Hi Ian,
Thanks, never thought about smartwatch applications. Looks like I'll have to
purchase a smartwatch for me to have a watch with the equation of time. But
I'll have to wait until someone produces a application with a dial that has the
EOT.
I notice that one of the android smartwatch application producers will add your
watch if you tell them what it is. Maybe we should ask them to do one of the
$30,000 EOT watches. That would be a lot cheaper.
Thanks,
Regards,
Roderick Wall.

hi Willy
As is the answer to so many things these days... There's an app for that
If you have a smart watch you can create your own watch face as you like it
with underlying code
For example
https://play.google.com/store/search?q=watchmaker&c=apps&hl=en
shows all the watch-face making apps for android smart watches
I only found one reference to EoT in the G+ forum for the first (WatchMaker) app
(The e-watch was a recreation of a two sided real watch with EoT but they
didnt' seem to have replicated the second side that had the EoT)
so there's a gap in the market to be plugged!
And in case anyone is interested . If you want a mechanical watch with EoT
here's a watch selling site with a search included
http://www.chrono24.co.uk/search/index.htm?query=equation+of+time&dosearch=true&searchexplain=1
But expect to be paying at least one kidney....

More interesting is to know whether there exist modern timepieces which
indicate the solar time.
With the possibilities of electronics and a built-in GPS system it can not be
so difficult.

Hi all,
This is an interesting website on equation clocks.

As explained by Fred Sawyer in a recent lecture to the British Sundial Society,
if often worked the other way around... people had an equation table and all
kinds of rules so that they could adjust their clock so that it matched dial
time for as long as possible.
Dial time was (and still is for some) 'true' time. The acceptance of local mean
time was a slow process. Likewise the acceptance of national mean time met with
a great deal of resistance. In Dorchester in 1858, in the UK, a judge in a
court case found in favour of the plaintiff, since the defendant was not
present at 10:00 o'clock when the case was scheduled. The court was using GMT.
The defendant arrived at 10:00 local mean time - a few minutes late. He
appealed and the appeal judge ruled...
"Ten o’clock is 10 o’clock according to the Time of the Place and the Town
Council cannot say that it is not,
but that it is 10 o’clock by Greenwich
time. Nor can the time be altered by a railway company.… Nor by any person who
regulates the clock on the Town-Hall."
Unless you lived in a (maritime) city, or had an astronomer on hand, or a local
rich man who went up to the city and owned a chronometer, there was NO way to
set a clock without a Sundial. It all changed with the the arrival of the
telegraph.... I have found that this is something that watch and clock
enthusiasts sometimes forget!
