The stand on my desk that I use to elevate my work area is an IKEA SIGFINN monitor stand.

Before opening any vintage watch or clock for the first time I recommend checking it for radium paint. I didn't do that in this video because it wasn't the first time that I opened this watch. For more information on radium and how to check for it using a geiger counter see either of these two videos:

The NetIO GC10 that I use is no longer made. It uses an SBM-20 geiger muller tube, which is also used in the GQ GMC-300E and other geiger counters. If you find one of those it should perform similarly.
