What brands regulate in 6 positions?

I had the misfortune of my SD43 running -10SPD when brand new in December of 2019. Within a few weeks, was running -30SPD. I had it serviced, under warranty, after one month of ownership. RSC took about a month to get it back to me. I received it back in late February of 2020. It's been running at a maximum rate of +1.5SPD since and when on wrist, will generally run about +.5SPD.
Even when I don't wear it, I keep it on the winder so that if something does wear prematurely, I can get it fixed within the warranty period. A little nervous. I've got a little over a year and a half left on warranty. Something tells me it'll take a crap on me just outside that period. Can't bring myself to sell it though. I love this watch. I'd have no problem paying for a service, but I prefer there to be a fix to it prior to going there. |

Well, after having my explorer repaired once after warranty (I received it back about a month ago), I decided to buy a timeographer (Weishi 1900).
From my reading of this thread, these amplitude results would appear perfectly normal, I believe. Am I interpreting this correctly? The watch was fully wound and in practical terms has lost 10 seconds over the last month. I would also like to thank everyone for their contributions to this thread: I’ve learned so much! Thank you! |

I have a few (minor) comments: - For your Weishi 1900 set the rate accuracy resolution to 0.1 s/d using the measurement range 99.9 s/d. Yours presently is set to 999 s/d; see chapter 6.6 in the timegrapher manual how to change the settings. Lift angle should be 53 degrees for 32xx. - Do not measure the 12U position, calculate X and D for 5 positions. - Repeat the measurements at t = 0 and t = 24 hours. |

32xx movement problem poll and data thread
Quote:
For that you need to do more measurements, e.g., every 12 hours after full winding, in order to get more data points: t = 0, 12, 24, 36, 48, 60 hours. Avoid to measure from 23:00 - 01:00 and 05:00 - 08:00. These are periods with reduced 32xx amplitudes. Example (below) two 3235 watches measured along the entire power reserve in DU position. |

32xx movement problem poll and data thread
Quote:
The data point you mention for the GMT BLRO (after 60 hours) is at a VERY low X-amplitude. At that time (BLRO, 60 hours) the power reserve of this caliber was already so low that a significant deviation from the isochronism linearity was the normal consequence, but the slope 'm' (as given inside the graph) was quite high until 48 hours during this measurement. I measured my Sea-Dweller (yellow/red dots) more frequently, as can be seen in the graph, its isochronism linearity was kept until 62.7 hours, which is better than for the BLRO. Maybe, the BLRO would also have remained linear between 190 and 160 degrees, but no data points were taken between 48 and 60 hours. I tried to illustrate this in the modified graph below. Note: I do NOT argue that this isochronism has to stay linear down to very low X-amplitudes! |

Thanks for the suggestion. I’ve read the #3647; looks an interesting experiment, which I will certainly do, however, I’ll need to wait a few weeks as I’ll be travelling rather a lot. |

Thanks! Looks like the pics only display in tapatalk which I don't use anymore. Digging through the html of the original post the images are hosted on a tapatalk server and referenced with an http url which chrome doesn't load due to cert errors.

Amplitude only: DU 328, DD 278, 6U 271, 9U 259, 3U 256. These seem somewhat higher than I might have expected. Presumably they’re at the upper end of expectations? |

32xx movement problem poll and data thread
Simple, I think these values are not correct for a 32xx movement, IMO.
DU 328° is certainly wrong, 300°-310° max for a 31xx. 6U 271° is more for a horizontal than a vertical position of a 32xx caliber. Repeat with the 'standard' procedure that was described many times in this thread. After full winding wait 15 min with the watch at rest in DU position on the timegrapher, then measure for 2 min. When you change the to the next watch position wait 1-2 min for stabilisation. All mentioned times depend a bit on whom you ask |

When amplitude gets too high a problem called knocking occurs where the escapement can actually spin so far that it crashes into its own backside. I think the first question is whether you are actually hitting those numbers or if this is some misconfiguration of the timegrapher.

A knocking (or rebanking) of the balance wheel would be visible on his timegrapher display and the movement sound could be audible. |

All measurements were within the expected range. Putting the timeographer away now and will just enjoy my watch! Thanks for the help |

What went wrong with the previous measurement? Do you mind sharing the newest data? |
