Police are investigating an aggravated burglary in a village near Coventry.
It happened on Wednesday (7 November) night at around 10.40pm at a house in Leicester Road, Shilton.
Three offenders forced entry to the house and attacked the occupant with hammers before stealing a watch.
They fled the scene in a dark coloured saloon car - possibly a BMW 3 Series - which was parked in Bulkington Road. They drove off in the direction of Bulkington or Coventry.
The victim suffered injuries to his arm and knee.
Detective Constable Tom Willett said: "We believed this was a pre-planned attack and the offenders showed no hesitation in using violence against an innocent homeowner.
"We're keen to speak to anyone who was in the area between 10pm and 11pm, especially if they have dash cam footage.
"We're also keen to speak to the driver of a gold car who was driving on Bulkington Road around the time of the offence and may have been overtaken at speed by the offenders.
"The watch is a distinctive Audemars Piguet Royal Oak Offshore. If anyone sees one of these watches for sale I would urge them to contact police."
