Quartz oyster perpetual

[Abelf613]

Hello,

I’m new to this forum but have been scouring online and a bit here popped up regarding “prototype” Rolex watches. I’m in possession of a woman’s Rolex watch, black face reading “Rolex Oyster Perpetual, Quartz, Japan Movt. It has diamonds at the 3,6,9, with a continuous gold strap. The movement reads that it is a 9GB00 made by Akita Ltd.
Is this perhaps a prototype during the “Quartz Crisis.” I’m aware that Seiko beat the luxury makers to the punch and they had at one point used their movements before manufacturing their own in 1972.
I can’t seem to find much on any prototypes from that era but this seems like a lot of work to be a fake and given that fakes weren’t even mainstream until the 80’s.
Any advice or opinions are well appreciated!
