.... the sphere of air is filled up with non-Rolex and insted, if it can be counted as one, an IWC Pilot Chrono in view that it is anti-magnetic. Apologized for my ignorance but is Rolex GMT Master or GMT Master II anti-magnetic? If not, can we consider it as a Pilot watch? You can also go beyong the sphere of Air and into Space using the Omega Moonwatch...haha.. cheers..
