Thanks for this summary of an excellent piece of connoisseurship. The 1st generation, 2nd execution still has me scratching my head.

 

I agree on the overall nomenclature - 1, 2 and 3 generation, and also about the first and second execution of the first generation. Thank you LouS for sorting things out - it will make future conversations easier.

I hope to stir things up a little in the near future by the publishing of a Polerouter Sub dial that does not fall into any of the above generations or executions. The form under which this dial came to me makes it most likely an original and very probably a prototype. I do not think that there will be any need for a third execution because of this dial - as I have not seen another one. I will let you be in suspense for a while (need to take some clear photos).

When it comes to UG divewatches - apart from the polerouter, I would like to put forward the Unisonic Sub. Not a polerouter - but nevertheless it is a UG Sub. A colourful addition to any collection and there is a resemblance to the Zenith 1000m that I think would make it extra interesting to us who are into both brands (vintage).

These are to me some of the most mysterious UG when it comes to understand their chronology, generations, executions, ... and despite I spent hours to try to understand them well, I have to confess I'm still confused

Maybe this thread will help ?

We're all aligned with the Super Compressor case ones as being the 1st Generation,

I always thought this one was the 2nd generation, I call it number 1 for the this thread



and this one a 2nd execution within the 2nd generation, I call it number 2



I thougt this one was an alternate case version in the 2nd generation, I call it number 3



Having a closer look on the movements can offer some clues, before posting this, I took time to check on Ranfft website (http://www.ranfft.de) to discover some nice specs sheet

found in the number 1 is Caliber 69



here's the Ranfft specs sheet, showing a caliber produced from 1962 to 65



in the number 2, Caliber 1-69



Ranfft specs sheet showing production years from 1965 to 70



in the number 3, Caliber 218 (although I don't know well these symmetrical cases Polerouter Subs and can't confirm this movement type is fully correct for that generation of Subs)



the 218 Cal. specs sheet showing production years from 1960 to 1962



Based on this we could say Number 3 could be a contemporary alternate version of the Super Compressor case,

Number 1 a second generation and number 2 a third ?

This hypothesis could work if anybody knows if the number 3 received others movements or not and the fact UG made "clean" production lines (the right movement in the right generation).

Cheers,

Hi everybody,
I'm realy happy to see this new forum about UG
My first post is for illustrate the complete post of my friend Noodia, you can find pictures of, thank to him, my POLEROUTER SUB :
Full set with original box

Beautifuf black Dial

 

it would also suppose UG productions were consistent at the time which I doubt

Thank you Jerome for such a nice bunch of pictures !

 

Situation looks different from Europe,
never seen a 1st execution below $3500 maybe more likely in the 4K region, sometimes more, I'm no expert in these, I couldn't tell exactly with regards to variations,
asymmetrical cases are in the same region

 

Don't take this the wrong way mate, but it looks a bit Australian to me.

 

*sigh* I specifically wrote don't take this the wrong way.
