Model 222-RR in ‘Box Car’ style. Model 25 copper moire guilloché dial Model 25 with silver swirl Roland Murphy demonstrates how to turn a guilloché dial by hand on an old rose engine machine railroad watches that feature so-called Box Car style dials. RGM explains that in 1925, Ball introduced a new official RR Standard dial referred to as the Box Car dial. It had plain, sans-serif, heavy hour figures to help make the dial extremely easy to read. Waltham offered a similar dial, also calling it a Box Car dial.  Elgin and Hamilton also used similar dials on some railroad models. The new models’ blued steel hands are true to the classic form. Finally, RGM now offers Model 25, a 40mm classic design similar to the firm’s well-known Pennsylvania Series watches. This series features character- istic coin edge cases and truly hand-cut engine-turned guilloché dials that are mesmerizing to see up close. These American-made dials can be had with a choice of guilloché patterns and galvanic colors. RGM fits the cases with top-quality examples of the workhorse ETA 2892-A2 automatic movement.   Visitors to the anniversary weekend also saw the RGM Chess Watch, which the firm debuted earlier this as its first anniversary piece. These four new watches, plus the new movement, make 2017 the brand’s most prolific ever. The debuts are a fitting way to celebrate a quarter century of watchmaking at RGM.
