ALBION suffered late heartbreak as Watford fought back from 2-0 down to claim a 2-2 draw at The Hawthorns.
Salomon Rondon sent the Baggies on their way before captain Jonny Evans headed a quickfire second swiftly after, both registering their first Premier League goals of the season.
Abdoulaye Doucoure reduced the arrears for the Hornets before the break. But it was Richarlison who was the Watford hero, heading home with practically the last action of the game to earn Marco Silva's side a share of the spoils.
The result, in what was Chris Brunt's 350th appearance for the club, moves Albion up to tenth place in the table on nine points from their opening seven matches.
The home side emerged on to the pitch greeted by the atmosphere of Diversity Day as the club celebrated its equality, togetherness and unity.
And it was Albion who found themselves 2-0 ahead inside the 21st minute courtesy of two swift goals.
Firstly, Grzegorz Krychowiak sent a superb long ball over the Hornets defence from which Rondon showed great strength to hold off Christian Kabasele and beat Heurelho Gomes from a tight angle at his near post.
Just three minutes later the hosts doubled their lead, Evans bravely heading home from close range after Doucoure had inadvertently flicked on Matt Phillips' inswinging corner.
Ahmed Hegazi spurned a great chance to nod home a third from Brunt's corner, before Andre Carrillo wasted an even better headed opportunity at the other end.
And it was the visitors who struck next to halve Albion's advantage before the break, Doucoure firing low across Ben Foster, via a slight deflection off Evans, having been fed by Richarlison.
Gareth Barry deflected Etienne Capoue's drilled effort narrowly wide early in the second half as the Hornets looked to draw level.
Richarlison then headed wide as Albion held strong and, having turned to James McClean, Jake Livermore and Hal Robson-Kanu off the bench, the former tested Gomes with a strike from distance.
McClean saw a fizzing half-volley deflected wide in added time but then gave away a seemingly harsh free kick with just seconds remaining on the clock.
And Richarlison was on hand to nod past Foster and earn his side a valuable point.
ALBION: Foster, Dawson, Hegazi, Evans (c), Gibbs, Phillips (McClean 57), Barry, Krychowiak, Brunt (Livermore 62), Rodriguez, Rondon (Robson-Kanu 73).
