Quartz watch regulation – Very geeky

rcs914 · Apr 6, 2017

I used to hang out in the HAQ (High Accuracy Quartz) forum over on WUS and I don't ever recall this specific model being discussed as being a HAQ - good to see that there are others out there. I only have a Pulsar PSR-10 myself, which is non-thermocompensated, but has a 196Khz crystal. It was supposed to be good for 10/s a year but that's no longer the case with these.

As suggested by others, I evaluated Polaris by wearing the watch for a month on a mostly daily basis (my other watches were jealous of the extra attention the Polaris was getting). Beforehand I adjusted the watch to match the NIST site to a fraction of a second. Here's a video I took this morning. Not bad!

Can we have a wrist shot please?😀
I didn't know that GG had designed these watches for Omega. Thanks for sharing.

Here's a cool article on the watch. It's in French but worth the read. Not only did Gerard Genta designed it, it was promoted by none other than John McEnroe. A similar Polaris was regularly worn by Swatch Big Cheese Nicolas Hayek.

Brilliant post, @Deafboy . Much enjoyed, thank you. And I think the watch looks very cool. Am I right in thinking that the Titane is larger than previous models of the Polaris which all seem to have been around 32mm? Your Titane looks a more 'mdern/wearable" size. That is gold inlaid into Titanium, right? Very distinctive, and not something I have seen on any other watch case. A lot to like here!

Actually mine is of that size and fits well on my smallish wrist. The chronograph version of the Polaris is much bigger (38-41 mm?). The Multi-Function (shown below the chronographs) is probably in between. Maybe @tyrantlizardrex can chime in...

Is the multi function the same movement as the x33? Well I assume slightly edited like the new yachting Speedmaster.

The multi-function had a cal. 1665 (ETA 988.432). The case is said to be 37.4 mm.
I don't know about the x33.

Update 2021: Long term performance

I've been taking measurements on occasional basis of my Polaris since I changed the battery in September 2019. The way I now do this is to take a video of the movement of the seconds hand use an iPhone with an app that overlays a precision timestamp. Here's a graph of the results. So over a period of 526 days the watch accumulated an error a smidgen over 4 seconds. This corresponds to 6.9 ms/day or 2.5 seconds/year.

Geeky, and amazing timekeeping. Your Polaris beats the pants of a Constellation Marine Chronometer operating perfectly within specs.

That's true, which shows that there was significant improvement in technology between the Marine Chronometer, which was probably the best of its day, circa 1974, and this Polaris (1988).

Very interesting. Compare your result to Citizens new 0100 watch claiming 1 sec per annum due to some pretty exotic crystal temperature compensation technology.

Fascinating post - thank you.

When it gets down to accuracy to with 1s per yr don’t you think we need to ask ourselves what is more accurate: the watch or the universe?
