Rolex Explorer II Winding Question

[Task59]

I have just purchased a 5 year old Rolex Explorer II in nice condition which has just had a service at a Rolex approved watchmaker.

I've read many posts on the topic of manual winding frequency as mine basically stops after roughly 3 days of 24 hour wearing and after winding 40 full turns at the start of day 1. I have also tested the watch after winding 40 full turns and not wearing and it operates for just under 48 hours before stopping, so looking at other posts this looks normal.

I'm an active person meaning I walk a couple of miles most days with my dog, and my job is desk/car based. I jog and swim about 4 times a week for 30 minutes each session, and this is the only time the watch isn't worn. I do wear the watch whilst in bed.

My bottom line question is, is there something wrong with the watch as I feel that it stopping and requiring winding every 3 days seems too frequent ?
