Series 7 is 100% worth the 100 bucks, a nicer looking screen, on screen keyboard and 1 more year of software update. And in your case, the bands are a welcome bonus.

You should go ahead with the Series 5. Most likely the Series 6 won’t bring any significant changes to the Apple Watch. This is because Apple uses a three-year design cycle for the Apple Watch. We’ve seen the same design used over Series 1 through 3. Apple only updated the design for Series 4. With Series 5, we only got the always-on display and other minor updates. New Design vs Old Design The main rumored feature that Series 6 will bring is sleep tracking. Other features will be better battery life and maybe a new microLED screen technology. So unless you are really looking forward to the sleep tracking feature, you should be fine with Series 5.
