Yes, that is a variant for that watch.

The original crown on that model is either not signed or a cursive "LeC" for the USA market.

Sorry, I don't have any signed crowns left. They'll show up on eBay on occasion.

The "Club" line was the budget line of JLC in the 1970s. They often do not have JLC made movements, so in my opinion they're not in thet much demand.

Sorry it's a modern watch, I have no information.

It's a case reference E855, with movement caliber K825. I would need the serial number of the movement, though these are typically 1965-1968.

It won't have much value beyond the scrap value of the gold.

I'm not seeing a ton of value in the watch beyond the gold value (if it's gold). Probably an early 1960s watch.

I'm not sure I understand the question. What do you mean by "original" configuration?

The Fab. Suisse dials are usually for watches sold in France.

To me the bottom example you show has the wrong hour and minute hands.

No, this topic is covered extensively in my book. The LeC case back is correct even for a JLC dial and movement.
