Man I love the Polaris.
The PSO-1 looks like it originally had a sort of hammertone paint job? Is that correct?
I think I can see what you mean in photos, but in person it's got a sort of sparkly luster that shifts with the light - the patterns seem to dance around faintly as the angle of the sun emphasizes different directions of the lines. Almost like how mother of pearl behaves, but much less intense. It's very pretty for a scuffed up piece of overpriced steel.
I've just gotta say... I love it when you post pictures of this watch.
