Casio is turning the familiar A168 digital watch into a working ring, with silver and gold CRW-002 models listed for November in Japan. The design is the attraction, but the buying decision starts with something less photogenic: whether one of its three effective sizes fits your finger.
This is a miniature timepiece rather than a reason to replace your health-tracking wearable. Its appeal is the small digital display and recognisable watch-shaped face. Before paying for that novelty, separate the product announcement from the rules of the particular shop selling it.
Check the fit before entering
The silver CRW-002 product listing describes an A168-inspired design priced at ¥19,800 including Japanese tax. The gold model's specifications put that version at ¥22,000, also including tax. Those are Japanese prices, not confirmed North American retail prices or landed import costs.
The ring has a 20 mm inner diameter, corresponding to Japanese size 22. Included spacers reduce that to 19 mm or 18 mm, labelled Japanese sizes 19 and 16. Casio says it doesn't provide a size-adjustment service. Treat those as three defined options rather than a continuously adjustable band.
That makes an ordinary sizing check more useful than guessing from a wristwatch you already own. Compare the inner diameter of a well-fitting ring worn on that finger, or get the finger sized before ordering. A gift is harder to buy confidently if you don't know the recipient's size.
The watch functions remain modest and practical: dual time, a stopwatch and a white LED backlight. Casio rates battery life at approximately two years. The time reminder uses a flashing light, so don't assume it will behave like an audible wristwatch alarm.
Japan's lottery is not an international order window
The official Japanese lottery page opens applications on November 2 at 10 a.m. and closes November 6 at noon, Japan time. Results are scheduled for the evening of November 12. Entry is not first-come-first-served, so refreshing at opening time offers no stated advantage.
More importantly for readers overseas, this sale is restricted to residents of Japan. It requires a CASIO ID, and the rules exclude hotel and forwarding-company addresses. Casio also says it won't ship these orders overseas or to forwarding services. This Japanese sale is not an overseas-order route.
If you're eligible, check the fit before entering and follow the purchasing deadline in any winning notification. If you're outside Japan, wait for confirmed local availability rather than treating the Japanese lottery or a yen-to-dollar conversion as an offer you can actually buy.
