I am in the process of building a new website for the Seamaster 1000 and I think the reference books on this model are wrong ,can I therefore ask ..Has anyone ever seen a watch earlier than 1974 ? and has anyone ever seen a caliber 1002 as is claimed for all watches prior to 1975 ? The archives appear to be missing a number of s/n and the entire write up of this watch in most books is riddled with conjecture and unsupported ‘facts ‘ I think it is without question in the early prototype phase the 1002 was the caliber for that watch as that was the only one available prior to 1973 but I have no evidence it went into production with that iteration in fact quite the reverse All help gratefully received Thank you in anticipation
