This is an extremely rare and collectible Longines 24 jewel, automatic diver's watch. The massive, oversized stainless steel case measures 42mm, not including the crowns. From lug to lug, it measures almost 53mm. It features a 'frogman' on the screw-on stainless steel back. This watch has 2 matching, cross-hatched stainless steel crowns. The one at 2 o'clock rotates the unusual, internal bezel ring. The other at 4 o'clock is for manual wind and time set. The high-grade, 24 jewel, automatic Longines Cal. No. 290 movement is in excellent condition and is running fine. It is marked LXW, 290, 11567967. The serial number suggests a 1960 or 1961 date of manufacture. It is extremely rare to find a vintage Longines watch movement with a 24 jewel count. Even some of their finest watches are only 17 jewels. This watch is all original except for the new Hadley-Roma leather band. The original Longines luminescent hands have lost their luminescent paint which can be re-applied by a watchmaker. The original dial has very slight foxing, typical of a watch this age but no scratches or other damage. The top of the watch shows slight wear. The plastic crystal has been polished and looks like new. The watch back has a few light scratches. The markers and numbers on the outer bezel ring have a silvery mirror like finish. The remainder of the bezel is 'jet black'. The main dial markers and numbers are white (very slight toning) with flourescent dots and dashes at the hour chapters and numbers. The red and pink spots on the photos are reflections from aur camera. This oversized watch, with black dial is full of character and would look great on your wrist! This one is a keeper! Dont' let it get away.
