The MTSigma watch is MdT first diver's watch, faithful to the aesthetic codes of the brand with its open back. Its unique design adds a new dimension to MdT range of watches.
 
The MTSigma is the brand's first watch designed to become a work tool for professionals, particularly divers. Its unidirectional bezel allows the diver to  properly calculate the immersion time and decompression stops along the ascent back to the surface. 
 
The MTSigma is undeniably a diving instrumant, but above all it remains a Maison DuTemps creation which must meet the brand's aesthetic requirements. The combination of its black dial, its silver hands and its red second hand gives it a unique charm.
