Just glancing around the universe, it seems that any watch that meets the requirements also includes at least some, if not many, of the features for which I have no need. This raises the price considerably, and I'd be paying for a lot of features that I don't want or need.

Let's say I'm on a backpacking trip for a few weeks. I'd likely come off the trail every week or so to stock up on food, but this is where solar charging and battery life come in.

Heartrate is just nice to have. I seem to brush up on my theoretical maximum heart rate in many cases, and while I feel a bit stressed, I don't feel like I'm going to pass out or collapse. So maybe my max heart rate is a bit higher than normal. Still, it's nice to glance at sometimes to put things in perspective. I'm just using online HR calculators, not a real VO2max test.

So what can I buy that has the required features without spending 600 or 700 or 800 USD?

It seems like solar efficiency and long battery life put me into the realm of newer (fancier) watches with features I don't need and higher prices. Technology moves on - I get it. Most people want more of everything, but I just want more of a couple of things. I could ignore the extra features, but the price is the price.

A Fenix 7 Solar (better solar charging, better battery life, better HR monitor) is around 800 USD. And I don't need a sapphire crystal. Suunto and others seem to be in the same range. When dinosaurs rode bicycles I did triathlons I wore some sort of Timex Ironman, but they're a lot different now, and seem to go for less than 100 USD.
