It does look original but it looks more brown to me than red. Quality took a nose dive on the 1970s models so be sure to look closely. While you are inspecting the movement, note the lack of any decoration and the sticker with serial number, they sometimes fall off. The 10xx movements work ok but they just look cheap. Cheap as chips.
btw I initially didn't like the big M in the logo, but I note the other watch in the now deleted post had exactly the same so now I'm thinking that how these came. There was a fashion for redialling these in mad bright colours in South Korea but I'm thinking this is legit. If this is being offered in Seoul though, be worried!
