Hard to say on the lume without seeing it. As long as it's pleasing the the eye, it doesn't impact value.

Many LeC of that era didn't have case refs on them.

I can date the watch via the MOVEMENT serial number. It is not a 1970s watch and the dial has been redone to make it look like a Euopean model, which it isn't. This is a USA market watch, probably late 1950s.

Check the apparisal corner, there is a similar watch being discussed there. If you didn't find a ref yet on the vase back, it doesn't have one.

For USA market watches you're in the right ball park. The gold ones are usually 14k in the US though.

If it's a back set watch, and you've never done it, best to leave it to a pro. If it has a case back #, that may give us a rough idea of age. Looks like a 1960s piece.

Not sure! It *may* have a case reference number on the insides of the case back, but it looks like it is back set, so it won't be obvious to get to it.

They frequently did that re: the lume, so it's OK. It's definitely a USA market watch.

If it's really pristine and all original $1450 is OK, perhaps still a little high, any condition issues subtract vigorously from there.

Maybe $1200-1400. It's still and 18k Duoplan.

.pdf version of the book is tricky as people can just email it around to themselves.

I'm, not aware of a part like this being available from any of the parts suppliers. So yes, that's probably the best bet.

The watch has definitely been restored. I do not like the unfrosted bridge texture on a frosted movement. So I'm not sure that's how it came originally.
