It is an introduction of Bulova " A17A Cal.10BNCH " in the 1950s .


In 1875 , Joseph Bulova started a jewelry store in the south end of New York under the name of " J Bulova", and then in 1911 , he began to manufacture and sell watches in earnest.

Released the world's first electronic tuning fork clock, the Accutron, which astonished the world with its high accuracy of less than one minute per month.
In addition, it is a brand that has been highly evaluated for its innovative attempts and technical capabilities, such as being adopted for the official watch of the US presidential aircraft Air Force One.


In the 1950s , Bulova delivered many watches that met the US military's mil-spec, and the " A17A " was delivered to the US Air Force at that time.
The lugs on the solid body of machined stainless steel are designed to be thick so that they are hard to damage, giving you a sense of strength.

It comes with an inner case that protects the movement from dust, etc., and is characterized by its military-like characteristic thickness.
The crown is large enough to be easily operated even when wearing gloves, and the back cover is stamped with individual information such as mil-spec.


The dial is based on black, with nicely faded Arabic numerals.
Inside the numerals are the night hours, while the seconds are printed on the outside.

The installed movement is " Cal.10BNCH "
It is said to be Bulova's famous machine, and it is easy to use on a daily basis because it is easy to maintain and has an anti-seismic device installed.
Equipped with a hack function, the second hand stops when the crown is pulled one step.

 Movement is in good condition. The hack function works fine too. The case has some scratches from use.

There is some peeling of the print on the dial, but there is no particular problem with visibility, and rather, it enhances the military-like atmosphere that has survived the harsh environment.


The case size is 35mm (including the crown), which is small, but the size of the crown does not make it feel too small, and it fits perfectly on the wrist.
The simple and sturdy design makes it a great piece for casual occasions regardless of the season.
