Review: Saved money and made new - Took my watch to a local repair "specialist" shop. They wanted $50 just to diagnose the problem.

### ⭐ Very low quality battery, dont purchase this.

After correctly installing it, my watch worked fine for about a month. Now the battery can hardly last a full day with the watch on energy save mode. Dont buy this low quality trash.
