Another completed project. I am calling this the Vostok Adventurer.
Powered by a Vostok 2416B 31J automatic movement and on a strap meant for a Timex Expedition.
My inspiration is the Seiko Alpinist; Green dial and compass bezel.

Curious - what took you from watch collector/enthusiast to creating your own pieces and really getting in to mods?

Interestingly, I found another way. I use a microphone with a free audio software called Audacity.
When regulating movements: I place the microphone near the balance wheel and record the audio for a few seconds in Audacity. In the software I choose to view the spectrogram of the recording. The beats show up as vertical lines distributed in time/ By zooming in on the lines, I can measure the time between the beats. For a 6Hz (21600bph) movement, the time difference should be 1/6 seconds. From the two levers for adjustment, one controls the period of oscillation (this is the one that should be adjusted when regulating) and the other controls the difference in time between swings in each direction (typically called the isochronism lever). By adjusting the levers, recording audio, and checking the timing, I make sure that the swings are the same and the period is correct. Once I am happy with the result, I record the audio for a longer time (20-30seconds) and make sure the beats are aligned. If fast or slow, I adjust the regulating lever (not the isochronism).
It has worked for me so far.
In fact after I finished this watch, I found that it was running about a minute/day fast. I assume that it was because the movement was previously regulated with slightly larger hands. The lighter hands meant that amplitude of the swing had to be adjusted. The watch is running spot on again ;-).

Hello friend! Haven't seen a wrist check from you in a long time. Hope all is well.
