I have this Debert compressor style for about a month, it keeps time well, it has no operating problems,I have only noticed for a few days that it has a charge that does not exceed 12 hours, at the beginning I had not noticed it, and therefore, I wore the watch for 24 hours, even at night,so I took it off my wrist and, after about 12 hours, I found it stopped... it mounts a Miyota 82 series ... why does this happen? ..are we sure that these movements are genuine Japanese and not Chinese clones?...for the rest it works very well

If you were able to identify the movement as a Miyota 82 series, and particularly if it was signed 'Miyota, Japan' then you can be sure that it is a Japanese movement. Being a 'clone' would not explain a 12 hour power-reserve anyway, as that is way too short for any automatic movement.

This is the caseback of my Debert....

That is without any doubt a Japanese movement, no better or worse than its nearest Chinese equivalents. And its power-reserve should be about 30 to 36 hours straight off the wrist, or 42 hours if fully hand-wound.

ok, so it is established that it is a Japanese movement, I will wear the watch as long as possible, so as to let it reach the maximum charge, and then I will check ..
