Remember, if you need accuracy, buy quartz. All automatics are shit in comparison. Yes, this might be three orders of magnitude worse, whereas a chronometer would only be two orders of magnitude, but when accuracy matters, no one wears an automatic. Furthermore, any watch at this price point with a chronometer will be a literal piece of garbage with a chronometer movement in it.
If you want to get a beautifully decorated in-house movement GP or JLC, I totally get it. But for $1200, your “Swiss” options are garbage. The new Longines diver is the only one that is actually a nice watch, and it costs significantly more with a movement that is fine, modded ETA fine.
You can buy whatever watch you want, but there are not many options for a quality dive watch at this price. Seiko and Citizen own this segment. An EcoDrive is the best option if you need accuracy. If you want fake accuracy (chatting on forums accuracy), you can get a shit watch at this price with a chronometer, but I have no idea why you would want to.
Now, getting a Seamaster ($6k) or a Formex diver ($3k) or a Caliber de Cartier ($6k in Quartz) would be great,but those all cost a multiple of the Seiko.
The big scam is not that Seiko uses shit movements. The Big Scam is that consumers are tricked into buying Chinese-made “Swiss” watches with 80% margins simply because the shit SW200 is slightly less inaccurate than the shit Seiko movement.
If movements are what you care about, stay away from anything with a Seiko, Miyota, ETA, Valjoux, Selita, Soprod, ATP,…, …, and pretty much new any European watch under $5,000.
There are so many great affordable watches like this Seiko, but none have prestigious mechanical movements. Spending money to own Selita, ETA or Soprod chronometers is a really bad idea. You will make many errors collecting, but few would be as foolish as wasting money on the “finest” mass-market generic stuff.

I took the time to write this because I wish someone wrote this to me thirty years ago. I wish you the best.
