Hi
I came across this watch and wondered what we know of it -okay it is quartz but seems to offer 10sec/annum accuracy?

The precisionist is an interesting movement. Instead of running at 32hz they run at 256hz (rough numbers) which increases accuracy. Also the second hand moves in 16 steps per second (a normal 28800 vph auto runs at 4 iirc) so it has the smoothest second hand this side of a spring drive.
Cases and styling can be challenging but there are some nice ones if you look hard enough.
Oh biggest downside other than some of the designs is that they eat batteries.

Have a Bulova with the precisionist movement, and it's accurate almost to the point of being annoying! The second hand is something else though, great to see.Originally Posted by Low-Key
Started out with nothing. Still have most of it left.
I have a Lunar with the Precisionist and the accuracy is truly insane. Battery life is 2 years, which I find acceptable. It never needs to be adjusted between battery changes.
My Bulova Precisionist is superb.
Bulova Precisionist styling varies hugely across the range, but some are very handsome.
^ this. The Precisionist second hand is something special. It’s wonderfully mesmerising
Hi
Thank you all for your thoughts/replies.
Julian 2002 - some designs eat batteries - given a divers piece so a practical watch, how much we looking at for a battery change/reseal/re-test every 2 years?

Yeah roughly 2 years or a bit under for mine.

Is the watch movement particularly large, I read somewhere that the watches are on the large size due to the size of the movement.

Bulova’s website shows watches in the Precisionist range start at 42mm diameter (9.3mm thickness) and upwards in size. There are many larger watches in the range, but I don’t know the size of the movement.
Don't take this as gospel but I seem to recall someone either here or on WUS showing a picture of the their Precisionist movement: It was tiny!
I was reminded of my rufty-looking Traser diver. It looks all macho until you open it up and find it's got a tiny little Ronda 715 inside. ;-)
I might have the wrong watch movement in mind, a while back I was interested in the Bulova 'Moon watch chronograph' but decided that it's too big, I recall someone saying that Bulova couldn't make it smaller due to the size of the movement, so perhaps I'm getting them mixed up.

I have this en route.
It is large, thick, fugly with carbon dial, red accents, gold plating, knobs and crap all over it.. on top of polished PVD. And rubber strap.
But..
It has genial double function button at 8.
And gliding hand.
We shall see how it will be.

You could perfectly well be right. My memory of the movement being small is vague.

Ah no, I remembered correctly.
Here is the thread on WUS that I was thinking of: https://forums.watchuseek.com/f21/in...t-2570858.html
From https://forums.watchuseek.com/f21/in...l#post22284874 on WUS by Tom-HK:
Follow the link to WUS to see a strip down of the movement.One of the things I had heard was that the watches needed to be big because of the size of the battery. This clearly isn't the case, as the movement is surrounded by seas of plastic. In very tiny lettering, the word 'Japan' is included on this outer part of the movement.

Just a point of information, the crystal oscillators in these run at 262khz as opposed to 32khz.
Thank you for posting . It's the first time I have seen the movement , very interesting .
Yes sorry, being a programmer 256k = 2^18 = 262,144 and my brain slipped into old habits. You are indeed correct.
I had to look at it twice. I used to work at Marconi's in the 70s on digital test equipment and frequency counters.

Thanks, that's somewhat different.
