Dream watch
This
Seiko ref.
4580-7020 is usually called the
“Imperial V.F.A.” (short for “Very Fine Adjusted”).
Its dial features, at 12 o'clock, the Imperial crest of Japan or Chrysanthemum crest (菊紋, kikumon): a circular flower comprising a front set of 16 petals and a rear set of 16 other petals semi-offset from the front set and visible on the edges of the flower.

The
"Imperial V.F.A." shares the same
cal. 4580 movement found in the
Very Fine Adjusted refs.
4580-7010 and
4580-7000 .
Some of these movements were included in submissions to the Neuchâtel Observatory for chronometer testing in the 1960s.

The "Imperial V.F.A.", with the Imperial seal flower on the dial, was made exclusively for Emperor Hirohito (裕仁; 1901-1989), posthumously honored as Emperor Shōwa (昭和天皇, Shōwa Tennō), who gifted it to the people who took care of him during his first trip to Europe in 1971.

The
crown is
unsigned.

The
case shape is similar to the one of the
45GS.

The
case back is engraved with “
Nippon Seiko” only, rather than the customary “Seiko Japan”.
How Shadi AH acquired this absolutely amazing
watch is
told by himself in this
article for Sjx:

It is said that
only three examples have ever been
photographed.
Here’s the only other one I could find, hoping that it is genuine and not fake.

And I also found a
slightly different ref.

I absolutely love this watch. What about you?
Thanks for reading.
