Wittnauer 6002/5 - thoughts?

Hi all,

I'm interested in acquiring my first vintage chronograph watch and this Wittnauer 6002/5 caught my eyes.

I was doing some background research and it seems to be a decent one for my first vintage watch. The only negative thing that I can see from my newbie eyes is the lume on Arabic numerals are pretty much gone.

However, before I pull the trigger I was wondering whether I can get opinions about this watch (any red flags which I should be concerned of)

Thank you.

Nice looking watch! Do you know if the chronograph function works and if the chrono second hand resets to zero? Servicing chronographs are more expensive than time only watches.

According to the seller, all chronograph functions working and the watch is running and keeping good time.
