Gruen watches are top quality and this one is a cut above many of their other watches. It's unusual appearance is due to two factors. The slender profile and rose-colored dial combine to give a unique Art Deco look to a easy-to-carry timepiece. It is also very thin for its era and, because of this, is classified as an "Opera Watch". This designation signified that it was easy to carry in a tuxedo vest while in attendance at the opera. It is a fifteen jewel, Caliber 381 thoroughbred movement in a yellow gold-filled case with stylized gold hands and a seconds bit at the 6 o'clock position. The case measures 39mm in diameter by 51mm from the bottom of the case to the top of the bow, by 8.5mm thick. It also sports a oblong bow and a great original dial with gold applied numerals, Circa 1939. This Gruen is very unusual and scarce and it can be yours. Fully restored and warrantied. Remember all of our timepieces come with our famous one year warranty for parts and labor so that you may buy with confidence.
