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.
