One of the four known examples of this clock, it is a design of the utmost art historical importance, rarity and beauty. Stylistically similar to work by C. R. Mackintosh, Josef Hoffmann and others of similar stature, its simplified though visually compelling modernist presence demonstrates not only Knox's awareness of the advanced trends of the time but also his superb mastery of them. With it Knox moves beyond Art Nouveau and points towards the future evolution of the history of design and the styles of the Bauhaus, the Machine Age, Art Deco and the true Modernism, all of which celebrate clean line, rectilinear surface decoration and simple yet extraordinary form.

Another example of this design, the first ever to appear at auction, was sold at Chrsitie's New York on 11 June 1999, lot 370.
