Would-be James Bonds have named their favourite 007 gadget - a watch that can unzip a woman's dress.

　　　The Rolex topped a poll by electrical chain Dixons to mark today's 40th anniversary of the hit spy movies which began with Dr No in 1962.

　　　Invented by gadget guru Q, it was designed to deflect bullets with its powerful electro-magnet.

　　　But the watch--seen in 1973 film Live and Let Die--came in very handy for Roger Moore on his own kind of undie-cover mission.

　　　Second in the survey was Bond's Ericsson mobile phone which remotely-controlled Pierce Brosnan''s BMW in Tomorrow Never Dies, released in 1997.

　　　The pager watch, which spy chief M summoned Sean Connery with in 1963's From Russia With Love, came third while a miniature camera from 1967's On Her Majesty's Service was also named as a fan's dream.

　　　Stuart Carson, marketing director for Dixons, said: "Along with the women, the cars and the exotic locations, gadgets have helped make James Bondsintosa cultural icon."

　　　Later this month, fans of the movies can see a host of 007's gadgets - including the Ericsson phone - at an exhibition which opens at London's Science Museum on October 1.
