Wyze 47mm charging

I purchased wyze 44mm and 47mm watch and they both came with same charger. I can connect the charger to 44mm watch and it charges but the wyze 47mm watch doesn’t have the same interface as 44mm watch hence I cannot connect the charger. Did I receive wrong charger for 47mm model and how can I charge it ?

Welcome to the Wyze community @ashokjaiswal02!
The chargers for both watches attach to the bottom of the watch with magnets. There’s an indent where the charger will connect.

You may have to try the charger in different directions to connect it.
