Longines Admiral 10K Gold-Filled Ref.69-394 Cal.343 1966

A sharp, classic vintage Longines Admiral in 10K yellow gold filled, paired with a unique silver sidesweep sunburst dial that catches the light beautifully. Powering the watch is Longines’ automatic Caliber 343, a unique off-centre rotor movement from the golden era of Swiss watchmaking. Not to mention this case came special under the Longines-Wittnauer partnership under Ross, which was a US based company who would make the cases for Longines before assembling the Swiss made movements in their New York based factory to be sold in the US. An interesting practice done by other brands like Omega as well to get around customs and save them costs.

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.343 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
