Thank you very much for the excellent article!
Finally I got the idea behind the seconds-setting design. My problem with the idea was because I never let the hour and minute hands to get out of sync with the seconds hand: when setting my watch I always stop the seconds hand on 0 mark (12h00m or 24h00m depending on the model), moved the other hands to the proper marks - and let the watch go on the signal. For convenience this requires a watch with faster going.
Initially I thought that the rotating bezel or central scale was used to compensate for the watch's going - and I wondered how that could work at all - for a watch with synchronised hands this rotation would wreak a total mess in the time-reading...
Now it is absolutely clear - the rotating bezel is a simplistic alternative to the stoppable seconds hand - just as your article perfectly describes. If puling the crown out (for watch setting) was stopping the seconds hand this rotating dial or bezel would not be needed at all.
And when the time-to-GHA convertion was introduced in the later models - that rotating became meaningful again.
Thank you one more time!
