As I understand it...
GUB didn't make it easy for future generations: there are three different versions of your caliber 70.1, all stamped 70.1 on the plate, as shown on yours.
The basic version had a ring balance and incabloc shock protection on the balance jewel.
The step up, "Guteuhr", had a 16-screw balance and an inhouse, proprietary shock protection system (see yours, which looks like a rectangle).
The highest, "Guteuhr Chronometer" had the same construction as the one above but was timed and adjusted to chronometer specs.
This was documented on a certificate that was issued with the watch.
Thus, your watch is consistent with the highest quality 70.1 version, as it has the screw balance and GUB shock protection, and is labeled
Chronometer on the dial. The icing on the cake would be the original chronometer certificate, which should carry both the case number and the
movement serial number on it. A long shot, but maybe one of the modern Glasshütte companies still has the old GUB chronometer records. Could be
worth a email...
Enjoy your beautiful pieces,
Tom
my three vintage GUB Glashutte watches
we have a long weekend here. feeling a bit tired after going out for last two days. today was just resting at home and took this opportunity to take out some of my watches from the boxes to clean them up and also polish them. just realized that i have thr...
Spezimatic
Additional info to your GUB75 calibers. Spezimatic (short form of Spezialautomatic) is the round shaped automatic caliber from GUB. It had two version: GUB75 with date indication (that's is in your watch) and GUB74 is without date (that's in my restorated...
thanks, Ger...
thanks, Ger. i did not know Spezimatic to be form of Spezialautomatic. interestingly to learn new thing. looking from your Spezimatic, it looks more handsome without date! stefan
Great trio of Vintage Glashutte, Stefan.
Especially the Grand Mother of the 60ies, and the Chronometer. Any chanvce to have some movement pics? Best, Nicolas
here you go...
hi Nico, managed to find these two movement pics from my hard drive, but both of them were taken by the sellers. the quality looks not too bad. from observing from these two pics, their movements look a like! stefan...
I'm completely out of my depth in these waters, Stefan . . .
. . . as I came to Glashütte Original only in the last nine years. I don't think I've ever seen a vintage GUB outside of the Museum. A few must've made their way to America (Steve G has one), but their profile here was practically non-existent until the s...
Movement differences
Hi Stefan, beautiful GUBs you have there! I almost got my hands on a very nice sample of the "Sixties", but unfortunately "almost" only. The difference between cal. 69.1 and 70.1 is that cal. 69.1 features the date while 70.1 does not. (Btw: cal. 67.1 is ...
One more difference
Hi Stefan, relooking at your pictures I saw one real difference that I overlooked the first time: The cal. 70 has screws in the balance rim. That makes it the higher quality cal. 70.4 instead of 70.1. (hard to tell a 4 from a 1 in the picture.) Best, Mart...
yes, that is another difference...
... i saw that, the additional screws in the balance rim usually came with the high quality movement. thanks once again, Martin. stefan

feel happy with my GUB chronometer after....
... after reading your informative post. learnt some more thing new. thanks very much for your valuable input, Tom. stefan
I don't know why...
GUB changed their numbering system from the 60 series to the 70 series. For the 60 series, they distinguished the "1Q" movements with a different number: GUB 60 - small seconds, basic GUB 60.1 - sweep seconds, basic GUB 60.2 - small seconds, Guteuhr GUB 6...
thanks once again, Tom...
Tom, really appreciate for your additional info. by the way, where did you find these excellent data? would like to learn more from you. stefan
Ditto . . .
. . . and I wouldn't be surprised if there are caches of these movements waiting to be cased. Spezimatic movements are used by the boutique watchmaker VDB . . . . . . cordially, Art...
Art, the case shown in your pics....
.... that looks really nice and stunning. can tell us a bit more what is that watch? any pic of the dial, please? stefan
you can look...
...at two particular German reference sites (noncommercial) for Glashütte movements; I'll send by PM as I'm not sure about posting them here. You can run them through babelfish or break out your German dictionary! I got interested in the vintage Glashütte...
received your PM, thanks...
... i think all these GUB vintage watches are understated. but i am sure there are some collectors collecting these simple and accurate timepieces. for modern German watch, except Lange or GO are most popular, others very good ones, like UG, Nomos, Stowa ...
Thanks for the detailed response, Tom. My understanding was . . .
. . . that the Dornblüth 04.0 was based on a 1950's GUB movement, and I recall seeing a photo of one of the stock movements they acquired prior to performing any work . . . the transformation they wrought was near miraculous!
I think that's right, Art
...as the GUB 60 series was in production from 1952 to 1961. The "1Q" versions of the movements were produced beginning in 1954 and made up about a third of total 60 series production. I believe Dirk kept the wheel train from the GUB 60.x movements and pr...
Thanks, Stefan.
Indeed, they look like Quality Movements, well, simply built. Serious. Best, my friend. Nicolas
