Same here... While they may be accurate, there is no way one of those will still be working fine in 15 to 20 years or more like a good quality quartz or mechanical watch!

For accuracy, my Casio Atomics cant be beat. My ArmourLite is very accurate too. I would guess no more than 30 seconds late a month.

I own Rolex, Seiko, Sinn, chronometers all.

I have them regulated. In the case of my Rolex YM and Sub Date, they are both accurate to +1sec/day.

My Seikos with 8L35 and 6R15 and 6105, they are just under 2+sec/day.

It can be done, you just have to be patient and work with a good watchmaker who will take into account the basic error, your lifestyle and if you wear it 24/7 which I do.

My Sinn is argon filled, has the 7750 in it and is 9+sec/day which is unacceptable for me personally. I will have to ship it off and hope for the best and try to contact the watchmaker to fine tune the adjustment.

It's an effort, but worth it IMO.

Any decent quartz ought to be +/- 15 to 30 seconds a month. The best quartz can be 5 to 10 seconds a year. The best mechanical watches will be accurate to about 5 seconds a day, maybe a little better.

Is your Marathon quartz?

Honestly, the more I got into watches, the less I cared about accuracy. I'm just simply amazed that most of my mechanicals can hold time to within about 2 minutes after a month. This is basically a spring releasing its energy through a miniature gearchxain. Hell, my Speedmaster is a manual wind movement with a 48 hour power reserve - I wear it because I enjoy having a micro-machine on my wrist.

FWIW I was recently made aware of Time.is. It’s interesting, check it out, it also gives Unix time ( I’d never heard of that before). Poke around on the site, click on the “About” link at the bottom.

Just another way to get the exact time.


I just checked it against my watch. My watch is precisely in sync with that site.

I have a Casio G-Shock solar/atomic that is accurate to within a half second per day. It cost me $80.00 about 14 years ago. It is still running without a problem. I also have a Citizen World Time solar/atomic that is also just as accurate that I have had for about five years now. It cost $279.00 if I recall correctly. I set my other watches by one of those two once a month or so. My Isobrite watch runs about two to three seconds fast per month. That's pretty good for a quartz watch.

As I mentioned in the recent Marathon thread, I've got a Luminox quartz that I've owned for several years and check/ reset the time (against the time.gov website) at the beginning of each month, and record any errors and adjustments. The first movement started out @ 8 seconds fast per month but seemed to settle into a 6-6.5 seconds fast per month for several years. The movement was replaced last year and this movement is @ 6 seconds fast per month although I'm trying a 5 second offset this month to see how it compensates for some small discrepancies.

Back in the mid-'80s I bought an auto Seiko dive watch as my pilot's watch, and absolutely loved the watch for the movement I could feel as it wound itself and the way it looked on my wrist, I received a lot of compliments on it...but reliability and accuracy wise it was a terrible watch...and it spent almost as many days being repaired under warranty than it did on my wrist. After the warranty ended and the watch quit working yet again I shelved it.

I've always been a bit leery of owning another auto although I'm fascinated by their movements and drawn to them. Stories of their relative inaccuracy have also caused me to shy away...but if I could get an auto to stay within +/- 5 minutes/ month I could live with that.

Would you expand on what is required to regulate to the kind of accuracy you mention? Are all auto movements capable of accuracy regulation, or only certain ones? Just a ballpark figure would be helpful, but is pursuing this level of accuracy an expensive pursuit?

A Speedmaster Pro, especially a vintage "moon watch" is on my dream list. What kind of accuracy do you get from your watch?

25+ year old Seiko dive watch, battery power, is as accurate as my Apple Watch (which I don’t wear that much).

The satisfaction I get from my automatic watch with a Swiss movement that keeps +\- 2 seconds a day accuracy is immense. For a machine to have that many moving parts, beat that fast and still keep such exquisite time....I love it!

A common joke, but false. I have one Rolex and it is the most accurate mechanical watch I have, by a very wide margin. They are overpriced, but excellent watches.

Radio synchronized watches are not accurate. They just know how to reset themselves. They are no better than average when unsynced. Why put an accurate timekeeper in there? It is a whole different way to skin that cat.
