I saw the video as well. It seemed to me that he was whining. Special movement - special care needed. You don't take your Ferrari to Jiffy Lube for an oil change. I wouldn't trust just any watchmaker under the hood of that watch, the Longines Ultra-Chron, or one of the new ultra-accurate Citizen models. Best left up to the folks that understand the movements.

Very impressive performance and I actually like the look, I think racing inspired chronos can be a bit loud and still look good. Unfortunately for me I'll never own one because of the price.  

Unique and very cool.

From my research Citizen seems to make the most accurate quartz watch at this time, and the specs are impressive indeed. The Citizen AQ6110-10L released in 2022 with the caliber 0100 claims ± 1s/y.  Some of the other high spec quartz watches with fall in as show below. Other specs are shown for comparison purposes. Anything better than 1ppm (1E-06) is remarkable from an instrumentation point of view. To achieve these levels of accuracy the oscillator needs to be temperature controlled. This is referred to as a TCXO (temperature controlled crystal oscillator). These oscillators were once relegated to professional frequency counters or signal generators due to their size. When I was working with frequency counters about 15 years ago, the smallest TCXOs were about 20x20x40mm. They have shrunk along with other components to fit into GPS units, smart phones, etc. Apparently now they are small enough to fit into watches. The smallest TCXO I could find measures 2.1x1.3x1.1mm. These have been commercially available since late 2020. I wouldn't be surprised if we see more ultra spec quartz watches in the future. (I included the Longines Ultra-Chron mechanical in the list because it is my Grail watch.)

Citizen AQ6110-10L Quartz: ± 1 s/y (<0.04E-06)

Citizen AQ4091-56M Quartz: ± 5 s/y (<0.2E-06)

Typical Quartz Spec: ± 1 s/d (<12E-06)

Typical Quartz Observed:  ± 1 s/d (<6E-06)

Bulova UHF Precisionist Quartz: ± 10 s/y (<0.3E-06)

Longines VHP Quartz: ± 5 s/y (<0.2E-06)

COSC Certified Quartz: ± 0.02 s/d (<0.2E-06)

Longines Ultra-Chron 2022 Mechanical: ± 1 s/d (<12E-06)

You have very nice watches. I would suggest the upper limit is established by your situation. You obviously need to have the ability to pay for them, not cause family strife, etc., and not cause yourself stress by feeling like you have too many watches. If you have the ability to give them wrist time, I don't think you have too many. That is to say, if you are enjoying them all then they were worth the money you spent on them. If you are no longer enjoying them, or their presence is causing stress then its time to let one or more go.

Good choice. The surrounding prime numbers are 3391 and 3413, and those just won't do.

You have an excellent point. This is why we have a community. It is spectacularly accurate. Very impressive in fact. It may not be legible on my wrist but it is perfectly legible indoors and at 45mm it's perfectly readable when propped on its bracelet alongside my computer monitor. Now I have an Invicta desk clock!

Invicta actually does have a diver I like, the Automatic Pro Diver in black, 44mm (31485), $69.90 on the website with an NH35A movement. Not a bad deal at all.
