Well for watches the true LED for me; versus OLED as pictured above, although I did purchase the First Fossil OLED watch. I find the display rather disappointing.
The collection has grown as these get restored but I do like the LED watch:
As far as night viewing goes, the HP-01 is my cockpits, lowlight environment (actually daytime and nightime). Especially with the raised tactile buttons that allow a simple memorization of key mapping. The display is bright and RED allowing for no disruption of night vision adaptation; a requirement in the South Pacific flights with no full moon. Radar returns do not show icing or ice crystals so running with the cockpit lights off and the background lighting on low is imperative at night for cloud avoidance.
I use the HP42S for my cockpit as it is slimmer then the 41CX (my favourite LCD calculator) but at night I need to shine a map light on the display. The HP-67 however does not need a map light and with my programs mapped to the top 5 buttons I have access again to a simple memorization of key mapping.
As far as the HP-15C LED version, well using an alpha/numeric display such as in the 9825a, increased memory, a timer/clock function it was done for fun 8-)
However, my favourite creation would be an OLED backlit:
- a colored alpha numeric two line OLED display (backlit ability)
- increased memory and speed
- a dynamic timer/clock/beep(alarm) function
- 15C physical format
- USB facility
Excuse the colour choices, but a two line HP42S display with alpha on a similar menu type would be good.
Enjoy but don't stare at the OLED display too long
