    Re: Lindbergh-Weems Second-Setting Watch

    Dear Ed,

    Thank you for the illustrations, they do help but my main issue is/was with the bezzle rotation (direction and angle) to account the EoT value.

    In my opinion one should be able to set the rig for the actual EoT more precisely than to the nearest minute, so I expect the inner (seconds') scale rotates 60 times faster than the bezzle. Or should I just keep the EoT in mind and add/subtract it along with other angle values? I.e. - the bezzle rotation is not for EoT correction but for watch error accounting?

    I do not quite understand the

    ...Its clever design allows the second hand to be syncronized perfectly GMT seconds because the inner-most second face can be rotated to match the second hand's sweep, thus the watch's name Second-Setting...

    bit of the previous explanation. How does it help when my watch is, for example, 45 seconds late against UTC? All the rest of the face (and hands too!) remain where they were. How does rotating the inner scale to correct the going help? Rotating the face does not synchronise my watch - by my understanding at least.

    But the time-to-angle (UTC-to-GHA) conversion itself is clear.

    Thank you in advance.

    Warm regards,

    Tony
