Power reserve problem

[rexon]

Corum A7750 28.000 is in question here. I got it about month ago.

Watch worked just fine for some time and now it can not gain almost any power reserve from wearing. I'm usually wearing it for 10 hours/day. Once it's taken off, it would work for about 4-5 max and then stop.

When manually winded (~30 turns) it works for about 35h.

When on winder it's working just fine for days.

However, it seems that almost no power reserve can be gained by daily use.

Is there anything I can do about this?

Another thing, most A7750 (28.000) I have will not fully change the date (date wheel as usually stuck between two dates) from time to time. As I pull the stem our in most cases date will move to correct position.

Sounds like your movements are all in need of general servicing (cleaning/lubing). Try Ziggy or a local watchmaker who works on reps & chronographs.
