I'm looking into buying a new freediving watch. It's intended for freediving only. Therefore, scuba diving capabilties don't matter, and I'd rather not Pay an extra to have them included. At the moment, I'm looking more closely at Suunto D4f, Omer UP-X1 and Mares Smart Apnea. I'd like to know more about their specific advantages and disadvantages. Can you help me?

For example, the Omer watch is the only one with a heart rate monitor. However, I haven't found any positive review on that feature. How good or bad does it work in practice?
