For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
An analog watch. Nothing fancy, just a cheap Casio or Timex or whatever.
An analog watch is the one thing I can’t leave home without.
Ive had the same Timex for about 20 years now. Had to replace the strap a couple times and the battery, but the time keeping works like a charm and keeps perfect time. Mine is the leather strap with a white face and also shows day of the week and date. Not bad for a watch that cost me $20 a lifetime ago.
I do use a smart watch when im exercising though.
