get the Apple Watch Ultra 2 if your wrists can fit it comfortably. It may be as old as the S9 but trust me it will still stay supported for the next years to come. It will also be the best idea if you tend to charge your Apple Watch every few days thanks to its 2/3 days battery life. Definitely please make a trip to the Apple Store on your day off; there are helpful Specialists who also wear an Apple Watch for a while already and they can help you try on the bands and show you how to put them on. If you get the Solo loops you can get fitted for them as well; the Apple Store has a paper measuring tape that gives you the number size that you need.
If you are worried about blood oxygen sensor is not working on the new Ultra 2 due to patent disputes with Apple then there are still Apple Watch Ultra in natural titanium that has blood oxygen sensor working fine in watchOS 11. Get the 1st generation Ultra or the launch day 2023 year Apple Watch Ultra 2 as these models still have blood oxygen and you can also still get a great deal out of it when you buy it in Walmart, target or Amazon.
