IMHO, I think you can get a far better example for not much more. Here's one with a sparkle dial, as an example. https://forums.watchuseek.com/f29/omega-seamaster-chronometer-168-022-circa-1969-a-5134263.html
Yours isnt a bad choice either! Considering the little price difference between both. But the dial looks like refinished?
I was having a hard time to look for a decent on for 168.024. I don't know why, I just get attracted by the beads of rice bracelet for this particular model.
Looks like corrosion here:
I bought a one like that with a much smaller dial damage than yours, it turn out to had suffered a water damage
