 Overhauled, beautiful 1970 Seiko KS Superior Chronometar Officially Certified Hi-Beat hand winding watch.

Caliber 45 ticking at 10 beats per second, is considered by many to be Seiko's finest hand winding movement.

NOS genuine KS acrylic crystal.

New Seiko black leather strap.

Genuine KS buckle available for additional 15,000 yen. 

Case is curvy and edgy at the same time and it is in very good condition. There maybe some minor fine scratches here and there. 

Dial is beautiful and nearly flawless. 

There is a slight, small blemish under "ia" in Officially. It's hardly noticeable, camera didn't even catch it. Tiny spot that appears to be little less shiny than the rest of the dial. Could be that some solvent, like alcohol or benzin, made a contact with it. 

Movement is clean, healthy and runs very well. 

It takes about 60 turns to fully wound the mainspring and power reserve is about 43 hours. 
Daily difference is within 5 secs.
