Datejust gains 22 seconds on 75 minute walk

[GARY52]

Can anything be done with my Datejust which consistently picks up 20-25 seconds when walking for over an hour. The watch picks up 4 seconds just while taking a 15 minute shower! Motion screws this watch up. It's a 1575 caliber, model 1601/34. Rolex in NYC has changed the movement twice, but it has not helped. Anything they have done has not really helped - and they have been very accommodating to me, really trying to solve the problem. They told me, this movement just isn't as "stable" as the newer movements are. I've been told by one non-Rolex watchmaker that the barrel needs to be lubricated and then the mainspring reset in the barrel. Another non-Rolex master watchmaker told me I am stuck with the problem. The hairspring guard Rolex developed to correct the motion issue and its affect on the balance won't really work with the lower 19,800 bph on my watch. HELP!!
