Joepete Skrev:The entire construction of the MM300 is aimed at this watch being a diver´s watch that can be used for professional use. I know that it would probably not be used professionally nowadays, but it has it´s roots in the professional dive world, as it´s "forefather" (300m 6159 Hi-Beat driven monocoque piece) was close to being made "upon request" - different story, sorry

In the above, the L-shaped gasket has been introduced and Willy is totally correct, when pointing out that the antimagnetic feature of the MM300 just adds to it´s term as a professional diver

I have not been able to find a cross section drawing for the MM300, but only for a 1000m professional Tuna. In the link below, Tokunaga explains, amongst others, how anti magnetic ability is achieved in the large shrouded diver´s. I am pretty sure that antimagnetic ability is similarily achieved in a MM300

Citat:

IWC also built their divers without the helium valve.And they built the most anti magnetic diver ever made to this day.The Porsche design diver built for the german frog man special unit is an incredible piece of engineering.Rix watches in frankfurt have one for sale 15.000 euro.I read the story about how IWC built this watch unbelievable.It is totaly anti magnetic . willy
