Longines Admiral Ref.8339 Cal.508 Automatic 35.0mm 1974

A sharp and versatile mid-1970s Longines that captures the brand’s knack for blending sporty practicality with understated dress watch elegance. This 1974 Longines Admiral Ref. 8339 features a well-proportioned 35.0mm stainless steel case, a silver satin dial with day-date display, and the dependable Cal. 508 automatic movement inside. With its distinctive five-star Admiral styling, slim profile, and easy everyday wearability, it is the kind of vintage watch that feels just as natural with a shirt cuff as it does dressed down.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Cal.508 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
