Has anybody seen these before?
400 grams (1lb) of Steel/Bronze, that makes the Russian divers look tame lol.
It's called the Naval Destroyer, perhaps because you could take it off & batter the hull of enemy ships to sink them.
Why on earth would you build a watch to these specs that weighs a full 1lb & then fit a dial & hand set that looks like it cost a £1 though??
