    Re: Lindbergh-Weems Second-Setting Watch

    Dear Ed,

    Thank you for bearing with me!

    Finally I dug out the (very lame) Longines' explanation of their L699 caliber...

    May be I'm totally wrong, but I see NO "innovation" or enhancement in making this part of watch-face movable - how do I know if the watch on the picture you've posted is 12-seconds fast or - to the contrary - is it 48-seconds slow?! In my eyes it looks like a not-very-clever idea. How should I interpret the other hands' positions? They no longer correspond to real/meaningful time.

    A stop-second arrangement is far better approach - with an initial setting to gain some reasonably small time, - so that one could just stop the watch to wait for the time-mark on the radio and release the mechanism. All my quartz wrist-watches do gain ~10 seconds a month, but they are too cheap to implement the stop-second feature properly. It must be done with a separate position of the clock winder: extracted to the first "click" it must stop the watch, and only in the second "click" it should engage the gears to set the hour/minute hands. If extracting the clock winder did not upset the hands on my watches - it would be perfecto.

    OK, now its' all clear with this watch. Thank you for all the explanations!

    Warm regards,

    Tony

    PS

    Could you please post the PS source of the scales? I'd like to modify it for the 24-hour watch.
