I noticed Ron has put on the table that HAQ is now "less than or equal to 10 s/yr based on performance not specifications." Has some interesting implications if that's the new norm.
Based on performance, sorry all you Certina, Tissot, and Chris Ward owners. Even though those Precidrive watches are specd at 10 s/yr, most of them aren't meeting those specs. A quick look at the posts show the DS Action Divers, the DS-8's, and a bunch of the current batch of DS2's aren't making the grade. You'll be missed.
Bulova based on performance is actually performing better than a lot of the Certina's, but again not routinely at 10 s/yr, at least you have the Bulova forum.
Morgenwerk, sorry no performance data for a complete year ever. Maybe if 2 or 3 people post some data you'll be welcomed back.
Apple watch sure you're thermocompensated, and specd to be the most accurate watch in the world. No one is going to leave you not connected for a year, you're out of here.
Now of course there is COSC, an independent verification that the watch is probably 10 times more accurate than a normal watch, apparently is not good enough.
That leaves us with a few models from Citizen, Seiko, Longines, and Breitling(as long as they keep making quartz). Perhaps a few vintage models from Omega and others if they are still meeting that spec.
Now I believe some folks have speculated that it be based on the technology the watch has. So if its feasible than it's in? Seems awfully random, and a leap of faith as opposed to you know the reality of specifications. Who makes that call?
Personnally I would prefer if this was Highly Advanced Quartz forum. Lot of cutting edge stuff happening in the GPS and Bluetooth area along with the traditional High accuracy quartz, and leave it at COSC based on specs.
