Rating criteria designed 150 years ago really do need to be updated. This is why TV, Radio, Astronomy, etc., rely upon atomic clocks. Imagine watching a TV station that had 6 seconds of dead air between each change of programming. That would hardly be acceptable to anyone.
Making mechanical watches accurate really reached its zenith with various marine clocks and the invention of the tourbuillon. Not exactly new technology. I don't disagree that instruments used for purposes requiring both precise (explosives, astronomy, et al) and/ or accurate (broadcasting, public transport) timing should use quartz/ radio controlled/ atomic timepieces.
It is. It's a ProMaster dive watch. Accurate and just about bomb proof. I needed a watch that would work under extreme pressures and still give me accurate readings.
I confess myself not an expert in the Citizen line up. Does the ProMaster line have thermo-compensated movements?
My Breitling will work under extreme pressures (200 ATM) and is suitable for saturation diving. It's also guaranteed to accurate to +6/ -4, which is fine for me.
So if we want an accurate watch, all we need to do is find a well made quartz timepiece.
There are plenty of them made to withstand more abuse than a $20 Casio. Many people prefer to know what time it is, rather than roughly what time it is. Just ask your boss if you can leave the office everyday roughly two minutes early!
I can honestly say I've never had my Breitling be two minutes off of what I set it. Six seconds, maybe. Two minutes, no.
Oh, and you'd be surprised what abuse a $20 Casio can take, especially if it runs off an LCD module. I've seen people boil and freeze LCD modules to have them work fine.
Where I live, the trains do run on a precise schedule. You can set your watch to them. If you are 10 seconds late, you might not miss your train, (that's might not,) but you certainly won't get a seat for your commute! I wouldn't want to have to reset my watch every week just to be sure, because it is certain that if you are 30 seconds late, you will miss that train! The doors often stay open less than 20 seconds. If your watch is accurate here, you catch your train and you get a seat.
Rolex makes a watch that had a body milled out of a block of steel. That's pretty strong! On the other hand, I've never bent a watch body. But it's not accurate. It's only close. It doesn't make sense to me to pay for close. I don't need one that will glow brightly inside a cave so I didn't need tritium makers. Some people do.
I want a watch that tells me the correct time, and will do it all the time. There are plenty of good quality watches on the market these days that can be had without paying for extras. For my money, Citizen makes them.
Where do you live? I can honestly say that, in my public transport experience in London, D.C., Switzerland, and New York, I have never seen a train that was. A. On time. and B. Running to the point where +6/ -4 (on average) would cause you to miss it.
You obviously value extreme accuracy. I value piece of mind, which automatic/ mechanical watches offer. I don't have to worry about batteries. Eco-Drive, to some extent, alleviates this, but I still don't trust it. Also, I have a mechanical heart valve which ticks and drives me crazy, so I try to avoid all other sources of ticking. Hence, mechanical.
Oh, and to the OP: You might also want to look into Vostok Amphibias. AK-47 of the watch world- not too accurate or refined, but you can dip it in mud and fling it against cliff faces and it will still work.
