    Bulova 262 kHz

    Hi, I'm just aquire the Bulova Moonwatch with 262 kHz movement. I don't know much about quartz watches. I guess this one fits into this forum. It is beautiful watch.
    Cheers.

    I think that is the 2nd generation version. This one is the first generation with the date at 4 o'clock. For the first gen, there is a bracelet version and one that comes on a sort of carbon fiber looking leather band with a NATO'ish 2 piece strap as a secondary. Here this is the NATO like velcro 2 piece strap. I like it much better than the leather. Nice watch. Mine has always been very accurate. I've heard one reviewer claim it's thermo compensated by design but I'm not sure if that is true. My wrist is about 6.75".

    Right, mine is the second gen. I thought about getting the SS version then this one came up at good price in my area so I grab it. I really like the black case though.

    I also like the Bulova font on this one because it looks like the original.

    It's not Thermo compensating. (Not that I know what's it mean.) See the Bulova adds here.

    It's say: “Most quartz watches are accurate to 15 seconds a month – Bulova Precisionist is accurate to 10 seconds a year.
    The key is Precisionist’s unique three-prong quartz crystal, which produces a vibration frequency of 262.144 kilohertz (kHz), eight times greater than the usual two-prong crystal and the highest of any watch available today. And, the innovative design of the Precisionist movement reduces the effects of temperature variation without using a high maintenance thermo-regulating integrated circuit.
    The result is a watch that is extraordinarily precise, yet so easy to operate.”

    Opinion is divided. I have one, I must admit. In fact, I have had a couple. Mine have never met spec and I tend not to count them when I think of my HAQs. They are, however, designed to be more accurate than standard, 32 kHz quartz watches and despite their lack of thermocompensation and reliable 10 SPY performance, a fair number of people, here, do consider these watches to be HAQ. Try searching the forum; you will find a lot of threads about Bulova's 262 kHz offerings.

    The 2017 Bulova Grammy silicone strap 47mm model is going for $170 on Amazon. It's a 262 kHz Precisonist, but I noticed it gained a second since I set it 3 weeks ago, so I guess we are not talking 10 spy territory. I always wonder if the factory can adjust that or is it pretty much fixed?

    The less expensive Bulova Precisionist - 96B257 is holding to the second in about that period. A bargain and my first HAQ.

    I think you hit the nail on the head here. If you look here, you essentially see the same thing:
    https://calibercorner.com/bulova-caliber-p102/

    Now all they are claiming is that by increasing the frequency, there is less opportunity to be affected by temperature, so it's less sensitive to temperature in a passive (not active) way. In effect, they are claiming to reduce the thermo sensitivity in a different way than other movements do (perhaps not as effectively, I don't know). Frankly unless you live in Antarctica or Death Valley, I wonder how much it matters. My own watches are either on my wrist (honestly not very much as I have too many watches) or sitting in my winder at 67-70 degrees year round. Obviously if I'm wearing it, it is probably 97.6 degrees (yes I'm cold). And then does the frequency of 262Khz really reduce this already slight timing difference? I'll leave that to the specialists.

    I guess it's still better than my Dad's Accutron from 1968.

    Higher frequency in the tuning fork model but not as accurate. I find the original way more interesting though.

    This particular one is inscribed by my Mom for my Dad and was given to him because he was a B-52 Navigator in the Air Force (and thus an accurate watch was very useful). I got it in pieces from my Dad's estate. Glad it works again. Love that HUMMMMMMMM..... that the old Accutrons had.
