My own physical exam.

Pics to come when she's presentable.

 

Thanks for putting this up. Will be a good reference.

 

I plan on getting the book by Sala (regardless of whether a UG is my next purchase or not) but I gotta say, the knowledge displayed and shared by some of the venerable members here is mind- bogglingly good. And I love being able to soak it all up as I slowly put my finger on whatever the next purchase will be.

 

I think F comes before E as F is the first state around 1965 though most pitch at 69 or early 70's...............................mine serial numbered at 1965. think the design did not go down well so changed for even number dial........................bears closer resemblance to D than E.........................

 

How did you peg yours at 1965? I'm not aware of any serial number tables that are that precise.

I've cross referenced the serial number on mine with the tables appearing in 100 ans, which were later reprinted in Sala, and my serial falls between 1963 and 1965.

I believe that chronological dating will be difficult to do without a wider sampling of serial numbers for all of the presented examples above. I'd also note that the F's hour, minute, and sweep second hands are a radical departure from the "typical" UG design (as are the hour and minute in type A, for that matter).

 

serial number on mine(no longer mine) as yours ,indicates '63-65.........................because the hands are so "different" (and hard to read) I believe that the even number dialled Aerocompax replaced after one year.................can't prove it though..............I prefer the odd number dial as I know of no other odd number dial chronograph..................I sold to purchase a Breitling Unitime 1765-another chronograph with venus 178 movement (24hour).

 

Just thought about adding some movement pic as received mine today, the engraving in case back has faded but still viewable (sorry for the iPad pic, I am really no good at taking pictures). And I am not lucky enough to have the original crystal

 

this is mine

(Type B) 12-hour two-tone dial - ref. 22704/3 sn 2358253

 

Phenomenal! Love those blue, blue hands.

 

Ooer! This thread has been a long time coming. Thanks!

 

I'm sort of curious on what makes these 12-hr variants an 'aero-compax' though. The 24-hr variants I can understand (since you now have the 2 time zones), but what about the 12hr models?

The first one of the family... with band and correct bracelet
I mean that's the UG V72 most rare today
