Big Pilot winding mechanism

Hi, I have a BP 5002 but I'm not sure if the winding mechanism works correctly. I wear it every day (not during the night) but still have to wind it every 10 days or so. Is this a normal issue with this caliber or should I have a doctor to look at it?

This is not normal. If you wear it every day, or even every other day you should not have to wind it.
My 5004 will wind at least a couple of days of power reserve for every day I wear it.

Thanks for such a quick reply - I'll see a doctor Monday!
