Hello, I am selling my Borealis Sea Dragon, which is a very well executed Tuna homage watch, at least as far as the case design goes, the dial is nothing like the Tuna Monster lines so it has a style all it's own.

This has long been sold out, and this one is in perfect condition, I cannot find any signs of previous use on it, but will list it at 95% just in case. I think you will find it to be perfect as well because I use magnification to inspect my watches and am VERY picky.

This is the Grey Dial with orange accents, a very sharp one with a bit of color, it comes on an isofrane style strap that is really comfortable, has very nice brush finishing on the case, with polished chamferred edges, all the little details like large signed double knurled crown, signed buckle and a nicely engraved mermaid caseback.

I do not have the original case it came with I bought it like this the watch by itself on the PU rubber strap. You won't be missing anything as Borealis uses a cheap soft side case with foam rubber that is barely bigger than the watch...

Here are some specs:
