I am looking for some opinions on this 30CH. Thanks in advance!

 

Stunning!

 

Compare—
Dial. Counters. Ink.

 

I think it is a different dial config, a different ref.

Was looking for a table of Longines hands posted here some time ago. It’s a handsome watch.

 

Is this the one you're looking for, Larry?

 

Looks from chart like the hands are legit. Beauty. Thanks @Warthog ...

 

I'm of the opinion that it deserves to be on my wrist... if not yours!

GLW!

 

Looks quite nice.
Longines will verify for free by email based on case back and movement serials. It’s worth doing.

 

Perhaps one of the finest 30CH models designed. The design of the case is more unique for the period and has a distinct Art Streamline Moderne Industrial Design look to it.

 

what do you think of this one that you posted. Incorrect crown? Hands and dial look good? Just trying to learn more on these.

Thanks

 

Definitely incorrect crown.

 

I think good dial good hands. Not a Longines crown. Matt Bain is a good seller, so doubt any serious problem with the watch except asking price is huge.
