The 44GS series evolved from the King Seiko model produced by the Daini Seikosha factory. Whilst only on sale for around two years following its introduction in late 1967 the 44GS is significant for introducing what is now called the Grand Seiko “Grammar of Design”, by Seiko’s first in house designer Taro Tanaka. The very first examples of the 44GS, offered in stainless steel cases with the model number 4420-9000, had a dial print that was clearly copied over from the 5722-9991 with the text “Diashock” printed immediately beneath “Grand Seiko”. This was soon changed however, with the “Diashock” text removed and replaced with the logo of the Daini Seikosha company, giving us the second example of the watches produced in this series. The low beat 4420B caliber is considered by many Seiko enthusiasts to be one of the greatest manual wind movements ever made by Seiko (or by any manufacture for that matter). The iconic Daini balance bridge with the clean finished plates make this movement a beauty to observe as well.

 

Overall, this piece is in great vintage condition. The case has some bumps but we believe it has just been polished once or twice in the past given that it retains sharp edges with a beautiful Tanaka grammar of design profile. The original silver dial is in clean condition with only minor spotting on the dial visible under a loupe (see macro shots below). This is the early dial variant as can be seen from the “diashock” text under the Grand Seiko logo. The handset and crown are all original and in good condition. The movement history is unknown but is running well at the moment and our watchmaker did some simple servicing. It is running at -2.3 seconds / day. The caseback is well preserved and the original gold medallion is in fantastic shape.
