A SILVER watch could hold the key to identifying a human skeleton discovered by a mother and her teenage son during a morning walk near Sydney.
The woman and 13-year-old boy were walking on a bush track at Sandy Bay when they made the grisly discovery last week.
The shocked pair walked to a nearby fish shop and phoned police.
At first officers were unable to find the site but a search team retrieved the skeleton over the weekend.
A crime scene has been established and forensic teams are examining the bones.
The only clue police have so far is a silver Citizen-brand wrist-watch found with the remains.
Police released two images of the watch on Thursday.
Detective Inspector Ian Mitchell told reporters in Sydney it was "too early to make assumptions" as to the cause of death but he hoped someone with a missing loved one would recognise the watch and get the closure they deserve.
Anyone with information can phone Crime Stoppers on 1800 333 000.
