Davosa Watch Argonautic BG Grey Mens 161.522.90. 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.
