Longines Conquest Ref.7290-633 L.633.5 35.0mm 1990s

A sharp, neo-vintage Longines Conquest Heritage Ref. 7290-633 from the 1990s, featuring a factory finished silver sunburst dial paired with elegant gold dauphine hands and crisp gold shark tooth indices. At 35mm, it wears perfectly as a refined everyday dress watch. Making a clean, understated, and unmistakably Longines timepiece.

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.L633.5 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
