Watch accuracy apps

So my question is does anyone use watch accuracy apps to check how accurate their watches are over twenty four hours

And if so how accurate are the apps only asking as I timed a watch over 24 hrs using Apple app tool watch and the result was ..................

+8 sec over twenty four hours on a auto movement is that acceptable on a watch

i think 8 secs is more than acceptable, but then i am not too bothered about accuracy, as long as my watch i am wearing is within a couple of minutes over a couple of days i am happy.
i rarly check absolute accuracy......mainly because i am lazy, but quartz accuracy interests me from a technological point IE the Seiko 9F movement which is accurate to around 10 seconds a year..now this amazes me, ETA do the Preci drive which has similar accuracy but not the quality or Longevity of the 9F
i think the last watch i timed was my Pantor Seahorse with the Miyota 9015 movement and it came in at around 4 seconds a day which apparently is not unusual for a 9015

Just under a minute over one week on a auto I would say is fair in my mind but as you say I may try a few off my Quartz just to see how they fair up , i will try my g shock as that is supposed to be pritty accurate let the test begin result in about 24 hrs hopefull lol

I'm going to time the watch I'm wearing. It's a quartz chrono sekonda. I've got a feeling some of my slightly older watches might do quite well if I timed them

So result of the g shock rangeman is drum roll please .........................................

+1 sec over 24 hrs

i would have expected better to be honest
could the 1 second be the reaction time from you starting and finishing the test.....if you think about it its only 0.5 seconds a side??

Yep I'm guessing it's my reaction time to be fair

it doesnt make sense otherwise as that would make the watch gaining 365 seconds a year which for a branded quartz would be really bad, i think you would need specialist measuring equipment for a quartz over 24 hrs so maybe a test over 2 weeks would interesting

This could even revert back to my original question how accurate are these apps ?

i am guessing its only as accurate as the user.
i seem to remember these promoters of this App getting some abuse for the idea when they first introduced it, there are too many variables in the test to be accurate, they may connected to an atomic clock [ are they ? ] but there will be a delay however small between that and your PC, Laptop or Phone etc then add the human element and it cant possibly be accurate which makes the App completetly pointless.
i use my PC clock to check and adjust my watches, its probably a method thats a few seconds out, but is as accurate as the App and is as good as i will ever need.
i have now recieved [ probably their first of many ] promotional email trying to sell an over priced watch winder and i suspect this is the purpose behind the App all along, just a method of gathering emails and potential sales..i have unsubsribed
for us guys i think the most accurate timing method would be the talking clock, i quick phone call gets you access to the pips from the Atomic clock and you can see where you second hand is in relation to the pips..........sadly it now costs to phone the clock
