I have this one: https://www.ozbargain.com.au/node/762175 and paid over $400. This one for $380 is good value and I don't really see it getting lower because not many retailers carry these two models. I prefer my colourway, but this one is nice too.
The only Seiko Prospex with no date afaik, which I prefer because I don't like setting the date. Also solar for convenience.
