Our reference is the 18038, which was part of the next generation of Day-Dates released in 1978, at its launch replacing the famed ref. 1803 and updating the President towards a slightly more modern style. 

At its core, the ref. 18038 is the quintessential Day-Date, complete with its classic namesake dial configuration, solid gold 36mm case and fluted bezel. This updated version did, however, feature a new watertight construction, now designed to be water resistant up to 100 meters, in addition to a sapphire crystal to better scratch resistance. On the dial, a wide variety of configurations were offered with this reference, but compared to its predecessors, the edge of the dial was no longer sloped downwards in a pie pan style; instead, they were flat. 

The most useful upgrade for this reference was the addition of a single quick-set date (not day) function.
