Dave Jones (EEVBlog) implemented an RPN mode in his "µWatch" - a DIY watch / calculator kit he developed in 2008. Wayback machine has the details here..

That is really impressive, and... how do I put it, aesthetically challenged. I think my friends would hurt themselves from laughter if I wore that.

It's now 16 years later, and surely the technology has improved. A question for smartwatch owners (no one in my friends and family circle has a smartwatch): Is the screen large enough for a usable calculator keypad? I guess the home screen needs to show about 12 buttons: 0-9, DecimalPoint, and a +/-. The app could then swipe Left/Right for the other buttons: ENTER, EE, X<>Y, RollDown, +, -, *, /, etc.
