Someone is going to tell me that I need to invest $300 in a certain book, but until then, a question: Looking at some NOS hands for my 105.003. Won't be perfect, but not too expensive and a step up from current. Confibulated by some hands for sale which look to have kosher period packaging, but are labelled as '0861ST1450022 Omega hands, white, painted radium'. Manufacturer is JBorel. Did a quick google and there is a JBorel watch parts supplier out of Kansas City that has been operating for 93 years (Co. name font style on packaging and shop website looks identical). Can't imagine a US firm manufactured parts for Omega, so maybe aftermarket parts manufacturer? The radium is a bit confusing as I gather radium was phased out in ~1960 and the 861 didn't come in until around '68? Lastly, can anyone tell me the difference in luminescence colour / appearance between radium, tritium and super luminova. As ever, thanks in advance!
