A white dial keeps this Clifton Baumatic close to the Classima's restraint, though the calibre underneath, BM13-1975A, sets it apart: 21 jewels and a 120-hour power reserve, enough to run for five days without winding. The steel case sits between 30mm and 40mm, finished with date display and water resistance to 5 ATM. An eight-year warranty extension reflects the movement's build quality, and the watch suits business meetings and interviews through to dinner.
