Well done Adam. Looks like a nice bit of kit.
Looks good in the wooden box. At first glance I thought it had a Nixie readout...............which would've been cool
I recently got a Vibrograph M80, which I've been playing with whenever I get a chance. I eventually got some new digits, so the readout is now complete.
I also had to change an IC that controlled one of the digits.
Mine has a separate pickup/microphone which you hang/clamp the watch on. Just placing the watch on the pickup like yours is a lot nicer.
