Circular Ring 2 (model CR2) vs Vital Signals Signal Ring

Buyers who want a titanium ring with an ECG sensor, paid for once with no required subscription, in a choice of four finishes from $349, and who are willing to order the $5 sizing kit and wait for it before the ring ships.

You lift weights or carry heavy loads with a ring on; you want to wear it in a sauna or in the sea; you expect contactless payments, which the Ring 2 specification does not list; you need one settled battery or charge time figure before buying; or you would rather wait for Ring 3 pre-orders in December 2026.

Buyers who want passive pulse and blood pressure trend data in a ring, pay once with no membership, and are comfortable pre-ordering ahead of an October 2026 ship date.

You want sleep, HRV, and readiness in the same ring, since the brand says those are not here yet, or you want published accuracy validation before you buy, since Vital Signals publishes none. Also skip if you ship outside the United States.
