    Universal Geneva 28 jewel pocket watch

    This site was a big help to me last time. This time I recently purchased a stainless steel pocket watch by Universal Geneve it is market Automatic Microtor on the face and "Universal Geneve Swiss 215 Microtor" 28 Twenty-eight jewels on the movement. I found out about a similar wrist watch, but can find no mention on the internet about a pocket watch.
    The movement is 28 mm. The face somewhat larger.

    I've never seen one either. The movement must be the same as used in the wristwatches - Polerouters. See:

    Please don't PM me to ask for a valuation - I won't attempt one.

    Thanks Marrick for the reference. It does seem odd to me to have an automatic pocket watch though. Would it get enough movement sitting in a vest pocket to keep up its power reserve?

    Good point... maybe that is why they are so rare!

    Who is the company behind it? Why are they using this material?

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    I have for around a year already a 1950s Eterna-matic Golfer. Only once it failed to keep its power, when I did not wear it for a while weekend for being sick. It is rated at 47 h reserve.

    As Leandro said the most popular is the etherna golfer and I haven't seen a Universal Geneve with this feature before. In fact experiments with automatic winder in pocket watche occasional are done over mainy years in different aeras. The first was Abraham-Louis Perrelet 1770, annother bigger serie was buid in the end of the 19Th century by Loehr and with modern wrist watch movements by etherna and as we see Universal Geneve. But under the line in a pocket watch a automatic winder can't work efficient.

    In particular, a microrotor would not be as efficient (Dr. Ranfft once described the microrotor as a ladies' movement squashed to the size of a gents' movement or something like that).

    This makes no sense. The efficiency of a watch does not depend on being swung in a wrist. What does change is how long it will take for it to wind. Early experiments had watches fully winded in pockets after fifteen minute walks. It boggles the mind to think of a healthy person who does not get that much walking time per day — and that was before the Eterna-matic rotor bearings and the rotating office chairs on wheels.

    HI leondro , do you've link to these tests. Personal I just know what a friend told me who is crazy collecting these Loehr pendules (https://watch-wiki.org/index.php?tit..._Patent_03.jpg). His experience differ to these tests but these watches are more than 100 years old with a pendule weight. It would be interesting to see how the modern rotors movements works in a pocket.

    Regards Silke

    Addition: Another funny aspect ...pocket watches with automatic winding addition are earlier developed than a crown winding system to replace the keywinder. But they don't conquer the market and pw out of the earlier aera are very rare and expensive peaces.


    Addition II : Funny I found the link and it was about very very old watches

    Google-Ergebnis für http://www.datacomm.ch/rbu/per-aut1.jpg

    Any ideas why they don't conquer the market ...it could not be the price.

    Something went wrong with the first image.

    I guess wristwatches were just more practical and fashionable, specially once one did not have to take them off for winding.

    Perhaps there was also a coincidence between fashion and technological development.
