These driver's style watches are sought after by vintage watch collectors, especially the very long ones like this. Measures 53mm end to end! All original 1940s Gruen Curvex type Gruen Veri-Thin with a dial that has been tropicalized over the years. With a 21 jewel Gruen Veri-Thin caliber 335 movement inside the 10K Yellow Gold-Filled Gruen signed case. Original SWITZERLAND signed dial has faded and taken on a nice patina. Just fantastic aging. Model 335-558. Watch is offered here for restoration/repair. Balance staff is good. The watch ticks but is starting and stopping, so the movement needs servicing. Watch has its original recessed gold unsigned crown. Strap lugs width is 15.5mm. Case is 24mm across (not counting the crown). Has its original curved glass crystal that has some nicks/scratches. 

When reviewing the many photos, which serve as a large part of the description here, keep in mind they are all magnified 2.5X to 5X to show all characteristics of this watch clearly. But macro pictures exaggerate elements that are more acceptable in person in normal viewing. The case is excellent just light scratches; what you see are reflections, not flaws. Watch is sold As Is and As Described as not running with No Returns. Timekeeping not guaranteed. Watch has not been serviced and service history is unknown.
