Will be interesting to see how many responses you get re: JLC on the Omega forum. I'm not familiar with the JLC font, but the first (top) watch looks like the "SWISS" at the bottom is an odd font. Could be the appearance through the curvature of the crystal? Hope others will chime in. They may not be Omegas, but they'll certainly serve as good examples of how to determine dial originality. I know I can benefit from that ongoing education!
Real. One "tell" is the continuous integration of the swoop under the name into the first and last character. (Welcome to the Vintage Omega sub-forum where everyone is friendly and helpful
IMO, these are both original. I really like the first - love those sword hands, but the second with the applied breuget numerals & notched lugs is also quite nice. I won't claim expert status, but I do own a few early JLC and have looked at a ton of them. There is a dedicated forum (hosted by Zaf Basha) at http://www.jaegerlecoultreforum.com/ if you want to have them vetted there too.
