Casio released an interesting addition to their Casioak styled collection which is designed to be worn as a ring. I bought one for myself, and here are my impressions on this timepiece. Musings on the new Casio Ring Watch CRW-001 The CASIO Ring Watch CRW-001 has a retail price of SGD 199 inclusive of GST in Singapore, and is already fully sold out. The CASIO Ring Watch CRW-001 is neither user-friendly nor wearable (for me), but it still makes me smile because it's just so cute to see it worn.
