The Hornets suffered their second away defeat in succession on Saturday, going down 1-0 to Crystal Palace in a scrappy game at Selhurst Park.
Troy Deeney's second-half own-goal was the difference in a quality-shy affair befitting of the two clubs' league positions.
Walter Mazzarri's side did little to trouble the Eagles' defence over 90 minutes. Tellingly, Mamadou Sakho gave Deeney perhaps his most difficult afternoon of the season, dominating the aerial battle.
Sam Allardyce praised the "mental toughness" of his back-line during his post-match press conference, and he wasn't wrong - they barely made a mistake all afternoon and spared the blushes of their teammates at the other end of the pitch.
Watford's best flashes came from distance - Etienne Capoue, Valon Behrami and Abdoulaye Doucoure all tried their luck in the absence of real opportunities closer to Wayne Hennesey's goal.
Another break in Premier League action now then, two weeks for the Golden Boys to prepare ahead of crucial hostings of Sunderland and West Bromwich Albion in early April.
