I’ve featured a Cosmotron GX before – Number 33 in the series – but I have a second example. This one grabbed my attention since it has an unusual dial, featuring a textured green finish and contrasting white chapter ring:

As with the Hisonic tuning fork model, the second hand sweep is very smooth, at 360 beats per second. The hands on this GX are nicely finished, with white centres, and are a little clearer in this shot:
