Hi all knowledgable Omegaphiles,
I have just acquired a 2004 Speedmaster Auto and it appears that the small seconds hand is not able to be stopped to set the time accurately. The large seconds hand is the chrono one and can be returned to zero and started on the second. Am I correct in this? The instructions in the book are fairly limited.
Thanks in advance for any help.

The tiny seconds hand is just there to let you know the watch is running 😉.

There are hacking moments, where the mechanism is stopped in the time setting position, but the Speedy Auto is not one of them.

Some movements can be "hacked" by very slowly applying backward pressure on the crown, but this depends on the caliber, tightness of canon pinion etc.

Thank you JiminOz, I thought that may be the case. Is it going to harm the watch if I use the large second hand as a normal one and synchronise it with the correct time?
Thanks

Running a chronograph timer hand continuously is frowned on by every watchmaker I heard from when I had a problem with a Gallet chrono with a faulty pusher. I can’t imagine it’s recommended for Speedmasters.

I go to ridiculous* lengths to try to get the seconds hands on my non-hacking automatic watches synced up with Internet time. I wait until just the right moment to snatch them out of the case and start setting them. It only serves to remind me how much time the watches lose in a day.

* Then again, as a watch enthusiast, I’m fairly immune to ridiculousness at this point.

That's what I am trying to find out, the accuracy.

When you say Speedmaster Auto do you mean Speedmaster Reduced using one of the the compound movements or the model using the 7750 based movement? If the former syncing the second is very tricky, if the latter, I believe it should actually hack so your watch may have a problem. The name Speedmaster Auto is used by Omega themselves for the latter.

Cal 1532 is a quartz 3 hand movement. It is not used on any Speedmaster AFAIK.

My mistake, I picked up the wrong card, let's try cal 1152.

Ok that is indeed a 7750 based movement used on the Speedmaster Date. AFAIK it should hack, your watch may have an issue.

Thanks

Are you pulling the crown out as far it will go? The running second should stop in the hand setting position.

My Speedmaster Automatic, caliber 1152 (bought in 1994), stops small seconds when the crown is extracted, making easy to synchronize it with Internet time.

Thanks all,
I just sorted it out. Must have been the nut behind the butt. I'm now a happy man.
Very helpful responses and much appreciated.

That second sentence casts everything else in this post in a disturbing light. Whatever that is, I urge you to have it looked at.

It is a shooting term here in Australia. Someone who can't hit the target, and blames the gun. Real problem is the nut, behind the gun butt.

There seems to be a few pilots on the forum. In their parlance the term would be "pilot error".
