18K case and band
Are you sure that watch has a 10an movement in it ? It's hard to tell much from those pictures but it sure looks like an Accuquartz which would have a 2242 movement.
I'm not going to get involved in naming it, that's not my thing, but that case is rare but that bracelet, Ooh la la !! I've only ever seen one other bracelet like that one. About the only other thing I can tell you is that it was made in Switzerland.
Hi dchavarriae, welcome to myBulova. Beautiful watch you have, I love the 'tuning fork' bracelet. Lyle is correct about the movement, it's very likely that the watch does have an Accuquartz movement, not the 10AN. Is it possible to get a photo of the movement (and maybe a close up on the dial side too)?
Our model designation for this watch should be "Accuquartz".
