Paul Reinman (1557-1609) was probably the son of Heironymous Reinmann (fl. 1554-1577), a highly regarded Nuremberg compass maker of whom Syndram comments: "Reinmann ... gehörte zu den bedeutendsten und erfolgreichsten Kompaßmachern Nrnbergs in der zweiten Hälfte des 16.Jahrhunderts, dessen Arbeiten auch dem Kaiser bekannt waren" (p. 79). It was Heironymous who first used the "crown" maker's mark (Gouk's mark 10, present on the diptych of 1558 described by Syndram as item 12, pp. 77-9), and subsequently used by Paul, who maintained the high standard established by his father: Lloyd judges that, "The quality of Paul's instruments, many of which are finely engraved and have gilt brass fittings, reinforce the impression that he was a wealthy craftsman who could afford the best materials and workmanship for his diptychs .... [his] work represents the apex of the Nuremberg diptych dial. His instruments are notable for their visual attractiveness as well as for their technical accuracy". He also notes Paul's contribution to the development of the genre: "It was Reinman who first extensively adopted the practice of ornamenting the diptychs with fine decorative borders and engraved figures and scenes which were apparently taken from contemporary pattern books, prints and emblem books" (pp. 43-4).
A very similar diptych dial by Reinman dated 1607 in the Nuremberg Germanisch Museum is described and illustrated by Zinner (p. 489, plate 28, figure 3).
