Solving a watchmaking problem 

 four centuries old 



Combining rare beauty with de- 

 pendable accuracy, the Gruen 

 Verithin illustrated above is one 

 of the finest examples of the 

 modern watchmaker's art. 



For four centuries one of the 

 most important problems of the 

 watchmaker has been that of reducing the size 

 of the watch without the loss of strength and 

 accuracy. It was not until the Gruen Watch- 

 makers Guild conceived the Verithin wheel 

 train idea that the complete solution of this 

 problem was reached. 



With a simple rearrangement of wheels that 

 saved half the movement space, without reduc- 

 ing the size or strength of parts (see wheel 

 train illustration), the Gruen craftsmen set a 

 new standard for precision accuracy in a 

 pocket watch of beautiful form. Thus, in the 

 Gruen .Verithin — America's first accurate thin 

 watch— has been solved a watchmaking prob- 

 lem four centuries old. 



How the Gruen Pat. Wh-eel 

 Construction made an accu- 

 rate watch logically thin. 

 It isn't a Verithin unless it 

 is a Gruen, 



In picturesque Madre-Biel, Switz- 

 erland, master craftsmen, with 

 the aid of American machinery, 

 fashion the Gruen movements to 

 the exacting standards of the 

 guild. On Time Hill, Cincinnati, 

 is the American workshop. Here 

 the beautiful hand-wrought cases 

 are made, the movements fitted into them, and 

 then given their final adjustments and tests 

 for accuracy.
