastic. Overall, it is a clock with good price-performance ratio.
