Beautiful 10k gf gruen - Gem。Stunning, authentic mid-century ladies cocktail wristwatch from the legendary Gruen Watch Co. This watch is manual wound and fully operational. I have wound and tested for accuracy myself. Dating from the 1950s, this exquisite timepiece features a highly sought-after elongated \"marquise\" or \"navette\" (almond-shaped) case profile.
