I love this watch! I really like how Lu Guang changes colour depending on the light levels :) Needs bright sunlight for full colour change.
I have a small wrist, about 14.5cm around. I like my watch to be able to move a bit, so had it on the second smallest setting.
I'd say the largest wrist it could fit would be about 20cm.
Excellent packaging too.
Didn't take long to have it safely delivered to Australia!
