Very nice looking Dynamic!
I'm having my Dynamic serviced by Swisstime right now - it costs around £425.
I sent it in in December and should be getting it back any day now.
The service cost more than the watch (around £300), which wasn't keeping good time, but it should come back as good as new....
I'll report back once I have it.
If it's not too nosy, how much approx was the IWC?
Again a lovely looking watch.... you can't see the dink in the photo.
