Description goes on about being a countdown timer. Maybe a silly question, but does it tell the actual time and is there a stopwatch and alarm too?

The timer has various countdown and standard timer features such as stopwatch and tells the time. At the the end of a countdown it can be set to start counting up as well. Mine doesn’t have an alarm but the countdown has quite loud audible beeps at the marker points. For all the features, search the internet for the instructions, they are out there.

Does it have a backlight for use at night?

I apologize for the delay. unfortunately not!

what is the width of the watch strap please? 20mm?

The srap on the Optimum Time Big Sailing watch is 30mm wide.
