Purchase advice on 5513 & 1665

[accau]

Hello all, I am fairly new in the vintage world and this would be my first vintage purchase, I have been reading threads after threads in this forum about vintage knowledge, but still I have a lot to learn.

I’m currently traveling in Tokyo and came across theses two watches, would appreciate to get some first glance advise if I should go forward or give it a passes and keep hunting (both piece are price in similar range)


Sorry about the lack of photo, as it is hard to take picture with the lighting in the store, most of them turn out all blurry.
