Powered by Heuer's caliber 12, a
link direct descendant of one of the first
link automatic chronograph movements introduced in 1969, this ref. 110.253B is as distinctly 1970s as their earlier manual wind siblings are distinctly 1960s. As an automatic rather than
link manually wound caliber, the case is necessarily more substantial, but the C-shape allows the watch to sit very comfortably on the wrist despite the added thickness.
