▲ Details of dial text.
▲ KING SEIKO Shield Medallion. This type of gold medallion can only be found in early batches of 44KS, up to year 1966/67. The gold medallion is in nice and clean condition.
▲ 4402A movement is nice and clean. This 44KS movement is the first movement in the world which use a rare adjustment technique by attaching counterweight to the hair spring. AFAIK, there are only two movements that using this technique: SEIKO 44KS and SEIKO 4S79 Chronometer (limited to only 500 pieces). Below is excerpt from interview with Akira Ohira, father of modern mechanical Grand Seiko, nicknamed "God of Adjustment":
"... Like 44KS caliber, I attached a weight on the hair spring to eliminate the position error. It is not a well known method, and those street watchmakers who don't know well tend to think it is "dust" and take it away and ruin everything. I even picked the glue by calling Locktite telling the requirement and they brought a few samples. Even though I assembled and adjusted the watch, I am looking for it in the secondary market but I have never seen it.
Anyway, the idea of weight on the hair spring was on SEIKO's in-house text book - the accumulation of the SEIKO know-how book. It works, but it was actually implemented only on 44KS and 4S79. By the way, GS does not use Breguet spring, but flat spring - this is based on the actual comparison data, believe or not...."Source: Interview with Akira Ohira - Watchmaking "Father" of Modern Mechanical Grand Seiko
