I have an Oris Aquis (black dial, bracelet, 36 mm, thank you for asking since 8 months, very happy with it. It runs within COSC specs but quite varied, from ca -3 spd to +6, with the latter seeming to be the normal deviation.
I want to get it regulated some day sooner rather than later since I have read about several ppl getting Oris 733 down to even better accuracy. Sure I'm fine with COSC but would like + 1-2 spd even more
Anyway, my question is about the (eventual?) anti-magnetic properties of the Oris caliber 733 movement. Does it have any such properties? If so, what can be said from an engineering perspective? I have also tried to find such info on the Sellita SW200-1 base movement, downloading full specs, but can't seems to find anything pronounced anti-magnetic about the SW200-1. But since Oris makes some modifications (which I personally have no insights in of which) I thought it is worth asking about this.
Thanks in advance.
