Re: New watches aren't supposed to do this - are they?

two things spring to mind (although I am not a watchmaker):

1. potentially the watch came in contact with a magnetic field and has
become magnetized. A watchmaker can fix this problem. Think back to
where you've been. Was the watch in your pocket or on your wrist whilst
being near a large generator, electrical motor, or another powerful
electrical field?

I don't know any way that could have happened... The watchmaker who looked
at it thought maybe there was oil on the hairspring but there wasn't, and no
coils were sticking together (as they might be if it was magnetized).

2. The hairspring is regulated by being held between two pins on a
regulator which when moved have the impact of lengthening or shortening
the amount of free hairspring and thus speeding up or slowing down the
watch. I have a new tissot pocket watch with the 6497 movement (which I
love a lot!) which ran fine the first day and then sped up to gain about 2
minutes a day. I took it to my watchmaker who regulated it back into
time. He suggested that perhaps when it was initially regulated that the
regulator pins might have been pinching the hairspring and holding it at
an abnormal length and with the millions of flexings of the hairspring in
the first day it eventually came free and went to the wrong length, thus
the difference in time. It now runs perfectly and with daily use has only
gained about 10 seconds in the past week and this is a pretty stock 6497
movement.

This sounds like a possibility. It would have to be some oddball thing like
this I suppose. Much better that any theory I could have thought of.


Regardless, two minutes a day is unacceptable. Either return it to the
shop where it was purchased and ask for a replacement, or take it to a
watchmaker and see if they can get it back into time for you.

Cheers,

Alan

Thanks for the reply Alan. At least I'm not the only one who's had a strange
occurrence of this kind. I was beginning to think maybe I'm jinxed or
something.

I would be looking at the curb or regulator pins to see how much space there is for the hairspring, if they too wide apart it will cause the watch to lose and limit how far to move the regulator to alter the rate, in other words you have to move the regulator a lot further than normal to make a change, the pins should be adjusted so they are straight and parallel to each other and allow just enough space so the hairspring will not bind when the regulator is moved. ...
