separate research path that I am engaged in on the Blancpain 1315 caliber compared to recent Rolex calibers. Keeping it VERY brief as this is/is not tangential to the 32xx caliber. BUT the 1315 caliber is known to retain a 100+-hour power reserve while delivering startling accuracy over time. It does invite a comparison of Rolex 3135 -32xx- and BP 1315 movements as to their respective qualities, an activity that I am currently engaged in. {Please excuse this insertion, in the interest of horological research.} SD |

One month old Submariner 124060. If the average is within Rolex specs, and each position individually is within COSC specs, that means it’s all good?

32xx movement problem poll and data thread
Quote:
PS: "perfect" because 4 of the 5 rates are positive and one position (3U) is negative. With such a caliber regulation you are able to compensate, either gain or loss during a day, by choosing an appropriate rest position overnight. In addition, the 2 horizontal and 3 vertical amplitudes are very similar, which is the result of a very good movement regulation, including a positive X (average rate). |

So 12U is not regulated by Rolex, right? Because the rate in that position was -5.5 s/d, amp was 234 deg and beat error was 0.2 ms. Out of curiosity I also did the measurements for our almost 2 years old OP34 (2232) and our 1 year old DJ31 (2236): |

The paper copy below was posted 2 years ago in this thread. Look at the 1st criterion for the rate. The maximum Delta is 9 s/d, for COSC this would be 10 s/d. |

Good, you should not move the watch in-between (you certainly know). Keep it in DU position. You could continue taking measurements after 12,24,36,48,60 hours to get an idea about the amplitudes along the power reserve, as others have done before in this thread.
