May I please ask the Pros for advice?

 As most of you know I recently restored thanks to the many giving members here my 6309-7040 but I have a small (?) problem..........
The movement I bought was supposedly (?)  a restored/serviced  movement within the last year but it only holds a charge for about 10- 15 hours regardless of how long I shake it!
Am I doing something wrong? 
Should I contact the seller who is a very well known member of the SCWF or what??

I'd suggest wearing it for a day or two, then see how long the reserve is.

You could wind the spring manually (with a screwdriver) until fully wound. Then see how long it runs from that point. Its quicker than shaking the watch, and it eliminates the auto wind function.
