Comments about the data

Remarks
strange: Placing minute wheel and pinion under the balance allows a relatively big balance.
Most movement registers are too old to contain this movement line. Only Boley and Flume mention single variants, unfortunately without complete data. As Boley specifies the same staffs and stems for Longines and Record, both are listed here respectively.
These movements were likely designed by Record around 1970, and also applied by Longines. Below only variants known from lists or real watches are listed.
