Thanks to @JohnnyD for posting https://www.ozbargain.com.au/node/178139
The Orange version is now probably at historical lowest price. As @JohnnyD said before, the price will fluctuate like share market, but as of today, it is $24.99 + $12.10 shipping.
Quoting the product website:
"Sports Watch GPS Tracking S20 Slim Orange
The Navig8r Navwatch S20 is a GPS enabled watch allowing you to keep track of your runs or journeys for later review. The Navwatch S20 can show current speed, average speed, number of laps as well as time, date and a stopwatch function. It even knows the exact time for anywhere in the world you may be. Imagine getting off the plane in another country and having the correct time automatically updated to your S20 watch.. The Navwatch S20 connects to a PC with a USB plug connector and dedicated software. With the software you can choose to view your route / journey on Google Maps and review different segment infomation such as speed, time elapsed, calories burned and so on. With a smooth, slim line design, the Navwatch S20 has an easy to use interface and can also double as your every day time keeper."
I've had one of these for a year or two, works very well once it locks onto the GPS signal, bargain at that price.
