A very rare Lemania Mk1 1958 Nuclear Submarine watch. Caseback: 0552/924-3XXX 81193. With two dials. Comes with a 1 year mechanical warranty. These Nuclear Submarine Lemania's were produced in incredibly low numbers, with reports of around 450 pieces produced of the rare but more common Lemania Asymmetrical Series III. The Series II was produced in very small numbers (probably 200 max!) during a very short span before the Navy moved on to the Asymmetrical Series III. It is no surprise that these Subs are among the most desirable and collectible vintage military chronographs
