 Serviced, very rare 1966 Seiko Seikomatic, 30 jewels automatic watch in beautiful condition.

The unusual, four-leaf clover on the dial of this Seikomatic is said to signify "luxury specifications" and "rarity" in the design and is generally considered to be a symbol of good luck. 

 At its heart lies the Seiko caliber 8305B, a 30-jewel automatic movement operating at 18,000 beats per hour. 

Movement has been completely stripped, cleaned, lubricated and regulated to run well. It's well engineered movement with all 30 jewels being used. It has automatic and manual winding and calendar quick set. 

Pull the crown one step for date quick set. 

The watch is in good condition, with minor signs of wear consistent with its age.​
