___________________________
Comments: The Calvin is a member of the "first generation" to utilize Hamilton's rectangular 980 17-jewel movement. It was also part of the "curved to fit the wrist" series.
The "curve to fit the wrist" series utilized a two piece case construction with a moisture proof pendant and crown feature. Gold-filled models included in this series were the Cabot, Boone, Carson, Nelson and Bartley.
Of the early wristwatches that contained a 980 movement, the Calvin is one of the scarcer models and was available for only one year - 1935.
The Calvin was produced in yellow gold-filled only.
