The Citizen is nice... But learn from my mistake... MAKE SURE YOU REALLY LIKE IT, because you and I are willing to pay for one of those but most people won't lol. Sold mine for about half of what I paid... Even it was hard to sell lol.
The A060 isn't as accurate as Citizen claims, that's something you should be aware. Mine was running at roughly +8s/year, there's also some watchuseek threads on the subject and even the JOMW YouTuber admitted his was also slightly out of spec lol.
The Longines on the other hand, it's an automatic watch from a well respected higher-end watch manufacturer, definitely easier to resell if you want to move to something else.
I have a 1968 Ultra-Chron, cuzz I wanted a 36000vph that didn't break the bank. I had it serviced and runs between COSC numbers, can't complain!
