At that price, it could be a reasonable buy, but I'd try to get it cheaper. I have seen that sort of fuzzy writing on excessively patinated watches before, and the lume seems to have aged appropriately. There's a loose piece of it below the 4 o'clock marker, however The date wheel seems oddly untouched. Very nice case and the crown seems correct.
It does not appear to be a redial, but the lacquer/clear coat/technical term has become discolored or 'patinated.' If it doesn't bother you, then I think 300 would be a decent price if the movement is in good shape. More pictures would give a better idea one way or the other. I am not certain about the crown. Be careful, this might have radium lume. I don't see any T's next to Swiss made and it looks like a 50s model. But I could be wrong.
The movement looks like it is in very good condition. This is an auction with buy it now price. The bidding start in almost the same price $280-290 . Case back looks like it has lots of marks?
Serialnumber is in the 1800000 so around 1961-62. So radium is unlikely as it's was banned 1950 something?
