If you don't like wearing watches, you can buy healthy watches. Double Eleven bought a sports health watch for my dad. In addition to the basic motor function, it can continuously monitor the heart rate and fall, which is quite useful.
If your father often wears a watch, you can buy a regular mechanical watch, which is made in Switzerland and has a high grade.
If your dad likes sports, buy an outdoor sports watch like Casio or Songtuo.
Only scoring and purchasing according to demand can meet the requirements.
