Other: This rare Gruen Precision "Dato" is absolutely gorgeous in the metal. The silver sunburst dial glistens when it catches the light and especially out in the sun. We love the symmetry of the date window placement at 6 o'clock, a subtle design element that is seldom found on vintage watches. Powered by a nice Swiss manual-winding movement, this particular example is in superb original condition and presents incredible value at this affordable price point.
