Does it matter how accurate your watch is?

As long as its within spec.

Not terribly. My automatics usually power down by the next time I wear them, so I set it again using my G-Shock atomic time

Would you know if it wasn't? I'm not sure if I would notice a minute a day to be honest 🥺

Exactly the same. Yet I'm impressed by and pay more for COCS watches. Am I gullible or does it have value?

I'm the same as you. I can't be arsed about accuracy of my mechanical/automatic watches, but will be seduced by COSC certification on watches.

I second the motion of @Dsoeer. If it goes faster or slower than the standard deviation stipulated in the manual, that's the time I will be more concerned.

I too rotate my watches quite a lot to not be bothered about accuracy.

The only chronometer watch I owned was the BB58 and it was running about +4 seconds a day and at the end of the week it was about 20-30 seconds fast. Regular COSC certification seems to be a value added but it is pointless when you have multiple watches and the watch is deemed to run out of power by the time you return to pick up the watch. But if its your only watch then COSC is good.

If accuracy matters I would just stick with quartz and I always end up picking a G-shock or my other quartz watches for a quick grab and go option. If the smooth sweep is a criteria then Spring Drive is the best bet for accuracy.

I never set mine accurately in the first place so it doesn’t matter to me. 😅

Yes absolutely! That's why I spent a small fortune on an Omega (it is the biggest purchase in my life except for motorcycles).

Not because I need it, but because it blows my mind that these little machines can be so incredibly accurate, I was in the position to buy what is in my eyes the ultimate mechanical watch, I'll never be able to afford the best Ferrari, yacht or mansion but I could get my Grail watch so I did.

I wear it almost daily and it's never more than a couple of seconds off. That's incredible & why accuracy is important to me. Not coz I need it, but because I can have it.

Hope that makes sense 😁

I kind of feel the same although I took a Rolex in for a service and apparently it was in dire need of some TLC.

It was loosing around 30 seconds a day apparently and I hadn't even noticed! If it hadn't been for a loose rotor rattling about I probably wouldn't have ever known 😕

Accuracy is a nice little bonus but not something I care about much or that would motivate me to go upmarket. I like to change my watch every day or every other day so I never notice them deviating much anyway and they just run out of power in the watch box at the end of the day. Movement specs are 90% fluff to me.

I can’t really add to the discussion owning an SBGN003.

I’ll be back when I get my grail.

As for my PRX Auto it reliably loses 5s/d and I don’t care, really.

Ha, none of my mechanical watches hack, so until it gets to a minutes-per-day range, I won't know or care.

Accuracy (mechanicals) is very important, probably 25%-35% of the decission.

If it don't keep good time, it fails as a watch, imho.

PS: It really boils down to how does the watch do accuracy wise when worn on the wrist and let run over night. Not so much published specs in magazines derrived from a tming machine but real world results.

My week day watch is a solar quartz and very accurate so it doesn't bother me much. My automatics are usually worn after work or on weekends and for those times I usually just put them on time and they are precise enough for the time I wear them. I think it would matter more if I had only one gada watch always on wrist I would like it very precise. But it's also fun for me to set them correctly once in while. It connects you to your watch. So to some it all up I don't think I'm bothered at all if a watch isn't super accurate! If accuracy is very important Quartz is the way.

I found that if you have a difference of 15-20 secs a day, after one or two weeks your watch is “out” enough need resetting, and that feels frustrating. With the more more expensive cosc or equivalent, this effect never seems to get significant enough to notice before I switch watches etc

Accuracy is very important to me but then I've got Aspergers. Those kind of things get on my nerves.

I rotate often and always compare time to atomic clock and adjust. I do look at caliber reliability and performance when I buy a watch but I have never purchased a watch solely on a movement.

I am more interested in timing the power reserve after a full wind and wearing my auto all day.

Not at all. I don't understand the obsession over it for some. Honestly.. Who cares if it's off by a bit? If you need real accuracy, use the device in your hand right now, your phone. I've said it before, watches are functional jewellery that happen to tell you the time. That's why whenever polls come up here the #1 answer on what's most important to everyone is the design/look.

It depends, if you wear different watches in a week then no. But if you wear the same watch everyday, then yes, it does matter.

I don’t really care that much about accuracy. I have no use case in my day to day life that requires accuracy to within seconds.

I had a watch that was off 5 minutes every hour lol not great

Used to be quite particular about accuracy but did not bother me much after a while especially getting watches without second hand 😂😂

I have absolutely no need for a watch to be accurate to less than a minute or two a day, but I consider accuracy as an indication of the quality of a watch, and therefore it usually becomes an important consideration in my decision making process when looking at a new watch. As price goes up, so do my expectations.

For different uses, I have different expectations.

Dress - accuracy not an issue

GADA watch - Must not be slow, and less than + 10 seconds per day

Digital beater - must be very accurate as I use it to set my other watches

Anything else - within spec is fine.

Accuracy only matters if I paid for it or not. If I buy a chronometer certified then (under warranty) it’s what I paid for. It’s importatnt to educate myself on what I’m buying - I’m not in position to spend money I’ve earned, like it’s about to rot so every purchase counts. If I buy a vintage watch, then I expect the same accuracy/spec as a brand new chronometer

No,,i pick up a watch, check the time on my phone n set it.

I have OCD tendencies.

Sunday night ritual is to sync all my autos to my GShock GW6900.

Am I annoyed that my COSC certified watches are 7 secs off by the end of the week, yes.

But I guess it’s part of owning mechanical watches.

Just bought a Grand Seiko quartz and am now testing real world use. Will see if it measures up to the GShock.

Only if your life depends upon it 😆
