The 7-day movement

First the question:

How much effort for the 7-day movement to automatically wind 1 day?
Now the background:

I'm no IWC 7-day movement expert. Looking at the Portugese catalog, I see there are 3 or 4 variations of the movement.

My work consists of typical desk jockey stuff. I'm an executive assistant currently so I read and send many emails everyday and basically do admin work. The most strenuous activity is pouring myself a cup of coffee.

My 5022.13 generally stays at the same power reserve on a daily basis. It maybe gains a few hours.

Should I expect the power reserve to hit max everyday or is what I describe fairly normal?

Thank you, Eric

The 7-day movement

My Port. 2000 (Ref. 5000) winds easily more than 1 day during my office job. But I have to confess that I do more than just pour me some coffee, that might add to the power res.
PS: The 5000 only needs 1960 revs of the rotor to build up the whole power res. for 7 days.

The 7-day movement

My recently purchased Port Auto 5001 was wound by the AD so I let it run down. I then gave it a small wind and set it up. I wear it only when I am not doing the dirty wet jobs of the day, then after about three hours the 5001 gets worn until the morning shower the following day, after a 2 week ownership and wearing it for between 18 to 21 hours a day it is now fully charged, the only unusual thing is that I am right handed and wear it on my right wrist

Greg, glad to see that you are now enjoying this

watch to it's fullest.

Interesting

I am left handed and normally wear my watch on my left wrist. I would think my left would have more movement. However, I may try to wear the watch on my right wrist to see if the PR increases faster.

My watch has a 18'000 Hz movement. It gains about a day while wearing it, me not being overly active. I suppose it looses less than half a day overnight, so it should gain full power reserve after a few days. As I wear a different watch almost every day, this looses significance. I wear my PPC about a day a week, I hand-wind it somewhere in the middle of its dry period to make sure it doesn't stop.

Kind regards,

Greg, glad to see that you are now enjoying this

Thanks, never in any doubt in my mind that I would, just wish I had waited for an in-house movement in the Port Chrono which I am sure will be announced soon and with a date per the Yacht Club

It depends a lot on what I do.

I have a desk job too and both my Portuguese Automatic and Big Pilot gain almost nothing when I wear them at the office. When I wear them during the weekend however, they easily gain two or even three days of power reserve per day. I don't wear them doing heavy stuff like gardening or sporting because I don't want to damage them either.

Kind regards,

Re Michael's comments. Not challenging nor disagreeing but my 5001 is now fully wound by movement without using power tools nor playing golf or tennis, just regular day to day stuff which most people do who are mobile by normal standards

I wore the watch on my right wrist today......

and the power reserve climbed a full day.

I prefer to wear it on my left wrist and I am left handed. I just feel that crown should point towards the wrist (this may be a new phobia).

Appreciate all of the comments,

Eric -- wearing the only IWC I own!

Your new phobia........

Your new phobia has a name but rather than a phobia it should be called an addiction and unlike other addictions where the sufferers are encouraged to kick their addiction by fellow sufferers, here we do just the opposite. We encourage our fellow addicts to enjoy our horological addiction with new additions and chats in this forum. I am also pleased to add that the addiction can be transmitted to freinds and family and is very very unlikely to be fatal even for real hardcore addicts

The 7-day movement

my big pilot doesn't really wind on my wrist too.
for example if i put it on at 8am and the reserve is pointing at 5days, by 8pm, the reserve will still be pointing at 5days. meaning i am wearing it just enough to wind itself. i have a deskbound job. however, if i jog with the watch, it will gain 1 day very quickly. i got a feeling the rotor is not that smooth.

I put my watch on a winder when not wearing it
