Your best option is a Garmin ForeRunner and the USB cable it comes with.
If you’re a stickler about getting the best HRM results then get one with a chest strap but the wrist-based HRM is great for most cases.

- live data at your wrist, streamed to your phone over Bluetooth.
- A chart for the past 4 hours on your wrist.
- Longer charts with zones, averages etc on the app.
- Abnormal heart-rate warning on the watch.
- Export all data via USB to your computer.
Edit: I also got a companion HRM chest-strap (which is more precise and also provides more data related to running), but I only use it for more intense runs/training its not super comfortable.
Yes, it's less accurate than a chest strap, but it works fine for 99.999% of what pretty much anyone wants to do with it. Assuming you don't have mutant wrists, for best results, make sure the strap in snug, but not too snug, against your wrist.
And wrist-based HRM has improved quite a bit in recent years.
