Footnote
The Montreal model, introduced in 1972, was available with white (W), blue/white (B), blue (BC) and black (N) dials with contrasting subsidiary dials. Fitted with the popular Cal.12 automatic movement with substantial, classic 1970s case, the model was part of Jack Heuer's expansion into the North American market.
