THE REVIEW
Case
Upon its arrival, an examination of the case showed numerous fine
scratches and scuffs. Most are not noticeable under normal lighting conditions, but a few do stand out. I’m guessing that this is a job
that would exceed the capabilities of even Judge Crater’s toughest
patch. The top surface of the acrylic cover is clear, while the four
side surfaces are lightly frosted.
Dimensions of the model (with top cover on) are as follows: Length
(front to back): 87.5 mm; Width (side to side): 138.0 mm; Height 43.5
mm including base.
The base is finished with a coat of white gloss paint. It’s relatively
evenly applied, and there only a few places where minor scratches
(hairline) can be viewed. Many more imperfections which are not visible
to the naked eye become visible under magnification.
To the naked eye, the printing is clear and well formed. As you can
see by the picture below, however, magnification reveals something
entirely different.

The bottom of the base is covered with a lovely piece of felt.
Movement
For those of you who don’t like plastic parts in your watch movements,
this model is not for you. The rotor, along with the two rollers that
ride along the cam, are plastic. There is also a thin plastic disc
covering the winding wheel. The remainder of the model is metal, although
I am unsure of the type. I would guess that it is some sort of plated
brass or similar material.


The one thing that bothers me about the model is the size of the rotor.
Unless I’m miscalculating, the rotor itself is not consistent with
the size of the remainder of the model, which is indicated to be a
5:1 scale as compared to the real movement. If the entire model was
truly 5:1, then the rotor should be roughly 180 to 190 millimeters
in diameter. The rotor in the model is only 78 millimeters in diameter.
Apparently IWC shrunk the rotor in the model to keep the entire contraption
to a more manageable size.
Rotor movement does actually wind the wheel on the model. Each full
revolution of the rotor advances the wheel a total of 8 teeth. Four
of the teeth are advanced by the major click, and four more are advanced
by the minor click.

Overall, movement finishing is quite rough (by IWC’s standards anyway).
This is the sort of finish I’d expect on an Invicta or Poljot model.
The major and minor clicks show considerable machining marks, and
the other movement parts show a cursory surface polish. There is no
Geneva striping, anglage, perlage, colimaconnage, and any other “-age”
for that matter.

As you can see from the image below, a close look at the rotor printing
indicates considerable irregularity. This is not really noticeable
to the naked eye, however.

Overall Assessment
This is a very cool toy, and well worth the money. Everyone who sees it wants to play with it. If I had the choice
to make over again, I’d buy it in a heartbeat.
