Greetings Ebo109, thank you for reaching out with your question about the Samsung Galaxy Watch7. That's a great question! Yes, the advertised Watch7 can monitor your blood pressure. Before your first use, you must calibrate the watch using a standard, cuff-based blood pressure monitor. You will take three baseline readings with the cuff and enter them into the Samsung Health Monitor app on your paired Galaxy phone. The watch uses its light sensors to monitor the changes in blood flow through your wrist. By analyzing the time it takes for the pulse wave to travel from your heart to your wrist (pulse transit time) and comparing it to your calibrated baseline, it estimates your systolic and diastolic pressure. To maintain accuracy, you must recalibrate the watch using a standard arm cuff every 28 to 30 days. Note: The Galaxy Watch is a wellness tool, not a certified medical device for diagnostics, and cannot replace traditional clinical monitors. The feature also requires a compatible Samsung Galaxy smartphone to set up and function. Please feel free to reach out to Support if you have additional questions. Thank you for being an integral part of the Galaxy ecosystem! - Debra
