Recently a tread in the general forum regarding Swiss vs Non Swiss quartz sparked off an interest to me - Japanese quartz watch!
Can any of you suggest budget priced Seiko or Citizen quartz watch with accuracy like the Pulsar PSR 10 (+10 sec/year)? I couldnt find Pulsar watches anymore and Grand Seiko or even the Citizen Exceed is currently out of my budget. Thanks.

I will let our quartz watch expert Tiggercat answer this one, since I do not collect nor have any interest in quartz watches at this time. (Read my Signature ;D). I do doubt, however, that you will get such accuracy as that Pulsar in todays market without spending close to or over $1,000. The low priced Seikos will deliver more like +/-10sec./month or worse. A mid-priced Seiko (~$400 to $600) may deliver +/- 18 to 20 sec./year. The Tigger will know for sure!  |

I've had great luck with the accuracy of my Catoura. Great designs too. The bracelet is a tad uncomfortable at the clasp but that could just be me.

How about one of those Casio Wave Ceptors. The Atomic clock sync means accurate to within 1 second per million years or something. From waht I've seen on the web, someof them are quite good looking timepieces.
I believe Citizen also make one of these.

;D 10 second per year accuracy is generally found only in temperature compensated movements and watches with those movements start at 1000.00. You might look to the bay for a used Longines Conquest VHP. those often go for around 300.00. However to get that accuracy in any brand you MUST wear the watch consistantly and for at least 12 hours daily. These watches are for purists who appreciate their quality. As pointed out if you want only accuracy a cheap 30.00 radio controlled watch which resets itself twice daily will blow them out of the box.

 to Knight Watchman: In theory you are correct and I cant explain why they have to be worn however if you research the literature from Longines or Seiko you will see that is what they state. My three Krieger Marine Chronometers maintain the same tolerance regardless of being worn. But my two Puslar PSR-10's and four Longines VHP's only meet their specs if I wear them. My rolex oysterquartz seems more dependant on battery condition and how long since the movement was last serviced than anything else but then again its compensation is analog not digital as all the others are. My four Seiko Perpetual Calendars all need to be worn to keep their 20 second per year marks but the instruction manuals for them specifically state that fact. And of course the Seiko Perpetuals are not temp compensated but rather depend on their high (186,000) frequency for their better accuracy. I've collected and researched these models for years and even with having repaired watches for over 30 years I still cant explain all things---just know they happen. I've got all the technical manuals for the Longines(for all four progressive models) and while they state they have to be worn no explanation as to why is given.

The general consensus is correct, if I recall - they don't make anything like the PSR any more. I'll dig through my memory banks and see if I can come up with anything else.
The Casio is a good choice, but let's get one thing straight - Wave-Ceptor watches are NOT exceptionally accurate because of the movement. They are standard quartz watches that have the luxury of being automatically synchronized using the time signal. There IS a difference - if you take away the time signal, you have nothing more than a standard quartz watch.

Unless you are in an area that easily gets the signal you have a quartz watch with normal quartz accuracy. Before I moved 4 years ago it was like pulling teeth to get a signal through to my Casio. Now that I have bought a house a mere 10 miles away I get a signal nearly every night on both my Casio and Junghans. Location is everything!! |

The Atomic clock in Colorado is supposed to be available throughout the continental US. I live on the east coast of Florida and have no trouble getting this signal to sinc my tough solar Casio. I do, however need to keep it out near a window. When in my dresser with the doors closed, it will miss the time sync about 1/2 the time. |

I stumbled across some affordable high accuracy quartz in the last couple of days. Apparently they are Japan only models; 1) Seiko Perpetual Calendar Quartz SBQK079 2) Seiko Perpetual Calendar Quartz SBQK081 3) Seiko Perpetual Calendar Quartz Diver 200M SBCM023 All three uses the 8F32 cal which claims +20s/year accuracy. All priced around US$200+. I think I have one package coming soon. |

 One of the ways to increase accuracy with quartz movement is to boost the frequency from the 32hz standard. Seiko took the frequency up to 186Hz for the perpetual calendar models and that change accounts for the increased accuracy.

Thx ltgary, appreciate your postings. Regarding boosting the frequency from 32Hz for better accuracy; is this something we could do on our own or only a watchmaker could do that.

Bullosa: Sorry neither you nor your watchmaker can modify. Only way is for a manufacturer in the initial design of the watch.

i always thought quartzes were real accurate a quartz would be more accurate than a kenetic right. but would a ecodrive be more accurate than a regular quartz since there would not be a continuingly decreasing battery strength? most likely better if the watch doesn't have any chrono complications to draw extra power from the solar charging cell then the ecodrive atomic would be the most accurate maybe......
