[SEIKO] Grand Seiko 2nd 5722-9990 Chronometer notation Final manufacturing date

A second model of Grand Seiko with very many small variations.
The chronometer notation of the dial or the GS notation is roughly divided into the latter half of the previous term.
This is a little geeky item, the final date of the chronometer notation.

This watch is overhauled at our shop.
Comes with Grand Seiko buckle.

Bezel diameter 36mm vertical 42mm width 39mm (including crown)
(Wearing model men around the wrist 16.5cm)
