Older Movado. 14k I believe. Anyone recognize?

Picked this up really cheap. Doesn't work with new battery. (6 jewel quartz?)
I do believe outer frame is Gold. Doesn't seem to be a ton of info out there. (Movado Curviplan, Polyplan.)

I think back has been changed, as it does read basemetal steelback on insode, and has number 87-24-467 on back outside.

Just wondering if it's something worth holding, or yank the gold and hope for 18k?
Anyone seen anything like this?|





Thanks in advance!

Pix of inscriptions inside the case back and pix of the exterior of the case back too.

how to buy?

Thanks guys. Will do. Here's exterior back. I'll look for (or take) pics of interior. Back looks to read: 87-24-467. However I'm pretty certain that's not original case back.
