Grand-Seiko SBGR079-anti-magnetic-watch Grand Seiko came out with this assortment of Magnetic Resistant watches around 2012. This includes mostly brushed finishing to the cases and bracelet, as well as the hints of red color on the dial. The mechanical automatic Grand Seiko SBGR models contain an in-house made caliber 9S65 and have cases which are 15.3mm thick. That is a serious enough difference that they wear larger. Ideally for me, it would have a 40-41mm. While it will not affect most people’s lives, it is important to know that the automatic version of this watch has a different magnetic resistance than the quartz version. Also, the automatic Grand Seiko SBGR079 watches have the same amount of magnetic resistance as the Rolex Milguass. On the dial of the Grand Seiko SBGR watches you see that the movement is shielded to 80,000 A/m (ampere per meter) which is roughly equivalent to 1000 Gauss. Look up the Rolex Milgauss and you’ll see that like its name implies (mil = 1000), it is resistant to 1000 Gauss. Of course, the two are bested by Omega’s Master Co-Axial – but that uses different technology.
