Fair price JLC P478?

Im not up on vintage JLC but anytime a seller says it’s been serviced but can’t provide proof I think it’s highly likely to mean one of the following;
1. It hasn’t been serviced at all, but they’re gambling that if they sell all of their watches with that description, only 1 in 10 will come back with issues at which point they’ll carry out a cheap repair as that’s more profitable in the long run.
2. It’s had a quick and dirty service by a watchmaker who just churns them out quickly and cheaply.

There’s always the possibility it’s had a good service by a competent watchmaker who just doesn’t provide paperwork to their trade customers but that’s less likely than there other two options.

I'm not an expert like @gatorcpa and @Tony C., but your watch looks legit to me. There's really no way to tell if it has been serviced, but it looks superficially clean, so it certainly might have been serviced.

Or the seller could have taken the movement and dunked it in lighter fluid. That would make it look clean. The only way to know for sure is to have your own watchmaker inspect it.

Because the radium was taken off and new lume was painted on. So it is no longer original like yours.

I think the Swiss is OK. Just distorted by the crystal.
