Recently I purchased an old OMEGA PLOPROF 600M with its original mesh strap near Liege in Belgium and I was curious to whom it belonged 2 in the first place. ( first owner's name was engraved on the back ALAIN RODRIQUE ) I Googled his name and found him on facebook. I was totaly blown away with this man's deep diving carreer. DEMINEUR NAVAL BELGE ( belgian navy demining service from 1976 - 1979 COMEX DEEPSEA DIVER 1979 - 1995 I am very proud to have spoken to this gentleman in person and very honoured to know about him. This watch has been on his wrist for countless journeys ... if only the ploprof could tell us everything it saw. Offcourse this watch is not a comex prototype but simply a heavilly used toolwatch and worn by a senior comex diver. And for me thats a plus every day off the week a small piece off deap dive history on the wrist. Just wanted to share that with all the forum members. This is my first post and I hope some off the readers can give me some extra information about this watch and I hope this wasn't a boring 1st post. Regards Isi from Belgium.
