[Rare] Grand Seiko Second Model Early Type 5722-9990 Lion Medallion W SEIKO Crown Cal.430 Hand-wound Overhauled Made in Showa 40/1965 Seiko

This is Japan's top-tier Grand Seiko Second Model.

Production of the Grand Seiko Second Model began in 1964, four years after the First Model.
Compared to the First Model, a date display (with quick-set function) was added.
It featured a screw-down case back, achieving 50m water resistance (at the time of manufacture).
Practicality was improved.

This particular piece features a Lion Medallion on the case back, making it a rare Second Model with limited production.

The dial is an early type, with "Grand Seiko Diashock 35 jewels" printed at the 6 o'clock position (later types changed to the GS logo).
The applied markers that were printed on the earliest dials have been abolished, resulting in a cleaner design.
The indexes and hour and minute hands are multi-faceted with a mirror finish on the surface, giving them an elegant sparkle.

The case material is stainless steel.
The thicker lug design also improves durability and gives it a substantial presence.
