Rare antique military Navy silver OMEGA 24h day/night black dial pocket watch

  

Rare antique military Navy silver OMEGA 24h day/night black dial pocket watch. Amazing 2 tone silver case with gild trim. High grade lever chronometer movement, Breguet hairspring, precision regulator, hand finished and polished plate, adjusted to positions. Different gearing, with a 24 to 1 reduction! Nothing has been ever changed or replaced!

Perfect working order, keeping exact time. Special 24h day/night indications military black enamel dial. Has 24 hour dial notation on the dial. That means that the movement has to be altered so that the hour hand doesn't go in 360 degrees around the dial in 12 hours, but rather in 24 hours. The hour hand, in my example, would only show 1900 hours.

You'd know for sure that it was early evening. Conventional 12 hour watches have a "motion work" involving a 12 to 1 reduction in the gear train from the minute hand.

24 hour watches have a different gearing, with a 24 to 1 reduction. To be very technical, the motion work is the small 12-to-1 (or here a 24-to-1) reduction gear train that turns the timepiece's hour hand from the minute hand.

It is attached to the going train by the friction coupling of the cannon pinion, so the minute and hour hands can be turned independently to set the timepiece. It is often located on the outside of the movement's front plate, just under the dial. IT COMES WITH CERTIFICATE OF AUTHENTICITY! Auctiva Offers Free Image Hosting and Editing.
