The stopwatch function of the SwissMicros DM41X

is this E-Ink display

No, it's not. But similar to E-Ink, the LCD display is able to hold an image for a long period of time when powered down. The DM41X manual touches on this.

Its called "transflective memory LCD display", I think it needs very low energy and can thus stay on without draining the battery.

I wonder which people need their scientific calculator to have a stopwatch feature. Rally copilots? Airplane pilots? I don't know, but it's a curious feature indeed.

Physics teacher and a billion other professionals. Another application: Measure runtimes of 41X programs (as there is no direct way to get the tics from the cpu). Even though it's true that for most applications one could use a smart phone app instead. Anyways, the Hp-41CX is legend, so the DM41X is a must have electronic gadget for 41X enthusiasts. I mean, why do people drive vintage cars when modern cars are so much better? ;-)
