Nice watch! I've had great results from Juerg Boo at Artomatique in Irvine. I can't remember his watch makers name (maybe Alex) but he disassembled my silver/orange Autavia and ultrasonically cleaned each part during the service. He even updated me along the way with photos of the watch completely taken apart. He even replaced the crystal that had a chip in it at no extra charge and sourced some hard to find parts for the winding mechanism. I highly recommend him.
