Scarce Gruen "Pentagon" men’s Art Deco design presentation wristwatch in solid 14K yellow gold with blue enamel, circa 1933.

The Gruen “Pentagon” has a 5-sided case and was a design exclusive to Gruen. First appearing in the early 1920s, the model was quite popular, but sales tapered off by the 1930s. Solid gold examples are quite scarce and this is the first one I have offered in almost 20 years. This example was a special presentation for Sun Life of Canada. It is in excellent condition showing only light wear. Caseback is excellent, with the presentation engraving filled with hard blue enamel, which is showing some minor loss in a few spots. Refinished dial is superb, has gold embossed numerals. Has new glass crystal. This watch is powered by its correct 19-jewel Gruen Veri-Thin manual wind movement, just serviced and running strong.

Price $550.
