First run 7 jewel J. Watson watches have a unique engraving with the name "London" on the barrel bridge and had an English appearance (at least some did). With this designation they might have been made for export; on the other hand, more likely, they were another Robbins experiment and made to look like an English import. The second run all appear to be engraved "Boston"; some with 11 jewels. The plain porcelain unsunk dial on this exhibited watch has English appearance. The silver HC serial # 320 with no makers name has an engine turned inner lid.
