The Nethuns Ocean 300 OB312 is a spectacular bronze watch. The most obvious perk of the watch is the material: it's entirely made from CuSn8 bronze. Bronze has the great attribute that it builds up a layer of patina. This is an ongoing process which makes every watch unique. Discolouration is normal with this material. One major benefit is that you can largely bring back your watch in the original condition by using a Cape Cod cloth. 
The sandwich dial has a great green tone that fades to black at the edges and it's protected by 3.5mm thick sapphire glass with an AR coating, which helps with the impressive 300m water resistance. 
Under the hood you will find an automatic Seiko SII NH35 movement. This is reliable Made in Japan movement, that hacks and can be wound be hand.
