豪雅，獨特及大碼，不銹鋼自動上弦腕錶，配計時功能及日曆顯示，“Montreal”，型號110503B，約1974年製

The Montreal model was launched in 1972, during a period when Heuer began to significantly expand its range of watches. Certainly one of the firm's most colourful models ever made and standing out by its distinctive oversized case, the Montreal enjoys much popularity by aficionados of 1970s timepieces.
