·What is the meaning of the letters GCT on some Longines dials?
“GCT” printing on dial?

·That question popped up again on instagram just a few days ago. My understanding is that nobody worked it out yet. Here’s one I saw for sale last year. Sorry for the crappy picture.
Incidentally, how do we know it’s GCT ?
Has that been confirmed somewhere, or is it just a best guess ?
I mean it could be TCG, or any sequence...

·I did ask a friend and his reply was:
We found it in the Longines archives, few company sold at the end of ‘30s in Italy watches with G.C.T. on the dials, but I did not find any connection to a company or military order, it is still a mistery!

·That’s great I learnt something.. or at least relearnt something that I’d forgotten 🤦
So they all went to Italy and it’s confirmed as GCT. Given that there are so many hardcore Longines fans in Italy I assume this must be a very hard puzzle to solve.

··ΩF InvestiGatorThis may help with the definition of GCT:

Not sure of the connection between the Longines and “GCT”. Could that just be the logo of the jeweler who originally sold the watch?

·Here’s an explanation as to the why...
http://www.mwrforum.net/forums/showthread.php?45036-Hamilton-GCT-24-hr-AN-57401
Quote (isologue).
The Hamilton AN5740 was a master navigational (GCT) watch. GCT stands for Greenwich Civil Time, a term adopted by US astronomers after the measurement of Greenwich Mean Time was switched from a noon start to a midnight start. (On a 24-hour watch dial I suppose this is important!)
But pretty sure this GCT has nothing to do with the GCT monogram on the wristwatch dials. Jewelers monogram sounds quite plausible, especially as it appears on a wide variety of models.

·I've been told that GCT = Greenwich Civil Time.

·We've had discussions about this with Jennifer Bochud - a UK collector has one and was wondering about it too.
Jennifer is suggesting that anyone who has one in hand or sees one send in the pictures with movement serial numbers and perhaps a pattern can emerge. I too would vote for a jeweler in Italy, but I think a number of people have gone nowhere trying to find which it might be.

··GrasshopperWas there any conclusion to this? Just picked up one of these Longines featuring the logo as well from my trip to Japan. Will post up some pictures when I get back!

··GrasshopperFrom the archives:
"It is fitted with a Longines manually wound mechanical movement, caliber 12.68Z, and was invoiced on 16 December 1937 to the company Ostersetzer, which was at that time our agent for Italy."
Also includes was a link to this article with the same archives picture. No definitive answer on who this possible retailer was though!

·Just adding this Movado chrono example that turned up on my IG - clearly this phenomenon is not Longines exclusive, and has our fellow Zenith collectors equally baffled.
