Cal 89 logo

Hello everyone,

Just get a IWC cal89 18k shark fin 37mm from 1962 movement. Case is from 1964.

Nonetheless i suspect the dial specifically the  logo was restored. The  “Co” lettering is unusual.

Can you please give your opinión about that  ?

Thanks for your answer. Never saw a IWC script with that “Co”
