That is very true. People don't normally buy a mechanical watch for its accuracy. It's traditional. And tradition is a strange thing. It makes otherwise sensible people do strange things. Like buying a mechanical watch. The modern mechanical watch is a celebration of horology. And a testament to the skills of the craftsmen who build them. People buy mechanical watches for the niche of it. When you put it up to your ear you can hear the ticking of the escape wheel. Looking through the sapphire back you can see the balance, the beating heart of the watch. When you turn the crown you can feel the main spring coiling up, giving life to an otherwise still mechanism. It's wierd, but a mechanical watch just has a certain charm to it.

Unless you really only wear one watch all the time, or keep them on winders all the time which I don’t recommend, you probably will be winding and resetting after it stopped long before you notice the inaccuracy. Though customers will usually experience 1-2 seconds slower than what the watch is regulated at

Phones have even replaced household items like clocks, timers, cd/record players, home computers, and so much more. All that convenience is great, but it’s nice to embrace a time where real craftsman specialized in a trade, and art and technology created beautiful, functional tools that said something about the owner.

I’ve had a quartz watch and works beautifully while it lasted. Beyond day lights savings, i hardly notice any deviation in the timing. Only towards the end of its life cycle when it would 2 hours slow over a few days. Worked fine for another year after a change of batteries, but it ended up stopping. Probably just needs a good cleaning and lubing. Never been maintained beyond battery swap. Might even have rusted inside. It is water proof, but it has not been treated well. My father used it for several years and went river fishing with it. It got scrapped up from the rocks there. He stopped using it since it got in the way for him at work, so he gifted it to me. I used it for another 5 years. Plenty of times with it in the pool, ocean, and never took it off for showering.

I've stopped wearing a watch normally, so whenever I rarely actually want to wear a watch for special occasion, it's always out of battery. So mechanical works much better for that use case. Of course for use like this the accuracy of a mechanical watch is completely immaterial, since I'm winding and setting it every time I wear it.
I can live with 10 seconds a day.
I have a Spring Drive, so this is never an issue for me. It’s off by up to 15s per MONTH, but I usually don’t have it running continuously for that long anyway.
In most industries, the more you pay the less improvement you get per dollar. But it's still an improvement. The watch industry is the only one where the low end is functionally better than the high end.
Well, mech watches today is more like an art piece, not just timekeeping device.
I have a Casio watch and I couldn't believe my eyes, when 5 years later I looked at it and was off only 15-20mins. Never changed the battery, never corrected the time in all those years
So many people are hating. It’s not the fact that expensive watches are a “good” way to spend money, but if you can support it and it brings you joy why not, and why wouldn’t you want something that’s more precise but still has the intricate mechanical movement. A quartz watch will be better technically, but that’s utilitarian rather than a luxury

He's just giving another reference. But a Spring Drive is very close to a mechanical watch. Just the escapement mechanism is replaced by a free spinning drive wheel whose speed is regulated by electromagnetism via a quartz controller, which is self-powered. It's still a spring that drives an escapement which moves the gear train.
as for vintage, i can often tolerate their inaccuracy due to their age. i mean the fact that they still run in the first place is a miracle
Did you know these things called crystal oscillators exist? They only deviate a few seconds per month and they're dirt cheap.
My 4 Casios (CA-53W, A158WE, DW-9052, and GA700) are all off by less than half a second per day. Same with my Timex Expedition. If I want a masterpiece of mechanical engineering, I'll wear a hand-wound or automatic watch. It's truly awe-inspiring with how all this complex timekeeping can come from a single spring. But quartz is always superior for accuracy, and always will be. The only thing more accurate is an atomic clock.
Puts a new meaning to the phrase "the cost of time lost" 🤣🤣
Rolex standard guarantee isn't 2 secs per day. It is -2 to +2 secs per day, so the range is 4 secs per day.
Neat how you began with a question, and ended with its answer!
loved everything about this video. Probably the most concise,clear, and to the point explanation of the different chronometer specs.

