Made of tegimented, scratch resistant submarine steel. 44mm, 1000 meter depth rated and movement oils rated to extreme temperatures. At 18mm in height it wears tall but comfortably on my wrist. The blacked out seconds subdial gives the watch much more balance IMO. And I like the much easier to read enlarged minute chrono counter. Others may not agree about the last two points, but I think it gives the watch a unique and cool look. The left handed pushers take a little getting used to however. The first time I set my time, I did it backwards. Accuaracy has been about +2 sec/day. Not bad!
