On “His Majesty’s Service” this tool watch has seen service from the ca. 1940s. The perfect “SWISS-only” dial is simplistic, legible and with “no frills”. The beautiful blued steel hands are completed with the super thin chronograph seconds hand. The movement (unserviced) runs very well with amplitude exceeding 300 and the hands reset to zero as they should. The high quality, signed movement is just beautiful. The detailing and use of different materials is so intriguing. These chronograph movements are works of art! The diameter is 50,8 mm and the thickness is 16,4 mm.
