As already stated Bulova uses miota movements which is the movement manufacturing arm of Citizen.
Cheaper lines are made in taiwan if memory serves. Either way solid performers for the $$.
As for them being on par with Swiss ETA I strongly disagree
The Japanese manufacture with disposability in mind, the Swiss do not. I am a Swiss trained Watchmaker and have been at the bench for 27 years.
I have repaired all types and brands of watches as an official repair centre for most. Japanese watches, with few exceptions, are not designed to be serviced. They also discontinue many casing components within 5 years. The Swiss are better about it. Not to say they dont have their faults.
(I worked for Jared as a watchmaker when they had Rolex)
For a few hundred more you can get a Hamilton Khaki Field watch. ETA movement and better after sales support.
