3 of my favorite in the collection! 

I sold on most platforms for me I have most success on watchexchange at Reddit. There’s no fee and a lot of potential buyers, especially for Bb58 if you put it below market price. 
 

There are rules like providing a timestamp and price but fairly easy. I do suggest to use PayPal goods and services when making payment

Whatttt I’ve been looking for the Milgauss, not as popular as I thought I guess

Awesome watch! Love the green of the piece. I too purchased one already this year 😂

The black bay 41mm is a great choice, also I’d go for a longines master collection 

Man that’s such a cool picture OP! this is definitely my most worn watch 2021
