What an amazing time piece !!!! It would have taken hours & hours to create. Firstly it works and was tested over a 20 hour period, kept reasonable time and was still ticking very strongly. Secondly its a key wind, lever set pocket watch with winder at 3 and a seconds dial at 6. Thirdly all the details have been cut away from the plate, no makers name, jewels etc. From the USA so possibly Elgin, Waltham etc. Its a very large movement approx 46mm in diameter, the glass & metal case is 55.6mm in diameter. Just superb !!!
