Good day, I'm pretty sure it's been re-dialed. It has a porcelain dial. I'm researching the case hallmarks so please no spoilers I'm trying to find out which Calibre this is. It measures 27.96mm on the micrometer so call it 28mm. Some have said yes, its an authentic movement. Others have said I have a frankenwatch. I would appreciate any information on this little fella. Thanks in advance!!!
