It’s a poor redial, Chrono sweep is damaged and price is way low for a reason. If you were considering this watch, there are plenty of examples here to go to school on. Use the search function. Take your time and invest in a proper 30CH.
I had not see the price 3800 usd is really too high for such a watch, I would not give more than 1000 usd.
Even if you find a replacement original dial you will have a poor movement condition, certainly a poor time keeping.
