The history of the brand is very interesting and for a detailed look I recommend reading this thoroughly researched on-line book by Paul Schlisser. Schlisser breaks down the story of Gruen from the arrival of Dietrich Gruen in America to the closing of their Ohio plant, Time Hill, in 1958.In the time that Gruen was around, they were a truly an innovative watch brand.Nevertheless, a 17-jewel manual wound movement with date function that still runs very well powers the watch.When I said this watch was mint, I really meant it.At 3 there is a fairly large date window (compared to the overall dial size) and at 9 is a slightly different marker, with a Dauphine shape.Running along the outer edge is a printed black index for the minutes and seconds, with cool little domed lume dots at 12, 3, 6 and 9.As far as affordable vintage goes, these are an interesting option for people who are looking for something simply to wear.This watch is likely not worth much, though an exact price is hard to establish.
Since the watch is from the 70’s, well after the Gruen’s were a part of the brand, I am not sure if that is still the case.
Given its condition, around 0 would be max value, though a lesser price would be likely.
So, if you happen to be looking for something to scratch that vintage itch that wont break the bank, add Gruen to your searches.
Their history is very rich, albeit obscure, and this article only barely scrapes the surface.
Though they produced their movements in Switzerland, they were a major US brand for a long time, one that produced some pretty excellent watches.
I happen to be lucky enough to have been given a nearly mint example from 1974, which has a distinctly mid-century design that is quite beautiful.
