Okay, so i was reading a thread that has seiko new release. Then i got into a comment that says
“Anywhere from -10s to +15s a day. … I was ok with that accuracy when their divers were $400, not $1k+.”
So i really wonder if this statement is actually true, that 1k watches have better accuracy than +15/-10 Sec. Does watches in this price range really state their accuracy and have good accuracy that makes Seiko watches look over priced.
This Thread doesn’t care about YOUR certain model current accuracy, im taking what the manufacturer said (or if they don’t say anything) it has. Because same thing can be said with Seiko’s product, seen some of their Low end budget movement have really good accuracy. So your Watch accuracy is irrelevant here.
So Lets go!
Let’s start with this sub favorite Tissot PRX doesn’t even state the expected accuracy of the watch. Since its not chronometer certified according to the User Manual:
“Most watches which are not certified chronometers have an average accuracy tolerance of around -10/+30 seconds per day”
this thing cost around 500-700 bucks. Tissot doesn’t state the accuracy of the watch but they do imply on their manual that its -10/+30 sec per day because it doesn’t have any chronometer certification.
Another favorite watch around here, Hamilton Khaki. Hamilton also didn’t make any claim for the watch. That watch cost u 1k usd. According to their FAQ page: “Most watches that do not have a chronometer certificate have an average course deviation of -10/+15 seconds per day.”
Now lets go to Christopher Ward The Twelve. Another 1K+ watch, using a selita movement. Accuracy Stated in the Website Page +/- 20 Seconds.
Then we go to Doxa, another favorite brand in here. the Sub 200 professional. Another almost 1k watch. No stated accuracy.
Lets go a bit Highend the Longines Conquest. Almost 2K watch, using L888 Movement (this is not COSC). No actual stated Accuracy too.
So I guess the Seiko stated accuracy is about par for the course for most major brand. Its not really worse than other brand that sells their watch at higher point and didn’t disclose their accuracy number (which IMO is worse).
So my question would be, why does it always comes up on seiko products the criticism on their movement accuracy but never on other brands?
Maybe seiko should stop posting their accuracy number all together, so they would have a better brand perception, since lots of other brands did that and escape criticism.
Or is it because of the Swiss bias? Since the movement is Swiss there for its fine because surely swiss movement is higher in quality.
Either way this is what I find, feel free to correct and add to the discussion.
Personal Rant: if accuracy is so important why don’t u just buy a 50 bucks quartz and be done with it instead of going into mechanical watch.
First off, Seiko’s stated accuracy for their 6R is actually worse than what you’ve listed.
Source: Seiko’s own technical specs say +25 - 15 seconds per day
Your post is interesting but I think it is fundamentally flawed. The “stated” accuracy of these movements straight from the factory isn’t the only factor to consider. Many of the brands that use ETA, Sellita, STP, etc will perform modifications, service, and add custom parts to these movements to improve the accuracy and durability of the movement out of the factory. Brands like Sinn and Hamilton do this to varying degrees. It also serves as a second level of QC that doesn’t happen with Seiko.
It’s like comparing a stock engine straight from the factory to one that’s been tuned and slightly modified by a mechanic. They might have the same listed horsepower and be the same engine, but one will outperform the other. Grades are also a thing to consider ex: https://calibercorner.com/sellita-caliber-sw220-1/ Sinn for example uses the SSW-220-1. You might google that and say the accuracy is up to +/- 30 s/d. However that movement has 4 grades, and Sinn uses the “top” grade of movement with a stated accuracy of +/- 4 s/d.
