I have. They are masterpieces of technology.
They have about 13 buttons and 8 small dials in addition
to the luminous time inc second hand.
I gave mine to a physics student, but he then had some sort of nervous breakdown.
Anyway ... how many litres in a yard ?
That's not as daft a question as you think. About 0.5 I reckon - depends where the yard is from.
If you want to know what time it is where grandad lives - anywhere in the world - I can recommend Breitling World Time at :
it's free and only a 6.38 mega download. Comprehensive unit converters and much more.
Also here's what a yard is ... History of beer.
Enjoy !
