7 Day movement timekeeping poll

[cxbxax]

my 5001 42jewel is also between 7-15 sec fast.

My 5001 is running +11 seconds a day. I gave it to my AD two months ago, who sent it to Richemont down in Texas I believe, who then had it sent to Switzerland (I believe there was also an issue with the power reserve). I expect to have it back within the month, I'm more settled now to hear that many owners have encountered similar issues.

My 5004 is just under 7 seconds fast every 24 hours. I have pretty much gotten past the inaccuracy issue as I love this watch. Just nice to know it seems to be a somewhat common attribute of the 7 day movement.

Good poll OP...

good info shared here, as i hope to get the 7-day Port as my first IWC in the future

My BP is still under warranty and running +15sec/day, quite annoying. I intend to bring it back to IWC to tune it for better accuracy. My friend's 5001 is running very fast too. I am not sure whether it's common problem with 7 days movement.

Your friend also very unlucky. Buy an IWC watch with 7 days in-house movement but performance worse than the ETA 7750.

Just got my 5001 back from Switzerland yesterday after an 11 week wait while it was being serviced for being +11 seconds and having issues with the power reserve.. Had her on my wrist for around 7 hours yesterday, woke up today to find the time is dead-on to the second from when I set the watch

I'll continue to monitor for the week and hope for the best!

Been keeping a log of my watch for the past 5 days since getting my 7-day back from service. I wear my watch an average of 8-12 hrs per day. Here is what I have found:

• 14-Dec, 9:45am set watch, 6.75 days charge
• 15-Dec, 8:00am, -2 sec, 6.50 days charge
• 16-Dec, 11:00am, -7 sec, 6.50 days charge
• 17-Dec, 9:00am, -10 sec, 6.50 days charge
• 18-Dec, 12:00pm, -13 sec, 6.25 days charge

Overall the watch has lost 13 seconds in 4 days, averaging -3.25 seconds per day. I'll wait a few weeks for the watch to settle and see the results. However, IWC's website does say that their watches should never run slow.. still much better than the previous +11 seconds per day

I've had my BP for 5+ years. Returned to IWC twice within the first 6 months for gaining +15 secs per day. Posted my annoyance on IWC website got my fingers burnt by mod - maybe I told the truth?
The spring link broke whilst I was wearing it, repaired and serviced. Perfect timekeeping for 1 year now gaining approx 30 sec per day. Lost interest in it now wearing some of my other watches. Great thread.

interesting, I didn't know that the IWC 7 day movements were so plagued by inaccuracies.

The 5004 has always been one of those "must have's" in my book, but now I'm reconsidering.

I agree with the previous post. I have grown to very much like this watch, which had been on my very short list of watches that I may actually buy some day.

However, there's no way I would spend this much money on a watch which likely will keep such poor time.
