Very chic 18 kt gold Onsa Superautomatic with a 30 jewel automatic movement. The 12.6 g gold case has a nice and large diameter of 35 mm and it is in very neat condition. The elegantly shaped lugs, combined with the gold and the gorgeous dial, make it a very chic item. The dial with overlaid hour indices is very elegant! The dial features a minute scale on the inside of the hour indices. The dial is marked: 'Onsa Super-automatic 30 Rubis' and beneath that 'Incabloc Ferrotex Antimagnetic'. All the way at the bottom the dial is marked Swiss. The screwed caseback, which is also made of 18 kt gold, is marked with the number 1138. Around this it is marked 'Waterproof Incabloc Antimagnetic Automatic'. The inside of the caseback is marked with the gold hallmark 18K/0.750. The watch features a 30-jewel 1560 movement it keeps time neatly. Time adjustment also works smoothly. The rotor is marked 30 Rubies Swiss HM 1560 Patented Onsa Automatic. The 1560 number can also be found on the movement. All in all it is a very chic watch which is both technically and optically in very neat condition. Highly recommended.
