VERSUS: Vintage Sport Models (1675 and 1680)

Twelfth 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 a couple vintage sport models. The GMT-Master 1675 with fuchsia insert and Mk1 dial and a Submariner 1680 with Mk1 dial as well.

Which do you prefer and why?
