Is the Huawei Watch GT 7 Pro worth £100 more than the standard GT 7?

Only if the titanium and ceramic case matters to you over years of wear, or if you need the 40-metre freedive rating. Every software feature, battery life at matching case size, and sensor beyond ECG and depth are identical between the two.

Should I buy the GT 7 Pro for its ECG sensor?

No. The ECG is on-demand only, meaning it captures a reading only when you actively check it. Arrhythmias are often intermittent and asymptomatic, so an on-demand sensor is poorly suited to catching problems you don’t already suspect.

Does the standard Huawei Watch GT 7 support diving?

No. Only the GT 7 Pro carries a 40-metre freedive rating. Both watches handle swimming and general water exposure without issue.

Is battery life better on the GT 7 Pro?

Battery life tracks case size, not tier. The Pro’s 45.6mm case and the GT 7’s 46mm size both reach 51 hours of continuous GPS in trail running mode. The GT 7’s smaller 41mm size manages 32 hours.
