Accuracy - is there an average

[SteveA 309]

I have only started collecting so to speak and have a Panerai GMT 21J asian automatic which gains about 10 secs per day ,has a great second movement and looks good.

 

I also have an Omega Seamaster GMT 21J asian automatic which loses about 10-15 secs a day.Again a great sweeping hand and good looking.

 

I have a Longines Hydroconquest Gen Swiss made auto which gains about 10 secs.This is a real looker !

 

Are these good tolerances/accuracies for the movements or should I be concerned about my Gen Longines which cost more than 10 times the others put together ?

The reps are within specs 10-15 seconds either side is normal but the Lomghines should be doing better than that. I would be thinking under 5 seconds a day for that watch.

For a rep, 10-15 secs is good, especially if it's a 21J. Personally I don't worry about 21js unless they're a minute or two out per day. I agree with Col, though, your gen Longines should probably be a bit more accurate than that.

[Del 4,517]

I agree, 10-15 secs/day for a 21j is good. I have one or two that are worse than that, although most are in that range.

Thx for the replies ,maybe its time to get the Longines serviced.

I set mine, waited 24 hrs, set it again, waited 24 hrs, then set it again. On the third day it was 1 second fast at 26 hrs. Which is basically 2 minutes a month. I think that's acceptable

 

Out of the box I found what I thought was perfect was actually 5 sec fast per day.

 

So in summary, you can make it basically perfect, just takes a few days.

sorry, between this monsoon of a heater and that, it sucked, but i swear, they are dead on!!!

 

i couldnt record the vid with thte phne cause the phone was the basis for the settings. so i had to figure out how to use the webcam (which BTW is the first time i have EVER used it) to get this vid.

no need to apologize - you refreshed it in time - excellent luck with the accuracy

 

I change my watch nearly every day so accuracy never worries me

[SteveA 309]

set mine 2-3 times as rec ,gave it some regular wear and hey presto running about 1-3 secs fast which is fine and a vast improvement.Note to self;"Do not neglect automatics"

Thanks for the advice.

still dead on after a few more days just checked.

My new Pam 203 gains 30 mins in 3 hours!!!!

It's a j21 I think. How do I attempt to slow it down. Is it difficult?

UPDATE:

 

ok, today is the 7th of march, and i just checked my watch to the iphones clock, i am EXACTLY 12 SECONDS off. so from 19thFeb, until 7thMar, i am only 12 seconds slow!!!!!!

 

so i am losing 12 seconds in 16 days!!!!! that is less than 30 seconds a month. and i wear it every day, all day, regardless of activity, and i sleep with it on. i have even showered with it (and no, i didnt waterproof it or anything) with nary and issue

 

god i love this watch!!!!!!!!