Got a nice cobalt blue mariner off AliExpress for $8 5 years ago. It's about 20-25 seconds off when I set daylight saving time back/forth twice a year. Plenty good for me, still on the battery it came with.
so I've pretty much always used digital watches, mostly since nowadays they have a ton of features. mine has two clocks that you can set different times on, a programmable chime, 5 alarms, stopwatch, and metronome. it was less than $30 and I doubt it even loses/gains one second per day.

use quartz crystal oscillator so that you measure it in seconds per month instead of seconds per day or maybe... use a cesium atomic clock so that you can measure it in picoseconds (trillionth of a second) per year

Folks who are skeptical about mechanical watches, please try to appreciate the engineering excellence that goes into manufacturing gears and components, mms in size, that tightly fit into a 40mm case and somehow (against the cold, heat, and daily shocks) regulate +/- 1 second per day. The Grand Seiko "snow flake" costs upward $8000 because of this absolute marvel in craftsmanship. Comparing such masterpieces to any quartz watch makes a mockery of those who dedicate their lives to this craft.
My Bulova literally has held perfect time for the past 2 months
Here i am with my self-made watch, a solar-powered springdrive (parts i couldn't make myself were all seiko) that runs just shy of 8 seconds fast each year.
Grand Seikooo! 🥳
As a kid I got 2 hand me down Seiko 5 that run up to a minute off everyday. Drove me nuts having to correct every few days. From that point on I vowed never to buy a mechanical watch again. My eco-drive solar has virtually been maintenance free for years, only adjusting twice a year when daylight saving time comes around.
I'm wearing a tudor ranger. It is COSC certified and gains less than 2 seconds a day. I have a Hamilton Khaki that loses at least 30 seconds a day. Both are fantastic watches
Man I hate it when I'm 15seconds late thanks to my watch 😤
Got my first watch 3 days ago from my great grandfather. A 7a38-7190 Seiko. Absolutely beautiful watch
I took the time to learn how to adjust most movements to 0 to +2. Not that hard. I just need a couple good tools and some patience.
My $100 seiko adds like 15-20 seconds a day. If I wanted an accurate watch I'd wear a quartz. I think automatics are really cool and I'm not a scuba diving astronaut so I don't need to keep time by the seconds. Every few days I'll set it back a few minutes. It's fine.
That's why I Look at my Phone, when I need to know the time

Mechanicals are for their beauty not accuracy. Btw COSC requires -4/ +6 sec/day. JLC, IWC, VC are not COSC certified but they achieve better accuracy. Someone was citing Casio: I fully aggree. But eventually one have the phone watch which is sync with the atomic watch. We want 'jewles' and that's why mechanical are made for.
what about timex? what movement it is using?
My pocket watch has a built in calculator, camera, satnav, wireless long range communication and sycs its time from aromic clocks in space.

Seriously though, we buy mechanical watch because we appreciate the engineering and craftsmanship that remind us how people in the past can make such wonderful machine. To achieve accuracy on mechanical watch in these days is like trying to set a goal or record. Not for everyday use. Some people are really simple minded to think we buy mechanical watch to tell accurate time. 😂

How does recalibration work on watches?
I used to own a Junghans Carbon solar. I left it on the window for 3-4 years and it had lost less than a single minute. I don’t know if they’re all that accurate but I still can’t really believe it.
And quartz watches are just geniuses out the womb ig
If your watch is fast you’re never late, I set all my clocks 10 mins ahead 😆 don’t wear a watch tho because I have the time on my phone, if phones weren’t a thing I’d wear one
I do my own watch repairs and I am able to get Seiko’s, orient and other cheap watches and regulate them to COSC standards the Seiko I am currently wearing gains 1.5 seconds a day.
Grand Seiko is not pure mechanical watch, it uses electronic control to regulate speed.
(Laughs in phone watch)
Me with my 200$ phone:look what they need to mimic a fraction of our power
My Bulova and Seiko run about 3-5 seconds fast which I don't mind. That means I'll be early wherever I go.
That’s the truth of it right there, how much of a watch nerd do you have to be to miss a couple seconds a day, I get that it eventually compounds but it would still probably take a week or two to notice
