I liked being able to order only two batteries because I just don't need a whole bunch of them. I only have one watch that takes this size. I'd rather order them again when I need them. ### ⭐⭐⭐⭐⭐ Delivery speed and good product *by on Reviewed in the United States July 17, 2026* Great product ### ⭐⭐⭐⭐⭐ Worked as it should *by on Reviewed in the United States May 9, 2026* Worked perfectly in my analog digital watch that needed 2 of these to bring it to life.
