The mechanism flushes away oxidation every 10 minutes so it does produce an electronic display worthy of the large Nixie tubes. I thought the 6 valve version with the seconds flashing away would be too distracting. It is an amazing piece of engineering with a great back story on the internet, YouTub
I have to thank you for promoting this clock. I bought one relying upon the fact that you had invested in one - it had to be the best quality! It arrived with a week and is amazing. Thanks for providing the maker’s name.
