No bumpers or oscillating weights. Batteries, solar power or kinetic would probably have gotten you burned at the stake for watchmaking witchery. Instead, there was just good old-fashioned finger-power. No wonder people were fitter in the old days. It sometimes feels as though hand-winders have rather dropped out of fashion.
But there are plenty of reasons to love a watch that you wind yourself. Thinner movements, fewer parts to go wrong, and no spinning weight to obscure the interesting bits. There are several patents on file for other Peseux automatics, but the and its brother seem to be the only ones to have seen the commercial light of day. Eleven years later, inBerner was turning out more thanmovements a year. There are just three bridges—one for the escapement, another for the going train and the third for the mainspring and winding mechanism.

In fact, until the advent of the Alpha, you could have had a Stowa Antea KS and a Nomos Tangente, both with impeccable Bauhaus design credentials and almost functionally identical movements under the case back.
If Nomos went Bauhaus, Blancpain went bling. The Paudex maker gave it a serious makeover as their Cal. Not only did it get day and date wheels, but also a moon-phase instead of the sub-seconds.Many also enjoy the winding ritual. The faster we careen into the digital era, the more significant these little analog rituals become.
My better half considers winding a quiet way to recenter herself, to connect with something simple, real, and benign. These watches are big on style yet restrained and versatile.

With meters of water resistance, this is a Dressy Tool Watch of the highest order.

I've seen this version around and was wondering about it. The plate that holds the minute wheel in place would appear to be the key to this. The captive minute hand will prevent the cannon assembly falling forward, so when the hour wheel is in place and the minute hand is fitted, it will keep the whole lot together.
If the watch is originally made as a skeleton as opposed to being skeletonised by an enthusiastthen the manufacturer would have made it so that the hour wheel can't come off. You could fabricate a spring off one of the dial side screws. Use clear plastic to make a dial, the dial with movement ring also serves to position the movt in the case.
A clear dial of the correct thickness would help. You could also skeletonise the original dial. Hey bobm12I have a similar skeleton problem. I took a skeleton Asian and cased it in an Otto Frei 10 case, and have been having a hell of a time keeping the hour wheel from slipping ever since.

In my mind, if you could get your hands on one of those and the movement is of the family you may be able to use the same plate interchangeably. As Anil said, they usually have their own solution when first acquired Do you have a picture showing the movement and trouble area? It might be helpful in case I or any other member can help.
No dial needed. Unless they are cheap Chinese clones It's been a headache. The keyless works is a mess, too. I'll note that that tiny little brass washer in the photo did NOT come with my movement, and that's probably the source of my problems.
Meanwhile checked my skeleton movement, it has that hour wheel retaining plate. But the surprisingly missing it as can be seen on all pictures google pops out. Yeah I checked my S last night and noticed the plate. The is 12L 27mm diameter. Do you know where I can find movement casing rings plastic or otherwise for something like that?
