The same client that sent the Rolex in has now sent in his IWC. Like the Rolex, this watch also stopped abruptly after a game of golf.

Well it’s very obvious what made this watch stop! as the watch has not been serviced in a long time we also decide a full service is in order.

With the plate removed you get to the hour recorder, day/date wheels and the setting/winding mechanism.

This guy must have a serious golf swing…don’t know if it’s a good or bad one…but must be interesting to watch! 😝
Great and fantastic work as always! Mitka, I have a question. How long does a complicated movement like this take yo to disassemble, clean, and reassemble?

Hi Gary,
You never know how long it will take.
Sometimes it’s a straight forward job and it will take about 4-5 hours. Other times there are unexpected issues that add several hours of work…
Are you serious? what impact force does it take to displace that spring? I think that is the most powerful spring in the 7750 (besides the mainspring)!
Great work, btw!

If he even needs his watch repaired we know where he can send it;)
