His side suffered a fourth straight league loss after falling 18-10 at home to champions St Helens.
Huddersfield have invested heavily in their squad since the Great Britain assistant joined from Salford Red Devils last autumn but have yet to see many rewards.
A Challenge Cup victory over Leigh Centurions is their only success but there was no questioning the squad's defensive effort tonight, especially under a barrage of pressure in the first period.
It was remarkable they only trailed 12-0 at half-time but they showed real resolve to find the energy to keep leaders Saints busy after the break.
Chris McQueen and Jermaine McGillvary scored tries and Watson - whose side host Leeds Rhinos on Sunday week before facing Saints again in the Cup quarter-finals - remains confident a win is not far away.
“It will turn; 100 hundred per cent,” he said, having lost 25-24 at Hull KR last week.
“A lot of people lose their heads and try changing things drastically. But it’s not about that.
“It’s about continuity and building things. It can be baby steps in the process. You have to build foundations. It takes time.
“If we turn up with that attitude at Hull KR last time, we win.”
“That first half showed we can handle that amount of pressure thrown at us. Saints really suffocated us. They can do that to teams.
“We take massive amounts from that. We defended really well for large periods.
“I said start afresh second half and we did that. We asked some questions.
"But then it ended up being another tough 20 minutes.”
Saints scored tries via Theo Fages, Mark Percival and Jonny Lomax, Lachlan Coote adding three conversions.
They have won all five games in all competitions and boss Kristian Woolf said: "I’m happy with how we’re travelling along.
"We’ve got a lot of improvement in us. What we’re doing is we’re all willing to work really hard.
"We know that we’re going to get better with the ball.
"I was a bit disappointed with the two tries we let in. We defended for long periods and then let in easy tries in.
"That’s something we need to look at and improve."
