Garmin Forerunner 745 Watch - Black
Currently half price (RRP $929.99) at Torpedo 7 but also available on The Market if you have coupon codes/free shipping etc.
Previous lowest price was $579 according to pricespy.
You could also try price beat at Rebel Sport for an additional 10% off if it works.
Thanks! I have been eyeing up a Garmin watch for a while now. Was keen on the 745 but was put off by the price. Just managed to get it from Rebel for $415.80 with their 10% price beat!
