Jeg har tre Credor, har delt bilder av de her på forumet, men det er nok seks-syv år siden. Så da er det på tide med en liten reprise til glede for nye og gamle lesere.
Seiko Credor GBAY992 fra 1997, eneste chronometer fra Seiko på denne siden av 1980. Urverket satt sammen av Akira "God of Adjustment" Ohira, her er hva han fortalte til PuristSPro om når han bygget disse:
"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."
