That’s why I eventually settled with gshock that has solar charging and syncs time twice a day with radio towers (or bluetooth if you are somewhere in the world where there is no time radio signal)
Even rolex needs time setting, servicing to lube and clean metal parts, etc.
Gshock on the other hand will work for 10-15 years without a single manual time adjustment or battery swap needed.
Absolute unit.
This gold metal square one I especially love for summer:

So you can understand why the https://en.wikipedia.org/wiki/Quartz_crisis had Swiss watchmakers fearing for their industry. Mechanical watches couldn't hope to compete with electronics on accuracy. Hence their pivot to understanding that watches are jewellery. Fancy, complicated jewellery with moving parts, but jewellery, and priced based on style and cachet, rather than on function.
In Japan they sell the Waveceptor brand Casio watches. I got a nice simple titanium (case back and strap) with solar, LCD alarms and radio control for around $200. It even auto re-centers the hands if they are exposed to strong magnets. You can also get these on eBay and Amazon though 3rd sellers.
Those are not as good as they seem to be. I once had a g-shock mudmaster, seemingly an absolutely overbuilt thing, and it was resetting randomly in wet conditions. Maybe that could be fixed on warranty and it would work next 50 years flawlessly, but it didn’t inspire any confidence in that brand. They re-positioned themselves as a loud fashion brand, not a tool watch manufacturer.
I can’t say nothing about gshocks that have moving parts (actual hands) and what have you
Gshock metal square (like the photo I referenced) never failed on me (and I have 3 of those in different colors: gold and silver lcd ones, and black memory in pixel new one)
bluetooth on watch sounds disturbing
You absolutely can skip setting this up
Though even if you consider any possible harmfull effects like thyroid nodules formation correlation [1] (people somehow only think about ionizing radiation, but there much more that happens in a cell that can be possibly disrupted without xray level stuff to damage dna or heat: there are ion channels and what have you), the Bluetooth on gshock — if set up — will work only for a few seconds twice a day. Basically nothing even if you sleep directly on it all night long

I'm fairly certain they were concerned about privacy, not... any of that. Bluetooth is promiscuous in an already noisy band.
