 Serviced, rare, green dial GS with faceted crystal from 1972. 

NOS Genuine Seiko faceted crystal.

New Seiko crocodile leather strap resembling the original. 

Case is sharp and in good condition with some minor scratches. 

Green dial is beautiful, but unfortunately not flawless. On the edge, below 6 o'clock finish fell off. Why and how, I don't know. There are no signs of moisture damage or corrosion anywhere. There's also a small blemish to the top right off center, only noticeable on certain angles. 

Movement is clean, healthy and runs very well with very good accuracy. 

Plastic star for calendar quick set, the weak point of this caliber, has been replaced with metal one.
