Here the same.
How i do it, i don’t know, but my watches look mint.
Friday morning i dropped my watch on the floor.
I pick it up and see that it’s running fine.
After one day, no time fails, so RT keeps it’s promise that they make robust watches.
The inca block did work as it should be.
I heard about the scratch magnetism of the Santos.
Not that i am afraid to buy one, i have the same watch behavior as you.
