### ⭐⭐⭐⭐⭐ Orologio robusto e leggero
*by L***I on 24 March 2025*

Orologio solido e resistente , ma allo stesso tempo leggero , oltre che per me bellissimo esteticamente , la lettura notturna è difficile dati i colori , ma il quadrante è dotato di una micro spia luminosa che si accende con pulsante , anche se con evidenti differenze legate alle funzionalità rispetto agli Smart Watch , la trovo un ottima alternativa , a prezzo ed estetica decisamente più accettabili , e soprattutto senza l angoscia della ricarica quotidiana
