Decima MAS Strumento Model XZ 221-001

This is Decima MasTM Strumento Model XZ 221-001 born from a collaboration between Ennebi Company Mr. Alessandro Bettarini and Mr. Yves Odier. Decima MasTM Strumento XZ221, is a professional diving instrument and a timekeeper which derives from the 1988 concept (Subacqueo Stagno 1000 Metri, destined for Military use), designed 2003, developed 2005 and produced 2007, by Time To Time Projects (France) and Ennebi (Italy). The Decima MASTM Strumento XZ221 is born from desire and passion, and, to bring forward artisans and experts know-how in a chosen selective style. Embedded with symbols of valor of the Italian Military frogmen 'Incursori' special unit, this instrument commemorates an historical event of the past, in which a handful number of 'sommozzatori' frogmen demobilised and destabilized the enemy forces without endangering any human lives, for this heroique action, officers and sailors were officially highly decorated by both nations, (Alessandria, Egypt - December 1941)

I think it as an exciting diver with connecting to the history of heroism of Decima MAS divers as this SE is dedicated to commemorate the heroism and valor exuded by Emilio Bianchi during that famous Alessandria port raid in 1941. IMVHO besides being a looker and a functional dive instrument I can't attest personally how very comfortable it is for it’s size in daily use.
