I have never really seen another UG Tri-Compax with this style of case. Can anyone lead me to a set of correct hands ? What do collectors here on OF think of the case ? The third picture I'm trying to show the two facets on the top of the lugs. Sorry for the low quality of my pictures !

 

Looks like an HJ Case to me.

 

I've seen that case on a Compur, but never in a Tri-Compax ?

 

My first thought as well, looks like a fairly polished HJ case. What's the case size and cal? Should be easy to check the hammer hallmark on the caseback to verify 166. Looks like a nice dial.

 

Doesn't and 815 serial predate the early tri compax?

 

Well, this example doesn't seem to be a modified case. Pushers for adjustments work perfectly. Nothing seems abnormal. I've had this watch in my collection for a very long time. Before the UG popularity of late.

 

It would be quite hard to modify the HJ case to fit the date, month, moonphase buttons perfectly. However the case back I am not sure, they are probably interchangeable. But still why would someone do that?

 

I was going to say, if it's not a tri case, someone would have to do some impressive work with the 3 correctors

 

Pictures of the movement and inside of case.

 

Oh I'm not saying it can't be done, for sure, it's just the unbelievable trouble I go through trying to get even the most basic things done for my UG watches, if it was a MOD, I would love to hire this person to work for me. I've been waiting like 3 months just to try and get some very basic plating work done.

You would need the donor correctors, both internal and external (I suppose those could have come with the mvmt). Seems like a lot of trouble to go through?

 

So it is the earliest known costumized Tri Compax in the wild

 

I think it's original UG Tri-Compax, doesn't look modified at all Lou, could it be a custom job from UG directly ? Pushers are perfectly aligned.

 

As UG goes it's somewhat unpredictable !

 

Looks cool! There are so many variations of these older watches it's hard to know for sure, but if legit looks great!

 

I've owned the watch for probably 20 years.
UG was not that popular for somebody. to go to all of this work to produce this ?

 

Just read this all the way through. Correctors don’t look factory made. Modified case?
