Rolex President Quickset vs Double Quickset 180 vs 182 and 1182

The Rolex president

from it's inception has always been very expensive.  A halo flagship designed to appeal to the "men who change the world."

For whatever reasons Steel Sport Rolex' just took off in terms of used value vs the Gold Rolex models (aside from rare ones).  The low residuals mean buying a modern solid Gold Rolex is not terribly expensive.  Someone once calculated the melt weight of a Rolex President is approximately 1/3 to 2/3rds the total cost depending on the market which means there is a lot of value in the President line.  Let's look at two that posses great value:

180*** Single Quick-set Rolex President vs 182 Double Quickset Rolex President

The Single Quickset Rolex President ran until the late 80s.  The difference between the single and double quickset don't seem to be great, since the day and date are both instant changers (e.g. they don't do the slow "9pm -3am date change" the date and day flip instantly simultaneously.  The advantage of the double quickset seems to be in setting vs a completely different movement but I will check into this. 

Both Rolex President models feature Sapphire Crystal and similar case dimensions.  1182 has solid presidential bracelet which should be reliable and less prone to stretching vs early Rolex Presidents.
