Man of Honour
It doesn't have any self healing properties. The titanium itself is not scratching, when titanium is exposed to air or water it reacts and develops a thin titanium dioxide layer. This layer is what you are seeing marking easily.
I was under the impression based on info online back then that there's a factory coating that acts as the self healing layer which is why light scratches heal themselves. On my Pelagos I had light scratches every now and then like from cuff buttons on a jacket and within days would see them vanish.
How often are you guys manually adjusting the time on your automatic watches? I find it irritating that my watch is losing circa 1 second a day, but don't fancy re-aligning it everytime I wear it.
1s either end a day is excellent accuracy that not many watches can manage. You could re-sync every day or just re-sync once a month with that kind of accuracy. Every automatic watch will gain or lose time each day. Zenith are the only watchmaker who have the most accurate fully analogue movement. Something like 0.3s a day for 95% of the power reserve. Keep in mind that as your power reserve levels drop, accuracy will also drop as the mainspring gets weaker like an alkaline battery on its last 10% of capacity. So just give the crown a few winds if you're not wearing the watch for a day or two to keep reserve (and accuracy) up.
