Spring Drive Accuracy. A brief examination for real performance and long answer of if it matters.
Hi All, I want to preface this with I'm not a measurebater. I generally don't really care about accuracy so long as it is "good enough". What's good enough? Enough that I don't notice in day to day life. That's my metric. But I was curious.... Grand Seiko...
Great Read!
Would live to see a few other brands in your challenge. Let's see Patek, AP, and ALS as compared to Seiko for accuracy.
I suspect they would not hold a candle to quartz accuracy.
I am curious, however, about the accuracy of high-beat movements.
This was great.
I can tell you my Breguet 7727 (the 10hz classique), which I adore, is about a 0.5-1s fast a day, so not near a quartz-regulated watch, but not bad!
Love the post..
Great to see that an SD can stand the test of time. What I've been wondering is about durability. I haven't shied away from wearing my SD but I can't say that my lifestyle offers particularly challenging circumstances for the watch. I've been dying to hea...
I can tell that I wear my Snowflake with little care for its well being.
It has been banged, dropped and bumped. I've hammered in nails, smashed garlic cloves and played the back 9 nine, all with no issue. I suspect the IC compensates for any irregularities. The Snowflake, is no snowflake.
Great Post Paul! Thanks for running this test! It is impressive accuracy indeed and i have the same experience with the new SD movement in my SLGA007 which is spot on since i got it over a month ago!
I was actually surprised how good the old movement also did ...
Thanks for this comparison posting
I have several Spring Drives and should do a similar comparison to see how they are doing. My earliest (manual wind Credor) dates to about 2000 and the Snowflake is 2006 or so. No maintenance on either of them but I don't wear them very often now either. ...
"Affirmation is the handmaiden . . .
. . . of consummation." Should a community member acquire a Spring Drive on account of Pauli's post, please let us know. I'm feeling persuaded myself.
Hahahaha!! Much like with Breguet, I suspect I have little influence with members :)
Though, I am happy to be used as someone to blame, should someone need it when "discussing" their new watch with their spouse. "BigFatPauli made me do it!"
The Spirate approach involves a "tail" on the balance spring for ease of adjustment and minimization of damage
That's important as watches are frequently sent in "not keeping time" and need to be tweaked. Especially with a free-sprung balance wheel with no easy adjusting screw to turn. But it's claiming 0 to +2 seconds a day, which first, is not quite as tight a s...
