Accutron

[luddite]

This was my first Bulova Accutron, after the first five years when it was my daily wearer it just stopped and no local jeweler would touch it.
I heard about SilverHawk and posted it to him, now it's back to its former glory...

Let's see those hummers.

I've had a number of 'Hummers', but my Accutron Deep Sea 666 is the only one that remains

My spaceview says hello



Arrived yesterday and loving it

Lovely watch. I've owned a few and still have this one:

I have had a few.

I picked up a 1969 Accutron a few weeks ago. You wouldn't know it from my dreadful picture but its in amazingly good condition and extremely accurate, even more so than my speedsonic which is also accutron powered.

From my perspective quality is on a par with a Longines or Omega of the same era, surprising then that given the amazing technology they are not more highly regarded.

This one is my favourite . Always been looking at these but never pulled the trigger yet

Love the deep sea but that spaceview is superb!

Lovely watch. I've owned a few and still have this one:

I see both the others have faded to yellow as mine has - I didn't realise the originals were actually Orange for years!

Interesting that yours has a countdown bezel.

Had this one, but sadly it failed. Sent it to Keitht but the part it needed was difficult to come by so it ended up keeping some others going.

I have had a few.

Still find it odd looking at a watch with no crown.

That's no Hummer! (Is it?)

[Padders]

M

No but it is an Accutron, it says so on the dial!

Accutron II - it makes a very similar (if quieter) noise to my Omega f300, with a second hand as smooth as butter.

[HenPecked]

No but it is an Accutron, it says so on the dial!

It's on the crystal, actually.

I had to get the nice lady to open 4 watches that they had in stock before I found one where the glass had been put in straight. One was about 5 degrees off - how that passed quality control I have no idea.

[snowman]

I thought you'd say that

I had one of the Accutron II Deep Sea 666 homages for a while (As I killed my original, but then got it fixed and decided I didn't need them both).

I've now got a Bulova Moonwatch with a similar movement, but I don't think that's called an Accutron (?)

They're fine watches for the money and the sweeping quartz hand is a nice feature.

Don't they use their high frequency Quartz movement; 127khz (or thereabouts) as opposed to 32khz in a standard Quartz?

Says 262 on my moon watch.

Go stand in the corner, this thread is about HUMMERS!

[Dave+63]

Says 262 on my moon watch.

I didn't realise it was quite that high!

Stolen from a post on another Watch Forum (via a Google search)

"According to t'internet (www.howstuffworks.com): The Precisionist uses a pair of tech tricks to overcome the quartz mechanism's weak points. First, its crystal is unique: most quartz watches use crystals shaped into two-pronged tuning forks, but the Precisionist literally goes one better with a three-pronged fork that the company claims can oscillate at 262.144 kilohertz (or 16 beats per second), about eight times faster than the 32.768 kilohertz (about 1 to 2 beats per second) that is the typical frequency for quartz oscillators."

I have (and had) no doubt that your figures were correct Snowman; I knew about the three pronged crystal too.

I don't know where the author of that piece got their information from though because 262khz is 262,000 vibrations per second, not 16!

I think it means the second hand moves that often, not the oscillation.

I shared it, because I wasn't sure how the UHF differed (three pronged quartz is rather cool, surprised they didn't make more of that!) - That relates to Precisionist movements, which I read somewhere are slightly different to the UHF one in the cheaper watches, but they share a frequency.

Here's mine from 1978 :

Lovely! Do you have a model no./name for this one?

Well it has the serial number on the back plus the year code which shows M9 for 1969 and its an Accutron Calendar:

Though I don't know the exact model number, there are a few similar watches on mybulova pages.
