Probably use a modern watch, it will provide the information you need and with the headphones (wireless or not) you can answer phone calls, get your texts read, etc.

If you're running I would recommend a Garmin device. Its the Professional class of device to help you keep your heart rate and progress. Anything else is just a gadget compared to Garmin.

For runners check the Forerunner line of watches, for my workout style (anything that makes me move) I chose the Fenix watch.

Good for you that you're exercising!
