... no lollipop and no inverted numerical scale. Early 2913 had inverted numerical bezel, and lollipop. On this one would have been wrong , because it is a 2913-3 of Aug 1958, too late for those. But ... have all the original bracelets (7077, 7912, 1506 and 1039) with proper endlinks (n.6, n. 516, 506 etc )
Perhaps an early 2913 will come at some stage.
