Omega La Magique - Cal 1357

I have a fascination with this caliber.

So far I have not seen any listings for scrap parts. Only been searching a few months.

In the mean time I got an equinoxe reverso ca 1655 to play with, which is from the same era. This is the one with analog on one side and digital on the other. Mostly I play with 134x quartz movements. I have been building some testing equipment with old AVR processors. Giggle AI wikipedia et all gave me some interesting code for driving lavete motors, which I have yet to try. I did measure the coil. Building up the courage to power up the circut to see if there is any activity.

The 1655 maintenance data sheet just arrived yesterday. Was interesting to see that shares some ca 1365 wheels. The disassembly procedures were informative since there were some mysterious 'earth pins.' Which I now know the function of. A 1357 maintenance sheet would be most informative.

One Idea I have is to convert an old apple watch case into a similar mystery dial movement. I did start tracing over some online photographs in an attempt to work out the gear train tooth counts. Which If you had and were willing to share I would be most interested in. I can sort of tease them out of photographs what I have traced over.

Your photographs are most informative.

The disks on the original are sapphire. That requires some specialized grinding equipment.

An Idea I had for replicating the disks would be to use some iPhone protector screen glass. I was even thinking about such this afternoon. The laser is not good at cutting glass. On the other hand a hollow tube grinder might be able to drill out a disk. The outside tooth ring would need to be cut in the traditional way, So a number of them would need to be made at the same time.

Mostly though I am building up a digital model as to how such a movement might work.

Thank you for the additional photographs.

I forgot about that one. Usually I post that link on these type of thread.

Some of the sheets do detail more of the electronics pulse timings etc.
Looking in my research folder I see there is no base data sheet, although one can sort of infer the part numbers from other movements.
I did find the following information for which I took screen shots. Would be interesting to know where the source data came from.
I get thie impression these were never made in anything other than gold. Which makes finding any scrap parts unliklely since they would have long been melted down.

If these numbers are correct, this has to be amongst the rarest watches out there.

This was my first attempt at mapping the train tooth counts.

Interesting you mention vapor deposition. One of my friends back in the 1990s built the machines IBM used. I got him to give a lecture at trade shows. Another branch in the rabbit warren of things that would be fun to make. The star projector at the California Academy of Science in golden gate park, used a process to make the star plates. I also have an interest in obsoleted APS cameras and related automated film processing machines. So from time to time play about with camera lens restoration. Nothing that sophisticated. My friend also introduced me to peristaltic pumps and valves (which he used for a bar bot drink making robot back in the 1990s.)

Last year I found some online templates to cut such pumps and valves with the laser. I am finding the fiber laser to be an interesting tool, with a lot of potential, if I can figure out how to keep things from warping and burning up.

Vapor deposition (sputtering) could also be fun for making custom LCD glass displays. Back in the day when I had access to glass painting kilns I tried grinding a display up and melting it down.

I worked briefly for the guy who patented transparent indium tin oxide switches, which were used in teaching calculators. What could be used on an overhead projector which were used for showing view graphs. Clever guy. made a deal to license TI calculator tech. Since a classroom needed 30 calculators to the teachers demonstration. He was also one of the first to outsource manufacturing to china, when that market opened up.

Does give one an appreciation for the tech that goes into these things.
