Also this watch is running -4 sec/day; I know it's supposed to be +/-2 but I figured in may settle in possible with more wear.
Has anybody else noticed this noise compared to the previous series of movements?
Thanks for responses.  |
There is nothing wrong with your watch its because now the cal 3235 has a ball-bearing rotor and this type is far nosier than the older sleeve type bearing.And your watch is not supposed to be +/-2 100% every day for life, all it means its been tested on a machine to a precision -2+2, and at time of testing the movement did meet that spec.Much like when they are still tested at the COSC to a AVERAGE -4+6 seconds to get movements chronometer certification result is at time of testing only just to state its passed. Testing to a precision on a timing machine to -2+2 in a controlled environment,can be different to how the movement could perform while on the wrist .There are many variables to over come ,first the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction, shocks, mainspring power-reserve and last the owners daily wearing habits.For any mechanical movement to run within a few seconds out of 86400 in a day truly is a mechanical marvel,
