Bulova 1935 American Eagle
The tonneau shaped CASE measures 35mm lug tip to tip and 24mm excluding the crown. The case serial number is stamped to the outside of the case which causes me some concern about its manufacture date.
The DIAL is matt silver and is funished with radium stylee numerals and a black printed inner minute track and sub seconds dial almost obliterating the 6.
There is no dust shield which suggeststo me that the movement could be towards the end of its run.
