The Ascot, Patent 20. June 1887, Swiss Made. Measures 53 mm wide, x 65 mm tall, x 19 mm thick. It weighs 103 grams. I left it on its original patina, no buffing or polishing. Back covers snap good and tight. The dial is porcelain, it has hairlines. Missing the chronograph hand & the two register small hands. All pinions are present. Can’t test chronograph. The glass beveled crystal is in good condition. The manual wind Swiss made movement sets OK (side button). Nice “snail type” regulator. It winds but mainspring is broken (slips). Service history is unknown. PLEASE CHECK MY PHOTOS CAREFULLY. We work very hard to describe our items at the best of our knowledge, ask any questions if you are not sure.
