I want a High Accuracy Quartz watch. Please help.

This is my Certina Chronometer grade GMT quartz. It is running +1 second/33 days. Not a Longines, but still decent quality. And it was 258$ with a good discount.

I hear good things about Grand Seiko…

Sinn UX has thermo compensated fully serviceable quartz that’s rated to 10s a year and battery life of 7 years

It’s only 13mm thick and is rated to 5000m

Bonus can be used as a hammer it’s so tough 😂

Grand Seiko Quartz are insanely accurate by the sound of it.

Can't speak for their accuracy, but I'm drawn to Bulova quartz watches at the moment.

A Casio with Waveceptor, always synchronised with atomic clock

One of my favorite

Bulova Jet Star! Check it out.

I did, but want to know if I should completely not consider this Longines, esp the GMT model. The Jet Star is not a GMT - I want to know how useful GMT will be for the travel frequency I mentioned. I feel like the V.H.P GMT offers more for the $$ .

Is there any specific reason you did not go for the GMT version?

From affordable to spenny: Bulova, Certina, Longines, Grand Seiko, these all have great high accuracy quartz options.

Oh, sorry. I should have read your post more carefully.

Certina DS Action Chronometer Quarts

Often found on sale, wearble dimensions and high accuracy.

I don't like GMT. Prefer to stay simple.

The Precisionist and lunar pilot are +/- 10 seconds a year

I don't really know too many quartz GMT watches off the top of my head so I'll answer the usefulness question. Honestly, it depends on how you travel and your day to day life. If you pick up a traveller's GMT movement and tend to have layovers on multiple timezones or just like to travel to multiple areas on your trips, the isolated local hour hand is absolutely fantastic as it makes switching super easy. On the other hand, a callers GMT is a bit more annoying to use for traveling yourself as the changing the local hour hand hacks the movement but it does allow you to easily contact family or business contacts on other timezones. You'll need to figure out which use case fits you more. Happy hunting man.

Hi Timessstamp, you mentioned that you couldn’t make up you’re mind between the GMT or 3 hands and travelled overseas 2-3 times per year. So if you can change the time by only moving the hour hand then you can easily change the time for most time zones when travelling.

Look no further than an SBGN003 or 005.

A True-GMT, to boot.

This thing is 1s behind after 6 months of runtime.

Without time synchronization I know of two, that can do this magic, though there are probably more:

Citizen Caliber 0100 watches and

Grand Seiko Caliber 9F watches.

Otherwise you need a watch that can either calibrate by atomic time signal or by connecting to your phone.

I own neither of these but I am fascinated. So, the Grand Seiko is Grand Seikoish made with incredible precision and love to every detail. Moreover it is possible to adjust the movement and calibrate it to your environment. With Citizen you get the option of an eco-drive. For me, that would be more valuable than microscopic polished hands 🤷🏻‍♂️.

I am, however, not sure that a Citizen 0100 is behind Grand Seiko, not even in regard to the quality of the making. It sports an 8 MHz quartz, self calibrates to environmental conditions, costs about three times of a Grand Seiko 9F and is absolutely rare. It is more like a demonstrator watch in the kind of "F* you all! Yes, Rolex, I'm looking at you. Try to keep on par with our abilities 😉." It is probably easier to go the small step up to Grand Seiko.

Okay, thank you. The 3 handed allows that functionality.

Is it a 9F movement ?

The longines watches I have mentioned in this post also have +/- 5 secs tolerance. Yes all the three brands are incredible.

Yes. A 9F86, because of the GMT caliber.

Again, a True-GMT with an independently moving hour hand. Fantastic through and through.

The new 40mm Tissot Seastar 1000 might interest you. It is thermally compensated, a HAQ and has a few other cool features.

Avoiding rotating bezels for a while.

Can’t beat a thermo compensated quartz from Brietling. My quart Colt is outstanding (when the battery has charge).

My second choice is probably percussionist movements by Bulova.

Grand Seiko!

It really depends on what you mean by #haq. True HAQ as enthusiasts term it usually means ±10s / year independently, with no external signal like atomic clock radio, cell tower, or GPS.

In order of price I have owned/own

• F91W with the Sensor Watch M0 module, running the nanosec thermocompensation watchface code

• Tissot Seastar 1000 with the PreciDrive movement

• Longines VHP 36mm

• GS SBGX261

They are all fantastic choices depending on your budget, though the top option is more work (can be fun though)

So interested to know about the Casio. Is the module OEM or aftermarket ? Wow you have a great set!

Update:

Thank you all for the numerous options presented! I didn't expect such eagerness from the community when I posted this first!

I shortlisted two watches. One, obviously the Longines V.H.P Gmt (+/- 5s a year) and the other a Citizen CC3000-89L GPS (+/-1s over 100,000 years). I did not include Seiko Astron models as they were$1000 more than the Citizen.

After much analysis, I pulled the trigger on the Longines. Rather than saying what made me buy it, I'd like to share what made me drift away from the Citizen which is miles ahead of its time and in terms of technology. I was so close to buy it.

1. Size: 43+ mm case. I don't want a frying pan on my wrist. I had a timex ecpedition in 43 but due to it's tight lugs, it was just about a good fit, but the dial was huge.

2. Claims of accuracy and regular sync with satellites: I compared the Citizen with a Seiko Astron GPS. There was a 1-2s difference between them when they sync with Satellites, tried multiple. The Citizen was faster to sync. I'd rather go for the a Citizen 001 movement but it was costlier and did not have GMT.

3. Feature overkill: In order to change the timezone, one needs to rotate the seconds hand through the timezones mentioned in the bezel on the Citizen. I really do not need so many options and so it was an overkill for me. Seeing this watch first hand helped me find the answer to the question I posted as part of this post.

4. Brand: I relate Citizen with a future focused tech first brand. I wanted to have something from a premium legacy brand and so Longines made the cut. It is also a nice upgrade from the Tissot watches I have.

5. Support network: Surprisingly Longines and Seiko have amazing showroom and service network in my region than Citizen. For a battery change, the Longines can be handled at home as I have the tools and the battery is easily available.

Can't wait to get my hands on the watch (I got it from a different country for a good deal, so waiting for it to arrive). This will be my first high accuracy quartz watch. Onwards and upwards 🎯

I got the Longines VHP GMT, finally! Worth every penny!
