Dear forum members! I have one pocket watch movement, the plate is very similar an omega movements, but has some different. (i marked this with red arrow on first picture) The movement signed: H White Mfg Co Piccadilly London. I searched information from this watchmaker on internet but i found no, just H. White Manchester. On the 2th picture i marked the trade mark, this is similar to Julien Gallet trade mark. http://www.mikrolisk.de/show.php?site=280&suchwort=Gallet&searchWhere=all#sucheMarker It was relationship between manufacture Omega and Gallet? What is the truth? If anyone has information from this movement, please share with me. Thanks!
