The Swiss Sellita SW 200-1 automatic movement in its screwed stainless steel case keeps perfect time on the way down. Scratch-resistant, anti-glare sapphire crystal guarantees a clear view of the tidily designed dial with its 15-minute scale on the bezel inlay to provide orientation in an emergency ascent. And thanks to the extension to the stainless steel strap with a safety clasp, the DAVOSA Argonautic BG Automatic can be easily worn on top of a wetsuit.
The state-of-the-art Super-LumiNova BG W9 luminous pigment ensures exceptional luminous properties. This material has been applied to the figures and hands, and now for the first time to the 15-minute scale and all the figures on the ceramic bezel. Under natural light, this best-in-class luminous pigment appears white; in the dark, it shines brightly and clearly in clear blue.
Thanks to a manual helium escape valve, a controlled equalization of pressure inside the watch can be achieved when ascending to the surface. Moreover, the valve at 10 o’clock has been technically optimized and is now clearly identifiable thanks to the helium symbol on the crown face.
This watch is a really high class diver. The only two negatives are the strap being almost impossible to size, and the second hand is hard to read. Outside of that, this watch is a amazing! The lume is great in the quality and amount of lumed parts which is basically everything except the date window, the bezel is great, and outside of the second it's the most legible watch day or night that I've ever owned. The bezel action is second to none. As I mentioned, I didn't like the strap, but because the space between the lugs is straight and not curved like most watches, any aftermarket strap will look custom on it.
