I was flicking around the web and one of these unusual looking 1960s doctors watches caught my eye. I would like one just for the novelty looks. So I then spotted three on ebay, one by Edox, one by Favre Leuba and a third by Doxa. They all look identical apart from the maker's name on the dial. Does anyone have any info on these? What do you think? (both watches are from different Indian sellers) Is this generic model branded by multiple watch makers at the time or just them being re-dialled with famous names?
