Mr. Akira Ohira: "... Before GS, I was involved in assembling and adjustment for the Credor Chronometer, with 4S79 movement in 97, LE of 500 (note: to be precise, there was another special LE version of this caliber for one of the retailers, LE of 20, so the total number is 520...). I did it alone.
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."
