It was a gift. Farmers like to get full value from their equipment.
There is a time display on my phone but this only helps if I happen to be carrying reading glasses. The Casio watch I have reverted to, is permanently set to GMT because of the agricultural raw material jammed under the push buttons and also requires glasses.
Studying nature can be more useful than relying on diurnal variation eg. queue of cars on the bypass = it must be a weekday and 8.00am - 8.30am. also rash of ladies walking their dogs = it must be 3.00pm and nearly time to fetch the kids from school.
There are probably more but one does get so reliant on *knowing* to within a second or so the actual time:-)
