I was winding my Buren yesterday and I suspect the mainspring has let go. Can anyone suggest a watchmaker in the UK or Europe that might be able to fix and service for me. I will be in London Monday of next week and then Zurich the days after.

This is is the watch in question.

 

You could try sending a PM to stefan

He is your man for complications.

 

Excellent. Thank you.

Cheers
