Ever since the Apple Watch Series 4 in 2018, the larger-sized aluminum Apple Watch has started at $429 in the U.S., but that has changed with the Apple Watch Series 12. While the Apple Watch Series 12 with a 42mm case maintains a starting price of $399, the 46mm model has received a $20 price increase and now starts at $449. In other words, stepping up to a 46mm case now costs an extra $50 instead of $30. Apple products are getting more expensive lately.
