A smart watch (1), a method and a system for measuring blood glucose therethrough, wherein the method for measuring blood glucose comprises: turning on blood glucose measurement module (300) by obtianing a signal for turning on the blood glucose measurement module (300) through test strip inserting detection module (400), the blood glucose measurement module (300), after turn-on, generating a turn-on signal for watch operating system module (200) to turn on the watch operating system module (200) measuring the blood glucose content of the tested blood on the test strip and displaying the measurement result through the watch operating system module (200), the watch operating system module (200) uploading synchronously the measurement result to a server obtaining a signal of ending the test and generating an alert signal for pulling out the test strip after the test strip is pulled out, generating a signal for turning off the blood glucose measurement module (300) through the test strip inserting detection module (400) to turn off the blood glucose measurement module (300), the blood glucose measurement module (300) generating a return signal to make the watch operating system module (200) return to the main interface. The smart watch (1) has a function of measuring blood glucose, thereby facilitating the measurement of blood glucose, the measured data are more accurate, and the measurement result is uploaded to the server and is convenient for viewing.Linvention concerne une montre intelligente (1), un procédé et un système pour mesurer la glycémie par lintermédiaire de cette dernière, le procédé pour mesurer la glycémie consistant à : mettre sous tension un module de mesure de glycémie (300) en obtenant un signal pour mettre sous tension le module de mesure de glycémie (300) par lintermédiaire dun module de détection dinsertion de bande de test (400), le module de mesure de glycémie (300), après mise sous tension, générant un signal de mise sous tension pour un modu
