Seiko Dolce 5S21

Timing Data

This watch has not been timed as rigorously as others in the collection. Partly this is due to the fact that it is not a HAQ and partly this is due to the extra difficulty in timing a watch with smooth gliding seconds. Motivation to track the timing of this watch is further diminished by the c.20 second lag in setting the time, due to a quirk of the dampener mechanism. Nevertheless, I have found that this nominally 20 SPM watch is running at about 5 SPM at the beginning of January, 2016, after 107 days of timing.
