The Rolex presidentfrom it's inception has always been very expensive. A halo flagship designed to appeal to the "men who change the world."
180*** Single Quick-set Rolex President vs 182 Double Quickset Rolex PresidentThe 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.
