It all started with the need for an accurate standard for the home lab. 
I had one of the Racal double oven standards for years, but a pot core 
transformer on the inner oven control board went open circuit on one 
winding and was unable to fix it at the time. Then bought the Z3816 on 
Ebay, which was working fine for years until the oscillator EFC became 
unstable and of course, then one thing leads to another.

As for clocks, have a collection of synchronous motor clocks awaiting 
restoration and a couple of pendulum clocks - A gents pulsynetic and an 
IBM clock from the 1940's, quarter sawn oak case and all. I do embedded 
systems here and the IBM master clock is appropriate - an example of how 
IBM didn't only build computers. It's a work of art, with thick brass 
plates for the mechanism and much of it gold plated to reduce corrosion. 
The self winding mechanism had a broken bracket on the solenoid 
armature, metal fatigue over the years I guess. That's been completely 
stripped, cleaned, sparingly relubed and now working as it should.

So, not really an obsession, but definately a growing interest area :-)...
