Portuguese seconds @ six reliability - a random data point

[wtchgk]

So far the most specific concrete data I have seen regarding the operation and reliability of the rep Portuguese seconds at six movement were time grapher results before and after the movement was serviced.

I wonder whether anyone has data like ‘time of continuous non-stop operation’ between service and failure.

Out of curiosity I placed a 3714 after being fully serviced on a watchwinder whenever I was not wearing it. The winder was an Orbita and all the correct settings were used for the movement. The watch failed after three months. The problem was as expected with the transfer gears. After removing them the rest of the movement continued to operate perfectly. This obviously is just a random data point. Given the design of the transfer gears I imagine other results may vary quite a bit.

Perhaps others have concrete data to share.
