Hello bulova community,
I recently acquired this watch and have a few questions. I am not able to open the case at the moment.
The back case has the following text: BULOVA N4 H877545 STAINLESS STEEL CASE WATER RESISTANT.
The wristband says Speidel USA.
1) Does it look authentic?
2) Model number? I've see similar ones that mention 218, 2181 and 2182 but am not sure if that's related to model numbers.
3) Is the Speidel wristband possibly the original one that came with this watch? I've seen other similar bulovas with a Speidel band so not sure.
4) What battery is recommended?
Thank you.
Looks to be a match for a 1974 Bulova Accutron Calendar "DF"

Thank you! Do you know of a recommended battery for this watch?
The movement should be a 218D which will take a '344'.
Make sure to insert the battery the correct way up.

Thanks for the confirmation.
Yes - 1974 Bulova Accutron Calendar DF is good for ID. As you can see from the line book entry above it originally came on a lizard (leather) strap. The Speidel band is not original to your watch.
