My experience with Ivan, the proprietor of European Watch and Clock in Guelph has been completely positive. He repaired and cleaned my 100-year-old French pendulum wall clock and two years later it's running fine and quite accurately. My 80-year-old German Westminster chime mantle clock, which he recently cleaned, is, after my pendulum adjustment, accurate to 2 seconds in 24 hours; that's more accurate than some digital devices. As a collector I can tell you that some clocks simply cannot be repaired or repaired perfectly. That said, Ivan has been entirely honest and fair with me and my experience tells me does really good work.
