The founder of Sinn has passed away at the age of 102. SJX has an excellent write up about his extraordinary career that I highly recommend reading.

He leaves behind a legacy of excellent watches.
One interesting fact that I was not aware of was his acquisition of assets from Breitling when it was insolvent, which explains why Sinn still sells watches that look almost identical to the Navitimer.
