I think the dial and hands are original with the hands having been re-lumed and the dial markers not. These hands are typical of the period and were used on some references along side dauphine hands. The case back engraving on these models was feint and would have probably looked like the picture below. I don't like the attempted brushing of the back but if I was buying the OP's watch and the price was right it wouldn't stop me.
As usual it all comes down to price, these are 33.5mm hand winding non-chronometer watches with a snap back so not exactly highly sought after but would make a nice addition for somebody looking for an affordable piece.
