where'd you find it? I was looking earlier today and could find nothing on this lump except one front picture. I'd like to know what model it is etcetera.

 

Hi!
I have an older Bulova caliber 242 quartz with the same style button at 4 o'clock. On the cal242 this button is called an "Accuset Corrector".
Quite complicated little thing. It does look very interesting when activated. The second hand either slows down or speeds up in order to "catch" the standard time seconds.
My best guess is that the button does something similar?




From the technical manual:
“Using the ACCUSET Corrector“
After a period of time, if the watch is no longer accurate to the exact second, press and release thevACCUSET button the instant the time stenderd used naches the 60th second (12 o'clock) marker. (Maxi-um correction is + or - 30 seconds.).
The sweep second hand of the watch will temporarily stop if it is fast, or accelerate if it is slow until it is in synchro-nization with the time standard..
In order for this to work correctly the system must be set correctly by the watchmaker after a battery swap. as follwos:

How to calibrate after battery swap:
Setting Instructions
Step 1. When sweep second hand of the watch
reaches the 60th second mark (12 o'clock marker),
pull crown out to Position 3 (See Fig. 5,).(Allhands
will now stop.)
Step 2. Press and release ACCUSET button.
(ACCUSET circuit is now synchronized with position
of second hand.)
Step 3. Turn hands forward until date changes. (This
establishes midnight.) .
Step 4. If A.M., advance hands 5 minutes ahead of a
time standard being used. Then gently turn the
minute hand back to correct time.
If P.M., advance the hands past 12 o'clock (noon)
to 5 minutes ahead of time standard and then gently
turn the minute hand back to correct time.
Step 5. When time standard being used reaches the
60th second mark (12 o'clock marker), push crown to
the "intermediate" position (Position 2). All hands
will start instantly.
Step 6. First set the date, then the day. Crown must
remain in Po'sition 2. Slowly turn crown forward to
correct date; backward to correct day. Push crown
"in" (Position 1).
Note: Day Indicator is printed in English and
Spanish, or English and French. Set accordingly.
Calendar cannot be set manually between 9:00
P.M. and 1:00 A.M. However, the mechanism will not
be damaged if crown is accidentally turned during
this period of time.
Additional Setting Information
Once the ACCUSET circuit has been set (Refer to
Step 1 and Step 2), there is no need to reset it,
unless the power cell has been removed, or there
has been an interruption of current.

 

A new project incoming. (Sellers picture).
Omega Automatic cal 342 "Fab Suisse". Ref 2531-2. Anyone seen this ref before? OVD sure does not list it...
On its ´s way to the spa very soon.... Exited to see how it will clean up!

 

OH MY GOODNESS.....

.....and that Kiddies, is why I wear a mechanical watch with three hands, drive a car with a standard transmission and why most of my bikes have had points ignition and kick start!!! JUST WHAT IS THE POINT!

how about this:
From the instruction manual:

Keeping your Omega Constellation accurate:

wear it.



thanks for your help Northernman!

 

You should remember that the difference in accuracy gained a quantum leap when these hi grade quartz movements arrived. They were precise at a rate pr month as you earlier would have accepted pr day.
I do love my vintage Connies and others, but ignoring the technological developments that occurred in the late 60´s and early 70´s will not be wise if one like to see the full picture.
Actually the Omega caliber 1310 MegaQuartz had a way more complex adjustment method, including being able to adjust only the hour hand, without influencing the seconds our minutes hands, when travelling between time zones.

 

Don't get me wrong, my home life is full of old mechanical junk. I think its a reaction to my professional life. Thats been full of measuring systems that can work in the 0.000001" range, new designs in weird electronics and or bearings and all sorts of other crazy high tech crap. I love quartz. Anybody who says it isn't better than mechanical in a lot of ways is living with their head in the sand.

But when it cost $200 to get the battery changed because the perpetual calender needs to be re-initiated, that's a bit much.

 

It only cost USD200 if you do not learn to do it yourself!

 

Could be the seller misread the ref so that 2531 should read 2581. Still not many with Fab Suisse on the dial. French export??
Love to hear some advice!

Picture of the dirty 342:

 

Damn right! I got the manual off the web and took care of it without the manufacturers help.

 

I wasn't going to, but then there's all the enabling here...

First non-Omega vintage watch

 

Undervalued and simply lovely.
Congrats!

 

+1 wouldn't mind one myself!

 

I just ordered a Stowa Marine Original, can't wait to see it on my wrist.

 

Mailman earned her money today

 

Barn find seamaster 344 arrived a couple of days ago.. It's with my watch man now though

 

Gorgeous piece!

 

You've been bitten my friend!
