    Seiko Sportura, most accurate Quartz!

    Check this out. Old knackered and the most accurate wuartz I've ever owned. I've had Aerospace, B1, Airwolf, X33, Tag , Aquaracer Chronotimer, Normal Seikos, Normal Tags etc and this just destroys all of them! Mental.




    (It's the Sportura World Timer).

    Official spec on Cal H023 is 15 sec per month.

    Either you got lucky, or they sneaked a thermocompensated movement in without telling anyone!

    Remember that sometimes your wearing pattern and movement produce a superior result.

    Seiko Sportura, most accurate Quartz!

    Over a year and a half its been through pretty much everything, sitting still, playing squash, normal wear, swimming. I think it's a fair representation to be honest. I haven't babied it, (as you can see).

    Bang for the Buck.

    Actually, I don't think you got lucky. I also had a Sportura years ago that looked similar to yours. It was incredibly accurate. When I sold it, I even made a specific point to discuss its uncanny accuracy. You can read my For Sale post here. The watch itself looked like this:

    The best quartz watch is the Walmart special.
    Better than an atomic clock!


    It has outperformed everything else in extensive testing

    And there is the Pulsar PSR 10 that delivers 10 seconds per year. Not nearly as good looking as a similarly performing Chronomaster but the price was right.

    How do you manage to keep the finish looking so good on those?
