Nice set of features. The case looks awfully similar to my square Nixie watch. I guess that's where the design converges to.
I'm still puzzled why other people need an RTC chip and a fast computer to make a Nixie watch. I can get excellent results from a PIC running at 32 kHz, keeping time in software to ~1 second per week.
