Produced during the 1970s, the Wittnauer Professional Chronograph ref. 7004A embodies the bold and highly functional design language that came to define many sporting chronographs of the era. Closely associated with motorsport and professional timing aesthetics, the model combined robust chronograph functionality with distinctive visual details that helped separate it from more conventional chronographs of the period. Powered by the dependable Valjoux 7733 manual-wind movement, the ref. 7004A is particularly recognized today for its unusual burgundy bezel and oversized lollipop chronograph seconds hand, both of which contribute to its unmistakably 1970s character. Combining strong wrist presence with vibrant design cues, the Professional Chronograph has become an increasingly appreciated vintage chronograph among collectors seeking something distinctive beyond the mainstream offerings of the era.

The unusual colored bezel, wide lumed hands, and lollipop second-hand make this Wittnauer stand out. While not the rarest of references, to find one with such an attractive bezel and original bracelet is not easy.
