Update, Dec 5th 2023.
I sent an email to Casio, and someone named Paul kindly gave me an answer about this model. Casio W59 was released at the same month as the F91W, in June 1989. The oldest model that's still in production is the CA53 (with an updated module).
Be sure to check out the CASIO W59 and grab one while it lasts!
