Front Dial Back Back Mark Cuvette Cuvette Mark Movement View 1 Movement View 2 This split second chronograph with register is an example of the top of the line work carried out by many Swiss makers of the early 20th century. This example has been neglected by a previous owner and not yet cleaned and restored. I don't know if this Guillaume has any relationship to the Guillaume who invented temperature invariant alloys and the Guillaume balance. Many chronographs show up with Piguet and Meylan, but this is the first Piguet and Guillaume I have seen. |
