Angular Momentum Dive-Tec/500 Watch

Why is it over 316L? Because this type of steel has a special resistance to the corrosive and discoloring effects of salt water - which is nasty stuff. Just live on a coast and see what water does to thing that are exposed to it for long enough. Caseback of the watch is not screwed down, but instead has a thick sapphire crystal as the caseback which is specially sealed using a unique gasket. It is not user removable, but needs to be taken into be opened up. Angular Momentum says this style of caseback offers superior water resistant security than a screw down caseback. Plus the caseback will remain water resistant after other types of casebacks on diver watches need maintenance to ensure resistant to water seeping in. The crystal comes in different colors (all lume actually so they glow brightly), or it can be ordered to be transparent for a view into the automatic Swiss movement.The stye of the lugs represents Angular Momentum's new Time Gallery style case, and looks interesting on a dive watch. Really helps add heft to the case which slightly reminds me of those popular large Russian style diver watches. Adding to the tool-like composure of the watch is the brand and bezel retaining screw. The crown of the watch is meant to look like a valve release - nightly reminiscent of dive tools. Angular Momentum is about to release a sensational dive watch the likes of which I've never seen before. Most of Angular Momentum's design are polarizing, so I don't expect each of your to like this watch, but enough of you will appreciate the interesting concepts that went into it. Like the Pita Barcelona Oceana watch, this is a uniquely artistic rendition of a dive watch that is art, but also heavily focuses on diving utility. So just because it doesn't look like all the Rolex Submariner clones out there (and Rolex Submariners themselves), does not mean this is not a admirable diving tool. So lets jump right into discussing this new Dive-Tec/500 watch.The 46mm wide case (by 17mm thick) is done in Staybrite 1.4435 NCu steel that is higher quality than 316L stainless steel used on most steel watches. Rolex Sea Dweller watches watches (especially the Deep Sea) use Staybrite steel as well. It might be the same formulation.
