Notice: I am not an horologist so my description is based on my experience and observation. I have described this timepiece to the best of my knowledge. This description, coupled with the photographs, should accurately reflect this item’s condition. And, while this timepiece is listed as working, the same was observed during a minimum of a 72-hour test period. Most timepieces are observed for more than a week before I list them in working condition. This test, however, is no guarantee the unit will continue working far into the future. As always, with a timepiece of this age, a professional service/cleaning is recommended to ensure perpetual operation. If you have any questions, or need clarification of any stated term, please send me a message. Thank you.
