Here is an interesting one currently on the swamp. We've always seen these Gubelin's and the relationship to the guilds but this one has the Gruen markings to go with it.





Cheers!

Time for me to share a box. But going for fastest post ever.
Side photo reads " 704s Rec'd Dec 30, 1933"

"Veri-Thin Pan American"; Mon, 03 October 2022 04:43

Gruens have many dial variants, so that's one reason we ID a Gruen by it's case. But what about when the watchcase looks like this?






No doubt a genuine model based off this photo from my copy of "Masterbook" (Flex bracelet dates to later period)







Did Gruen just slap on a diff dial on a Pan Am Ace case n call it good? Probably!

But the point of this post is to assign a name to my watch. This watch has an inscription with a date:1948.


First one I find with my model is August 1948. "Gruen Veri-Thin Pan American" Interesting but I too thought it must be a mistake.





Thought:1948 is a year that Gruen was the official timepiece of Pan American Airways.

Second ad is in June 48 for Father's Day sale.







Thought: While most Pan Ams are Veri-Thins, they are seldom advertised or classified this way. It usually goes in order Gruen Pan American "Ace". They keep calling Strap 570 model "Veri-Thin Pan American".

Third ad is June 1948 Father's Day again, wait is this a National ad campaign?










Normally three separate ads is enough for me to accept a Gruen Watch model name. But I'm STILL skeptical but important clue in that last ad; Esquire. Yes, Strap 570 featured in a nation wide ad campaign. What is the name of my watch?

This model is quite flat – unusual for a Curvex:














Inside there are two trademarks of William B. Ogush, Inc. (WBO in the following), the well-known WBO logo



and the lesser known “two diamonds” trademark of WBO:



I guess, the „two diamonds” brand was used to mark the case material – in this case, 14K gold.
A good abstract of WBO’s history was published in the „Cincinnati Enquirer“ of June 28, 1951:



There were two dial variants – the one shown with 12 numerals and a variation with markers and numerals (2-4-8-10-12):
