There was a bit of software called the "Windows Timing Machine", but it had many flaws and doesn't appear have been modified at all in the last 10 years. The second is that the analog signal from whatever pickup you design really needs some filtering before it is digitized to keep the software task minimal. The first problem is that the timebase in your typical computer sound card isn't particularly accurate, although it can be calibrated. It is somewhat difficult to do this purely in software. Then after fiddling with that for a while, gave up and bought one of the relatively inexpensive Chinese made machines (you'll see it at the bottom of the page linked above). In the end I cobbled together my own setup: The movement before finally sealing the case with a new gasket.I did a pretty extensive search 2-3 years ago when I first got into this hobby and came up empty handed. I also replaced the old watch strap spring bars with new ones (judge for yourselves which one was the new one.).Īnd some time later the cleaned and lubricated movement on the timegrapher: I also glued the hour marker back in place and I renewed the luminous paint on the markers and hands. The diassembled case before cleaning and polishing.Īnd.wooshh.the polished case and crystal (took me quite some time.): The force is still strong in this watch.(at least the long mainspring is still nicely "S"-shaped). Well then, below, all the parts before cleaning: In the end I decided to omit this part entirely and I assume that it is not really vital for the function of this movement. It can block the setting lever under certain circumstances which then prevents re-insertion of the winding stem.quite a no-go actually. Here the already mentioned spring came out:Ī disturbing detail of this movement is the part I highlighted below: On the right - encircled in orange - we see the noted powerful spring. There is significant tension on the spring under the blue-encircled area here, beware -)Īnd yet another spring (on the right, it is somewhat hard to re-set it during reassembly): somewhat later I have removed most of the parts:Īnd with the day disc removed, we see a complex setting mechanism (there are some delicately serviceable springs here btw, this can be annoying). The glue residues under the "free flying" hour marker ring. Under the ratchet wheel one of the many springs inside this movement (this is the click spring btw). Without the autowinder, the movement looks and works like a conventional handwound timepiece.Īs noted above, the crown wheel is held in place by two screws, this is the shorter one. The three screws that hold the automatic module in place (one of them is slightly longer -> it fixes the crown wheel): Under the rotor, yet another implementation of a bidirectional automatic winding mechanism - and not a stupid one. The timegrapher indicates that a watch service is necessary: Thanks to the still quite intact sealing of the case, the movement looks a lot better. The removal of the old Rallye watch strap reveals some dirty details -) It´s quite worn with lots of scratches on the crystal, and the hour marker ring came off, too.

This is a late 1960s / early 1970s watch from Tissot.
