American watchmaker Roland G. Murphy, whose eponymous Pennsylvania-based RGM Watches pioneered independent watchmaking in the United States, has teamed with renowned watch photographer and artist Atom Moore to create a terrific limited edition series of ‘Fat Arrow’ military style watches.

The series, the Equation of Time Fat Arrow, reprises a late 2021 prototype developed by Moore and Murphy’s Equation of Time division, which specializes in watches designed with input from collectors. Moore’s original dial art piece “Fat Arrow” is based on the name given to the World War II-era watches with the larger dial arrows, which were used to signify British military equipment.

Starting with Moore’s Fat Arrow dial design, Murphy devised a complementary steel-cased 36mm military style watch.

As a result, the new Equation of Time Fat Arrow features a matte black dial, large crown, sword style hands and a ‘railroad’ minute track set with luminous dots and markers. Luminous material is also found on all the larger arrows on the dial.

As with many of RGM and Equation of Time offerings, customers can customize certain aspects of the Fat Arrow, including the finishing style on the case, crown and hands.

Visible through the caseback is a manual-wind Sellita SW210-1 finished with Geneva stripes and radially brushed gears. Price: $2,995 (limited edition of 99).
