AT-38 series are 5ATM water-resistant and ATC-40 series are 10ATM water-resistant.
They can be used under conditions in the rain or sweat, but if the pressure of the water hitting the device is much higher than the static pressure such as taking the shower, or water from the faucet, the water resistant function may not be working

ATC-40 series may lose or gain time (-15seconds~+25seconds) slightly throughout the day (Temperature between 5℃~35℃)
They are automatic winded watches (can also be hand winded), and the time accuracy of mechanical watches mainly depend on the amount that the mainspring is wound. The power to keeping is provided by the natural motion of the wearer's arm. It is strongly recommended that you wear more than 8 hours a day to make sure the watch get enough energy to run
Poor time accuracy and shortage of running time of mechanical watches may be caused by less natural motion of the wearer's arms or keep unworn more than 30 hours for example, little amount of movement of arms during office work. At this time, you can self-wind about 30times
*it is recommended that you wind up the mainspring every day, at a fixed time
