These are quite nice and the pricing is great considering they still have ETA inside. (Since 2010, when ETA announced they were cutting back on distribution to non-Swatch Group companies, ETA prices have been rising rapidly.)
Ocean Mariner - $600 (There's a used one on WUS for sale ~$350)
Here's essentially the same thing wit Sellita inside. I wouldn't be upset about that at all. $300.
Cave Dweller 2 -- More of the same. Miyota (Citizen) inside. $500 to start and goes up. Lots of dial color choices
Harpoon - Slightly different styling. Miyota inside. $650.
