Hello,
this is my first post on this forum. I already tried to ask elsewhere, but so far I didn't get any response. Perhaps it is a well known function, perhaps it is just an "easter egg". Perhaps the caliber 8F32 is rather out now. Anyway, this is my original post:
I am looking for any information about functionality I incidentally found when setting time on my 8F32 Seiko watch, specifically about the "5 seconds dwell on 1st click" function.
What I am talking about:
Commencing on the 2nd click position, push the crown in to the 1st click position, wait for 5 steps of the second hand (= 5 seconds), pull back to the 2nd click position, and see. Obviously it shows a stored value and allows you to change it.
Practical simple example:
Say it is 7.7.2014, 8:30. Date dial ring displays "7", the current date.
Perform the "5 seconds dwell on 1st click" as described in the text above.
Date dial ring starts to turn in this manner:
1 second steps from "7" to "9" (the "VALUE")
1 second steps from "9" to "1"
2 second steps from "1" to "16"
1 second steps from "16" to "7" (current date)
If you break the 2 seconds "counting" from 1 to 16 by pressing the crown in from the 2nd position, the current number from the date dial ring is stored to the "VALUE", and the date dial ring is stepping immediately from this number to the current date. Next time you run this function the new stored "VALUE" is displayed.
Perhaps someone who knows can comment both thermal and mechanical load on the ultrasonic motor driving the date dial ring, and also the thermal load on the integrated circuit. Being careful slows down testing substantially, not speaking about the service life of the CR2412 battery, which drains out rather quickly. Obviously the current is out of the battery maximum load specifications. After a while, battery voltage goes down, and second hand starts moving in two second steps. Leaving the watch untouched for few days the battery "recovers", and second hand makes again one second steps.
The meaning of the "VALUE" makes me quite curious. An idea of a correction table with 16 entries comes to mind.
Perhaps it could explain the mysterious speed up of the 8F32 caliber after battery change, as mentioned by several people. And perhaps it is something else, totally unrelated to the measurement of the time like phasing tune-up of the ultrasonic motor. Who knows.
Any comments?
Yours respectfully
