Hi..
I have several watches which exhibit the same "problems" as you have mentioned.
My watches include those with central second hand and those with small second hand at six o'clock position.
Once the second hand and the minute hand are synchronized, it will start to deviate over time and return to being synchronized after the minute hand returned to the same position when first synchronized.
I do believe (purely my take of the problem here) is due to what Aditya mentioned above.
The dial is slightly placed out of the exact centre of the minute/hour hand pinion. The outcome is the minute hand will be seen to return to the exact position (relative to the dial) once in every rotation.
BTW - those watches of mine that exhibit this seemingly error are reputed to be of the highest quality, PP no less - and of the limited edition with limited production. I did not bother to send it back - the watch remains accurate as the movement is not the problem and I really do not need to keep time to the second in my life. /W72
Minute Hand and Second Hand Do Not Sync Through the Hour
Following is a post I made today to the Help Desk Forum. I am repeating it here because I was uncertain of the proper forum to raise this question. I apologize for the duplication. ************************************************************* I have encou...
Hi Joehank,
I don't have the technical answers you are seeking but I think the manufacture was trying to relate the fact that imperfections in the teeth of the gears can translate into slight changes on the rotation of the seconds hand pinion. This change in rotation...
Thanks Mike
Thanks, Mike. Your response is far more intelligible than that of the manufacturer. I appreciate the input. I looked up the Volker Vyskocil V-30; a very impressive watch. Had I known of it before my last purchase I might have considered it and saved some ...
This is more thinking aloud than an opinion...
... First of all, we must understand that in most watches the minute hand is fixed to the cannon, which in turn is snapped on to a wheel in the power train. Therefore I can see no reason for any slop here, since the centre wheel (on which the cannon is sn...
Thanks Aditya
Aditya: Thank you for your response. I don't believe that the first part is applicable since the second hand is not attached to the center post but is contained in a offset subsidiary dial. I will try the dial test you suggested. Joehank
some technical explanations
Hi Joehank, I've been asked by a colleague watchmaker to chime in on the questions you raised here. The problem you describe is not exclusive to any one brand. In fact, there has been much diiscussion about this subject on many watch forums. There is a sm...
Is your watch always horizontal when testing?
I don't know of the mechanics, but I wonder if the play in the gearing will mean that the watch minute hand will appear ahead in the first half of the hour (eg at 15 past the hour) and behind in the second half of the hour (eg at 45 minutes) if you do you...
Can you take photos demonstrating what you are seeing?
While my experience agrees with Jack's explanation - some watches have more 'play' in the minute hand and after setting the watch it takes a few seconds (let's say 15-25 seconds) for the minute hand to start moving - I think you are describing something d...

Thanks to all for the responses
Sorry I have not sooner respond to your posts. Life sometimes interferes with our other "distractive" activities. In this case, it was spending time with my grandchildren that took precedence over getting an answer to my watch question. That normally will...
