A pensioner had a watch stolen from his wrist by robbers who broke into his home in Gerrards Cross.
Two men smashed rear patio doors on a property in Dukes Wood Avenue at 12.10am on Sunday, May 7.
The occupant, a man in his seventies, was attacked by the men and had his watch stolen.
They then fled the scene, possibly on a motorbike.
The pensioner suffered bruising to his arm and a cut on his wrist but he did not require hospital treatment.
The offenders were both black in their late twenties, about 6ft and were wearing black clothes.
One, or possibly both of the men were wearing the hoods up on their jackets.
Investigating officer, PC Louise Snodgrass, based at Taplow Local CID, said: “I would like to hear from anyone who witnessed this incident or who has any information which relates to it, to please contact us.
“If you have any information which you think could help our investigation, please contact the Thames Valley Police non-emergency number on 101.”
