Two used Garmin 310XT watches - both working. Can’t vouch for the battery life but left them running on the windowsill for 5 hours at which point the battery indicator showed 3 of 4 bars remaining i.e. some 50-75% of charge left. Main picture shows both working and locked onto satellites. Variety of watch straps - all Garmin original including twist to remove which would allow it to be placed onto a bike mount (not included). I have set up both for regular straps because the quick release isn’t complete - may be best to buy a new kit but then you can have some spares. Charger included. HR strap - working with new battery. Both watches have been fully reset. No instructions.
