Arma Bianca will sell special Q&Q SmileSolar watches with collaboration designs from the Persona series. The brand revealed three models based on the protagonists of the popular games Persona 3, Persona 4, and Persona 5. The only differences between the three models are the external designs. The blue Persona 3 watch has “Special Extracurricular Execute Sector” written on its side strap with an Evoker icon on the free loop. The yellow Persona 4 model instead has “I’m yourself, you’re myself” with a Glasses icon, while the red Persona 5 one has “Take Your Heart” and Joker’s mask. All three Persona watches will come with a solar-powered battery that lasts for around 3.5 months after fully charged. They will also have 10-bar water resistance and polyurethane straps that won’t easily get sticky or uncomfortable due to moisture.
