I'm looking for an insanely small laser. Basically my project is turning an old wristwatch into Sterling Archer's "Omicron Spymaster", his spy gadget watch from the TV show Archer. I've got the watch, a 1973 Omega Geneve which looks very similar to the one in the cartoon. Here's a picture to compare.

I've got all the tools and skills to build the face, crystal and integrated garrote (strangling wire). I just need to find a laser small enough to fit inside. Preferably a higher powered one but I'm not concerned with burning things as much as it being eye-catchingly bright (definitely leagues above 5mW). I can either aim the laser upward through the crystal or out through the watch body James Bond style (it's never shown on Archer, so I can choose based on where I can fit a diode).
The inside dimensions I've got to work with are 28mm diameter and just over 5mm depth (maybe I can stretch this by doming the face upward). If I can find a flat laser so that it can point out through a lens on the face (disguised as a date readout) and crystal, that would be preferable as it makes concealing the garrote wire easier. How big are laptop Bluray diodes? Keep in mind I need to fit the battery, diode and any regulation inside this space. I can make the crystal out of polycarbonate, acrylic or PET (which I'll be cutting to size digitally with my Hackerspace's 60W IR laser cutter). The big challenge here is getting the laser through the crystal without cutting or etching it over time, so wavelength will be important.
