Hi Dan,
yes, absolutely correct time frame. Gruen filed for protection of these movements in May 1908, but it is known that movements from this filing have been produced in 1905 already.
Here the picture of the cal. 45 from that filing:
This is a Madretsch movement and since 1903 Alfred Aeby ran the Gruen Manufacturing Co. in Madretsch. So it is very likely that the Matretsch production came from the Aeby facility. As Aeby left the Gruen Manufacturing Co. in 1909 and Ernest Degoumois in St. Imier took over this movement was produced between 1905 and 1909.
I find the 125k offset of front and back serials very interesting. Could it be that the first Madretsch movement would be serial # 125001?
