What is this old Tudor? Real? Fake?

[Reluctantly]

Hi there,

I've had this watch lying around for ages. I can't find any pictures of old Tudors that resemble it and was wondering if anyone can help with identification. (Nothing looking like this comes up when I search for this model number). Is it likely to be authentic? Fake (what would be leading indications that it's a fake)? A ballpark estimate for the year if it's authentic?

There are two number on the back of the case: a five digit number and a four digit number below it. The numbers appear to be 14885 and 4463.

Any words would be much appreciated. Thank you.
