Screw down case back with a good Gasket. 30m WR
This is supposed to use a Miyota movement.
It has both Analogue and LED, independent "movements".
Now, the analogue movement is at the font and the LED module is stuck on its back, making the overall watch thick.
The Analogue movement runs on a tiny AG4 battery, whereas the LED, digital module, runs on a thick CR2032.
Thus, the analogue part stopped running, whereas the Digital part still has a full battery. (The digital does have a lot of functions, like alarm, stopwatch, date, so if you use these you will need the bigger battery)
You remove the larger battery to get to the smaller one.
3 conducting springs, connecting the movement with the case, so be careful.
I could not see the analogue movement as it is hidden by the digital module. Overall the analogue movement was more accurate, but they were both decent enough.
Construction is pretty good, a quality product overall
