The Conquest was the Longines waterproof watch, and those seals have kept this in great shape.  Model reference 9045.


From the serial number on the movement we can accurately date this watch to being made in 1966.  The sales paperwork, with the same serial number on (but the model reference is slightly wrong) dates the watch to being sold in 1969.  Either year could be considered valid for a birth year watch.


Any Conquest would not have been a cheap watch, and a solid 18k gold one would have been an expensive, considered purchase.  Back in the 1960’s Longines was an independent company and competed with Omega and the like – many would consider the Longines the better watch back then.  Now the brands are under the same umbrella and Longines is marketed at a mainly lower price point than Omega, but This Conquest can more than hold its own against the equivalent Seamaster.  The case is very solid, and this would need a lot of gold.  The screw down case back also requires much more gold than a clip on type.  There is an enamel disc on the rear of the case back, which has worn at the edge as you would expect.  The dial is very good, and the acrylic crystal has a magnifier ‘cyclops’ built under the glass to help read the date.  The automatic, 24 jewel calibre 291 movement is running nicely too.  The leather strap is new and branded Longines, as is the gold plated buckle.
