Verdict: These products serve fundamentally different purposes—one is strength equipment and the other a wearable tracker—so direct comparison is limited. The Bowflex SelectTech 552 provides 5-52.5 lb adjustability per RTINGS-style fitness gear tests while the Apple Watch Series 9 delivers 18-hour battery and double-tap gesture per Apple specs and CNET reviews. Neither is a substitute for the other.
Winner: Apple Watch Series 9
Bowflex SelectTech 552: 5.5/10
