Classicwatch Vintage Watches

Hi,
May I seek your advice on this Vintage JLC?

What is its Reference No. and Movement Cal. No?

Is:
1) it Authentic?
2) its dial untouched?
3) a 18K vintage JLC 1960?

Thanks so much!

Hard to tell from the quality of the photographs. You will need a shot of the insides of the case back and movement. It's probably a caliber 449 in there.
