A keen hobbyist, he had a tendency to buy the latest and greatest gadgets of the time (like me) and the Cronus 3-S was supposedly the epitome of technology back in 1978. An accurate LED stopwatch, the unit uses 3 AA batteries to provide a bright display using (you may recall) those tiny LED displays with huge magnifying lenses of them, so beloved of Clive Sinclair.
There’s an advert here for the original model, “Cronus 1” which you’ll see in the link is a lot more primitive. “The most accurate, rugged, compact and complete competition stopwatch in the world, period”. The fact is that even then it really wasn’t that big a deal, a crystal timer and a bunch of simple TTL logic driving a display but hey, making oversize claims worked for Clive Sinclair, why not for these guys.
I did think of simply burying it – but hey – someone might find a use for it.. so..
