to be honest, these practices are already done by seiko and citizen itself and for models already for sale in the last 20 yearsI am very impressed
Most watch-manufacturers try to brain-wash me with stuff about horses or what watch Churchill wore. They invest in the perceived value of the brand-name rather than the quality of the product.
Citizen list some expensive procedures which make me think that they have engineered the watch to meet 1spy with a high degree of confidence -
> pre-aging of xtal & selection of best-performance examples
> individual measurement of temperature characteristic
I also like the achievement of precise hand-alignment (emphasised by a simple dial without date-window).
What struck me was the statements :-Except for the doubling of the TC table, I did not see anything that was not already known.
Assuming the compensations needed on the crystal are fairly linear over the desired temperature range, you need two things to make TC more accurate: more significant digits in calibration (by doing longer calibrations) and finer increments of adjustment. This will give you a more accurate inhibition count for each individual crystal....
I wonder if they double the TC table by doubling the number of test-points, or just by doing more interpolation.
Don't hold your breath. Obviously, we don't know, but I use the Eco Drive One as an indicator...similar custom tech, high end, limited market. 6000 for the initial LE, only dropped to about 2600 or so with the latest models. (Which can sometimes be found for < 2000.) But the black dial 0100 LE is 20% higher. Worse, there's nothing about that model that suggests there will be a big price drop, other than perhaps a less expensive bracelet.I can’t wait for this tech to be < $2000
Loki posted a long term accuracy graph about his Chronomaster.As I remember our data, it seems age is not a factor even at high accuracy after a year or two.
“Life in the Fast Lane” (1976)?? Nah, that's not me anymore! (Just turned 72.) After a life of collecting sports cars, I now own the fastest car I've ever had and I've never had it more than 20mph over the limit LOL...
What was that Eagles song again?
So the Maxim folks are spec'ing to about 60 spy for their chip... (Did I read the spec sheet right?) And the aging corrections are externally generated?
Loki's data is one of the pearls of the internet.
Sabresoft is another long term one.
About the caliber 0100: It all depends on the fine print. 1 second per year can mean absolutely anything.
But I admire Citizen for daring to go all nerdy. I mean, gears accurate to one micron?
I am interested to see how far one can get, if no expense is spared.
I am now testing a $1 HAQ chip. A DS3231. With, and that fortunately brings us back to the subject, an aging register. I still need to read up on what it does though.
A vintage watch case advert? That's as close as you can get?
Close enough. An advertisement Google did not get their hands on.
