A terrific, sexy, original watch.
This is a beautiful watch at a great price. The dark hands on a black face can make it tricky to read in certain conditions, but when that happens (like at night) I tap 'start' once and that switches the display between date and time so I can use the light to see what time it is. Then the next morning I switch back to the date. It's a beautiful watch and at this price it's a steal.

Great G Shock
Great looking G Shock . Digital readout is small and hard to read. The hands cover the readout at certain times making it in usable. Having said that I love this watch. The stealth black out colour scheme looks fab. It’s built to last as you would expect.

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

Ben ürünü alalı yaklaşık 2 yıl oluyor o zamanlar gümrük ve vergi muhabbetleri şimdiki gibi saçma değildi bu yüzden ürünü Türkiye fiyatının yarı fiyatına almıştım. Ürün klasik casio taş gibi başına bir şey gelmezse de ömür boyu götüreceği kesin
