VERSUS: Special Modern Sea-Dwellers

Tenth 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 special edition Sea-Dwellers. The Deepsea "D-Blue" reference 116660 and the 50th Anniversary reference 126600.


Which do you prefer and why?
