Experience the ultimate companion for your athletic endeavors with the Garmin Forerunner 935 watch. This smartwatch boasts a suite of features including GPS, heart rate monitor and has preloaded profiles for running, cycling, swimming, multipsort/triathlon, hiking, and strength training.  It evaluates VO2 max, training load, recovery time, and training status.  When paired with your compatible smartphone, Forerunner® 935 also gives you access to automatic uploads to Garmin Connect, music controls etc

It has a long-lasting battery life of up to 14 days.

I am no longer using the 935, having purchased a new model.  It still works well and I have noticed the battery life without any use seems to be much longer than 14 days.  When it was in daily use, the battery would last 7-9 days depending on how much it was used to track activities.

I can also include a Garmin HRM which I no longer use- see last photo but it is a bit temperamental and I think it might need a new battery.  Let me know if you do not want me to send this item.  Note:  the item advertised is only relevant for the Garmin 935 and not the HRM.
