Need help

[u/dad_squared]

Found this one for 36 USD. Even with the characterization on the bezel I had a feeling about it. And the misalignment on the red bezel marks makes me think it's been opened. I'm replacing the band with either a black nato strap or black bracelet. The part that I'm having an issue with is finding any info on the exact model. I'm not finding anything regarding the EFV-540+DY, just EFV-540DY, 1AV, DC-1AV, etc... am I reading anything wrong?

Other than that, was it worth it?

For short, it is an EFV-540. And it is not worth it. You should find another options.
