Here are five pictures of the watch:
#1: Comparision between the Time Computer II Constellation, Omegas first LED and a standard Time Computer II. As you can see the TC2 is quite small (and in heavy used condition
)
#2: View of the Omega and Time Computer lettering
#3: Without clasp you can see in the inner part of the bracelet. These are hollow type links, only the first 3 links are solid on each side.
#4: Inner side of the case
#5: The watch did not come with a module and the seller said the prototype has been unfinished. That´s reasonable as the button does not contain a magnet yet. I was quite sure that the watch has been produced to run with an E/D module. The calculator watch modules have the same dimensions as a P1.
#6: And here´s the proof as the calculator module is a perfect match.
