Polerouter Microtor supposedly Ref. 20357 - original or not?

Dear UG experts,

I fell in love with the Polerouter Series and am thinking of adding one to my collection. Being the first UG and not knowing every detail of these watches, I kindly ask for your help evaluating one specific piece I came accross for authenticity and general condition. I did read through several, really really helpful post here in the forum and other sources in the internet and came to the conclusion, that this could be a quite desirable piece. However, as mentioned, I am no expert and appreciate your specialist's eyes checking in it, too.

Thank you already in advance.

All looks correct and original based on what I can see from these photos.

Thanks @Mazoue for you swift reply. Unfortunatelly I do not have better photos available, but will have a look at the watch in person within the upcoming weeks

Unfortunately not. It was sold to another buyer shortly after my post here, but I am currently sourcing another nice looking specimen and hope to succeed early next year. Would let you know.
