The watch is in working condition and has not been used much. I assume that the back cover has not been opened and repaired or maintained.I bought the watch about 20 years ago. I didn't use it. It is in very clean condition and can be considered a collector's item. It is understood that the mainspring is loose. In this way, there is never a possibility of breaking the mainspring (a thought). I think the back cover of the watch has not been opened. The original thin tissue paper was still there. I took a picture and put it back. The machine is also in untouched condition.The watch works for about 8-10 hours in its current state. If the buyer says he wants to buy it after the mainspring has been serviced, we can send it back after the mainspring has been replaced. I haven't done anything to the watch, it looks just like I bought it. As a history of FAVOR Watches: What is the history of favor pocket watches? Favor was a brand of the German watch and movement manufacturer Schätzle & Tschudin. Founded in 1909, the company was based in Lörrach, directly on the Swiss border, until 1911. In 1911, the company moved to nearby Weil am Rhein, where the first movements were produced from 1913. NOTE: I do not accept to sell via Escrow Account. The pocket watch cannot be sent before the watch's fee reaches my own account.
