My brother has one too and he doesn’t wear it (I think he wears a Casio most of the time). Asked him if he wants to sell it but he said said maybe later this year. 🤷🏻♂️
It has xx/50 engraved on the back
It’s like a cobalt blue
GP would do well to come out with cushion cases again. It’s been 20 years since …
