VERSUS: Vintage Subs

Seventh edition of the "VERSUS" post/picture. What is "VERSUS"? Well, I thought it would be fun to compare two watches (and only those two watches) and discuss pros/cons by outlining the differences and getting folks' ideas/thoughts/opinions on TRF. We got folks here that have been collecting and studying these things for decades all the way to those who are just starting to venture into the crazy world of Rolex (and everyone in between). Therefore, it would be fun and educational!

For this edition, we have a showdown of vintage Subs. The classic 5513 and its brother with an additional complication, the 1680.


Which do you prefer and why?
