”Big case” ref 6249 - advice and info?

Dear all,

Just won this piece which for sure needs som work, top right lug, crystal, missing parts in movement etc etc. Also there are some scratches on the dial (from hour hand?). I bought it based on size, 37.5mm (claimed by auction house) and case style. Normally I try to read up before I go for new references, but in this case I found very little so it was a shot from the hip.

So I am curious to know if anyone knows a source to more info? Secondly, would appreciate you Longines experts view if this is a rare reference? Should I spend to get it sorted, fix lug, maybe see if scratches can be reduced, find missing parts to the movement (AS22 I think) etc etc?
Many thanks for advice

Thanks, will do that. No, is was a fair deal imo. Normally easier to find info though...

Here´s mine. I only can find one more with original dial searching the internet.
I believe this case size is relatively uncommon.
No further info about that reference. Cal 22AS is correct.

Thanks! I have asked for extract and also if Longines knows how many of this ref was produced, lets see if there is any info available

Did you receive extract information? What did they say?
