Me?
It's a real UG Compax but a modern (1987) version with a Lemania movement.
It's only worth around 1/5th - 1/6th of the last in-house references from 10 years earlier.
I feel a little bad for the guys who bought these watches. They were purchasing the reputation of a manufacturer which basically no longer existed.
I have the original store receipt from Tourneau NY and it was $5000.00 (5,182.00, to be precise) with sales tax in 1987 dollars. Ouch.
