Here's a wee curiosity for you. To the left is an "Orion" Jump Hour watch, made in Switzerland in response to the
sudden shift towards digital watches from and in the mid seventies. It uses a standard enough mechanical movement, hand wound and usually
off set within the base metal case. In this example the movement is atually quite small, could be from a ladies watch, and is offset using a specially designed spacer.
The minutes dial runs constantly just like a minutes hand on a conventional watch, but the hours
"jumps" over as the hours change.
This watch is a fairly chunky example, base metal case with Stainless Steel snap back.
Came as an intermittent worker - a clean and oil plus some general clean-up work produced this very wearable example. The strap is
a blue fake croco leather design to complement the blue faced dial.
An excellent retro design to seek out if you are into the "retro" look! There are various examples from a number of makers.

Depth 11mm. Weight 59grams.
Raketa 24 Hour Watch
One of the few true 24 hour watches made, the Raketa movement is set up so that the hour hand moves around the dial
once only in any 24 hour period. There are various models of this watch, some have rotating chapter rings with time zones
listed for different cities. The upper crown (at 5 hours position) adjusts the rotating chapter ring, the lower crown (at
7 hours position) winds and sets the watch as normal. Robust Raketa Russian made movement. For some folks, the 24 hour
dial is difficult, what can I say, I don't find it at all tricky, and it certainly removes doubt about " Military Time"!

Voumard Backset 2000
Voumard (Swiss) Backset watch. Crown and set from rear. Auto movement - calibre unknown.
(Backset movements can be tricky to remove, often through crystal.) Goldtone Base metal case, SS back. Date mechanism. Second picture shows
the knurled backset knob. Voumard is a generic Swiss make, one of many smaller companies producing various watches.
Voumard Backset 2000, Swiss Made Automatic. Movement unknown.
34mm diameter. 40mm lug tip to lug tip. Lugs 18mm. 9mm deep inc "crown".
Weight inc strap 40gr.
The backset "crown" pulls out one notch in the normal way to set the hands
and date changeovers. It is not obtrusive when the wtach is on the wrist, however I don't find using it when setting to be very easy or
