There's more models here: https://www.tkmaxx.com/uk/en/search?q=nixon&sort=publishedDate-desc&facets=stockLevelStatus:inStock&page=0 Including the black & silver version of the one I posted.
Not that I'm aware of but that doesn't mean it's not a thing - it's a long time since I was in the surfing crowd! However, most Nixon watches for women are smaller than the men's oversized ones and therefore have the crown on the standard right hand side and so would normally be worn on the left wrist anyway.
But girls wear the watches on the right, no?
It's a 50mm watch, the crown is on the left to prevent it digging into the hand, especially when wearing a wetsuit - same with most Nixons. Nice find for trendy, surfer dude 300m watch - heat.
Looks like a watch for young surfers and action sports. The crown is out of the way.
