The Decima MAS 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 valour of the Italian Military frogmen 'Incursori' special unit, this instrument commemorates an historical event in which a handful number of 'sommozzatori' (frogmen) demobilized and destabilized the enemy forces without endangering any human lives. For this heroique action, Italian officers and sailors received the 'Medaglia D'Ore al Valor Militare' (Gold Medal of Valor) by the Italian Government, (Alessandria, Egypt - December 1941).
In 1945, during an extraordinary ceremony, Crown Prince Umberto of Italy was about to pin his nation's highest decoration the 'Medaglia d'Ore' on de la Penne's chest. From those in attendance, a man who like Sir. Winston Churchill regarded his old-adversary as a man who was an extraordinary example of courage and genuity, stepped forward, Sir. Charles Morgan (Vice-Admiral), former skipper of the Valiant and said: 'Thanks to de la Penne's warning, not a life had been lost among the 1700 Valiant's crew'.
Decima MasTM Strumento XZ221, is a professional diving instrument and a timekeeper which derives from the 1988 concept for Officine Panerai (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 XZ221 Strumento is entirely produced at the Ennebi (Italy) laboratory by highly qualified and experienced engineers, as well as artisans and expert operating staff to achieve a high quality level expected by both professional and discerning amateurs. We guarantee that the Strumento XZ221 is manufactured with extreme high levels of precision. Its production is set at one instrument per day allowing strict manufacturing, precisions and immersion test check list for each singular piece.
The Swiss movement calibre F2560 housed in the Strumento XZ221 is chosen for its precision, reliability, durability and resistance to shocks. The movement is mounted in a secure technique allowing further shocks to be absorbed. Final movement adjustments and precision tests are made at Ennebi (Italy) laboratory before and after the movement is fitted into the instrument-case.
