WS 25 Battery change on MechaQuartz IWC Caliber 631 R397 (SR726SW)
No, I did not mean to skip the sequence of the watch work. But I felt you
must be curious now to have a closer look at this "very nicely jeweled" movement
as Adam in NYC (fellow PMWFer and Admin) put it. It is indeed a lovely movement
to look at and I am every time tempted to take new movement shots. If you do
watch work documentation you will probably feel like me: always torn between
getting the job done in a reasonable time while trying to get nice shots too.
While I tried hard this time, the white balance was not always set as I wish it
would have. Still, I think the picture gives you an impression of the beauty of
the caliber that combines a mechanical chronograph with Quartz precision. You
will note the little circled plus sign next to the Quartz crystal (left middle
of the picture), that is where you could adjust the speed of this Quartz module.
On the right hand and upper side you see the mechanical chronograph module. Please also note that I have already cleaned the edge of the case from excess silicon and some crust that I have found near the chronograph pushers. But you will notice that on the pictures to come that follow again the sequence of the work.
