A sensor coin the size of a one-rupee coin. Slides under the analog watch you already wear. Heart rate, SpO₂, HRV, sleep — without changing what's on your wrist.
Slide Verge under the watch case. The strap holds it against your skin.
Open the app, tap once. Bluetooth handshake in under five seconds.
Heart rate, SpO₂, HRV, sleep, skin temperature. All in one screen.
Maxim MAX86141-class PPG sensor. The same optical front-end used in clinical pulse oximeters, miniaturised, sampled at 100 Hz against your radial artery.
We build in small runs. Waitlist members get the first slots, founding-batch pricing, and a quarterly engineering letter as we move from prototype to production.
Verge is 30mm wide and 4.8mm thick. It fits under any round-case analog watch with a 36mm+ case diameter. We include a free silicone "saddle" for thin or domed cases. If yours doesn't fit, we refund.
The PPG sensor is a Maxim MAX86141 — the same optical front-end used in many clinical pulse oximeters. In our internal trials against finger-clip ground truth, heart rate stays within ±2 BPM at rest and ±4 BPM during walking. We publish all validation data.
The watch-facing surface is soft PC/ABS with a polished finish. The skin-facing side is medical silicone. No metal-on-metal contact with your case back.
Five to seven days per charge under normal duty-cycled sampling. Charging is a magnetic pogo-pin cradle — fifteen minutes for a full top-up.
Target retail is ₹2,499. Waitlist members get founding-batch pricing, which is meaningfully lower. The exact figure goes out with batch-one invites.
First batch: Q4 2026, India only. International waitlist opens after we clear the first 1,000 units. Waitlist position is honored in order joined.
