Trainmaster
Ball Watch's dress-watch line drawing on the brand's 1891 railroad origins. Cases run 38–41 mm, bezels are polished and unadorned, and dials carry the railway-station visual language — Roman numerals, sector-style layouts, power-reserve arcs. The Cannonball's 41 mm case and Roman-numeral power-reserve sector dial is the modern reference-point for Ball's heritage aesthetic.
