Hello,
Since a week I own a Portugieser Automatic (5007-03) that I bought on the pre-owned market. This is my first IWC watch and is actually a timepiece that I have been thinking about / following for about a decade. Thus far, the accuracy of the watch turns out to be great (about +5" per day).
As indicated in the title of the post, my question relates to the winding performance. I have worn the watch for about 5 days now (8-12h per day) and I have noticed that during the day the automatic winding system more or less (actually slightly less) compensates for the power that is lost during the night (when it is not on my wrist). Since I am wearing the watch, the power reserve fluctuates between 5.5 and 6 days. I must add that I am working in an (home-)office environment though.
Is this the winding performance that can be expected from the newer 5007 models please? And does the winding performance decrease as the power reserve increases (so slower build-up as the maximum power reserve is attained)? The watch was first sold to the original owner in early 2018, so I feel it is a bit early to hand it over for service... unless you would advise otherwise.
Any thoughts or experiences on this matter are much appreciated!
Best regards,
Tim
