By TLex The Blancpain Fifty Fathoms as we know it today (launched in 2007) pays tribute to the original Fifty Fathoms watch that was first developed in 1953. These early models more specifically the Aqualung model or 'BUND no RAD' watches were issued to the German and Polish Military (from the 1950s up to the 70s) used radioactive material on their dials.
In order to reassure those who bought the civilian models that theirs were safe and weren't using radioactive material Blancpain placed the 'NO RADIATIONS' icon on their dials.
The 'NO RAD' icon on the 2010 Tribute to Fifty Fathoms is a cool little enhancement to what many would say is already the prefect dive watch and one that should be left well alone, however for me it reinforces the amazing pedigree and heritage that the Fifty Fathoms has, it adds a further point of interest and a sporty splash of color, I really like it. One further change that the Tribute version has over the regular 'FF' comes from its increased minute markers, which now run complete round the bezel.
Only 500 pieces of this version will be released. The 2010 Tribute to Fifty Fathoms utilizes the same 1325 calibre as the 2007 model.
