The coin edge bezel has a ceramic insert, with your normal 60 minute dive bezel markings, and all the numbers and markings are coated with BGW9 luminous paint.
The dial of the Borealis Seafarer is undoubtedly Rolex DSSD style, with the same applied markers and a date window at the 3 position.The date window is outlined in white, giving some contrast to the dial and allowing you to see the date window a little better. It even has the stainless steel chapter ring, though, it is completely sterile, which is something I actually prefer. Because of the strong contrast between the stainless chapter ring and the black dial, the way it is done, does make the dial appear a little small for such a large case.
The sapphire crystal is 5mm thick and has a very good inner AR coating. When taking photos or outside in the sunlight I was able to see the dial very clearly with little, to no glare.
The hour, minute, and second hand are clearly Tudor inspired, specifically from the Pelagos. The base of the hands is black, with the rest outlined in white. These are what are referred to as snowflake hands, and they are filled with BGW9 lumiunous paint, as well as the markers.
On the case back, you have an engraved mermaid in the center. The screw down case back is done in a combination of brushed and frosted finishes, and for the most part is very well done. The back is domed, and it will raise off your wrist when being worn.
