Good Friday evening,

I put a westclox scotty on my timegrapher 1000 and it doesn't seem to register; stays on the preliminary screen that says "auto detect."  The timegrapher acted a bit funny today with a couple of other jeweled watches, where it started detecting but then went back to the preliminary screen, but ultimately it seemed to work on those.  I've only used the machine a few times.  Does the timegrapher not detect non jeweled watches or is something wrong with the machine?  Thank you and have a nice weekend.

in the autodetect mode is looking for a signal within a specific range or ranges's for a specific frequencies. This is where we could make a wild guesses probably 18,000 beats per hour and manually set the mode to that range.

Then one of the unfortunate problems with the Chinese machines it would be nice to have real audio. In other words how is does the watch sound? If the machines not getting a clean enough signal it can have issues with the signal that would be another problem.

The timegrapher is now working with the dollar watch.  I think the watch was running so far out of parameters that the machine wouldn't function properly.  I noticed that i hadn't fully wound the watch and once i did that the machine picked up the signal but i still got an erratic display.  Once i serviced the watch, the timegrapher seemed to work as i would expect.  Thanks guys.

Nothing is wrong, when a watch works erratically that is what the instrument shows.

      Hopefully if the issue is running costs, Mark would let us know and suggest ways of raising finance. If it's the other issue, which we are skirting around, sites can be passed onto others.   PS because I know you're all interested, I  had a bacon and mushroom sandwich for breakfast.  Hehe.

      Hi guys, the question is what is a forum, a place for discussion and passing on information, idle chat and a bit of fun and I for one are the richer for it. When in Hospital last year with the Covid being force fed oxygen and feeling total sh1t and close to the pearly gates a daily look on the forum to see what was going down helped to keep me focused on the job in hand took my mind off the problem for a short while but it was a lifeline for sure. We chat to friends for that is what they become around the world read their posts help where we can post information where we can.  I like @Neverenoughwatches some times think of members past and wonder if they are still at the watches or given up, some drop in for advise and drop out again never to be heard of again. The forum reminds me of Yorkshire hospitality, The door is always open and the kettle on the stove. Long may it continue.   My two bobs worth.

      Main spring

      By KenD · Posted

      Thanks all.   Movement is a Helvetia 800C. Don't know any history e.g. if the broken mainspring is original. Watch was bought recently as non-working. Really interesting piece that Jon, thanks. I'd only been thinking of length relating to power reserve. I don't have a mainspring winder (yet) so I'd like to avoid winding the spring into the barrel by hand. The old spring measures at 1.60 x .11 x ~290. Sorry, can't be exact on the length. The piece I still have is 275, but the second piece escaped during measurement. Best measurement I had for it was ~13. The micrometer does zero accurately so I'm pretty confident of the .11 Also, I'm getting the barrel ID at 9.5 on a vernier. I'm now wondering about going with a .11 spring? Given all of the above, maybe 1.60 x .11 x 300 x 9? Any thoughts? Cheers.
