Long time lurker, first time poster.
Just won an auction on the 'bay for a watch from a company called Sherco.
The face is signed Sherco with either "Thelomatique" or "Shelomatique" (script makes it hard to determine) above the 6. Just from style, I'd guess it's a 60s/70s piece.
The movement is a 17 jewel Bidynator that appears to be signed Wakmann Watch Co.
A Google search for Sherco pulls up Associated Diamond Brokers in Philly, which used Sherco as a name. So maybe it's a former in house brand name with import movement. But thinking there's someone here who might know more history on the piece.
