The 44GS series evolved from the King Seiko model produced by the Daini Seikosha factory. Only on sale for two years, it was introduced in 1967. The 44GS is significant for introducing what is now called the Grand Seiko “Grammar of Design” (aka G.O.D) case 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  with the text “Diashock” printed beneath “Grand Seiko”. This was soon changed with the “Diashock” text removed and replaced with the logo of a lightning bolt that is the logo of the Daini Seikosha Kameido factory which was located in Tokyo, Japan. The low beat 4420B caliber is considered by many Seiko enthusiasts to be one of the greatest manual wind movements ever made by Seiko. The iconic Daini balance bridge with the clean finished plates make this movement a beauty to observe.

 

Overall, this piece is in excellent vintage condition. The case and bezel has some bumps but we believe it has never been polished with just natural wear. It retains its sharp edge and a beautiful Tanaka grammar of design profile. The original silver dial is in clean condition with very few visible blemishes or spotting on the dial. This is the late dial variant as can be seen from the lightning logo  under the Grand Seiko logo. The handset and crown are all original and in excellent condition. The movement has just been serviced by our watchmaker. It is running at -2.6 seconds / day and will come with a 3 month movement warranty. The caseback is well preserved and the original gold medallion is in fantastic shape with just some minor aging along the letters.
