Rolex Double Quickset Feature Development - 1989

The President's Day Date from Rolex has two inner wheels to contend with.  Not only does it have the date wheel but also the day of the week wheel to manage.  The Day Date with no quickset would be very time consuming to push through the date and day sets in order to get to the appropriate calendar and week day views.

However, the quickset features allowed the date to be adjusted quickly.  Yet, with the Presidential Day Date, this was not enough.  There had to be a separation between the Day of the Week wheel and the Calendar month wheel in order to have the power to easily set either the week or the month independently.  So, Rolex came up with a solution - the Double Quickset Feature.

The single quickset feature was added to the Rolex President Day Date reference 18038 in 1977.  It was powered by a new caliber 3055.  Besides the single quickset feature, it also came with other enhancements including the sapphire crystal.  

However, it wasn't until 1988 that Rolex updated the Day Date to include a caliber 3155 that the double quickset function appeared.  The 3155 allowed the Day Date owner to independently manage the day of the week wheel and the day of the month.  This was far more practical than the single quickset and has been so solid that this caliber is still in use today in its Day-Date 36 models.
