Style, precision and comfort align in the EDIFICE EF527BK-1AV. Under the veil of its black IP stainless steel case and band, lies a calculation tool.  The 1/20th second chronograph and rotating Slide Rule inner bezel allow for measurement and calculation of such values as time, speed, fuel consumption and more.  The watches smaller band segments are rounded to hug the wrist more comfortable and a knurled bezel, precision dial indexes and mineral glass give the timepiece a stylish look.
