Help with potential first purchase - White 1680

[cchoi112]

Hello Everyone,

My first post!

First, thanks to all for the endless information on this site. I spent about half the day yesterday going through years of old posts on White 1680's and barely cracked the surface.

I'm looking at my first potential vintage Rolex purchase. A 6.1 serial White 1680. I would really, really appreciate all your expert opinions on this one.

Most important (to me), the dial really has me confused. My best guess is that it's an original Mk II but...
- the ever-so-slightly-open 6's...does this indicate service replacement?
- does the lume look like the "toothpaste" that was used on some service dials?

Other observations:
- the bezel appears to be a replacement
- the plexi looks too good to be 40 years old
- the lugs look heavily polished

Thank you again. Looking forward to hearing what you all have to say...
