Thanks to the merger of several firms, C-T-R’s product line included a wide range of timeclocks and scales in addition to tabulating machines. Watson gradually shifted the focus to tabulating – and later, computers – but some of the other product lines lasted a long time. IBM’s Time Equipment Division was sold to the Simplex Time Recorder Company in 1958, almost 50 years after the merger.
