Hublot Big Bang Tantalum Mat

Big Bang Tantalum Mat is a chronograph by Hublot.

This 2007 presented version of the 2004 published success model Big Bang with self-winding movement is dedicated all over to the unusual and rare material tantalum, which ensures a cryptic-discreet appearance. Hublot speaks with the "Mat" series about a "monochrome/monomaterial" concept. Again, like the sensational Big Bang "All Black", the game of graded metal and grays develops its own mysterious charm.   Both case and also bezel are manufactured from the skin-friendly tantalum (which, by the way, like platinum, is also extremely difficult to work with and whose occurrence is also lower than that of gold). The dial is mat gray; the indexes and numerals are made of tantalum. Like with all Big Bangs there is also an easily adjustable rubber strap with folding clasp, and the watch is waterproof to 10 atm.
