Nicky Henderson's star was unproven on ground so testing and faced arguably his toughest test to date up against Un De Sceaux, Sceau Royal and Saint Calvados.
Saint Calvados and Un De Sceuax made sure there was no hiding place as they set a blistering early pace, but Nico de Boinville was intent to not let them get too far ahead.
With the exception of jumping too big at the open ditch early on, Altior's jumping was at its slickest, although Un De Sceaux made him pull out all the stops.
Turning in it seemed a matter of 'how far' for Altior as he loomed alongside the diminutive Un De Sceaux, but Willie Mullins' nine-time Grade One winner did not go down without a fight.
Altior got in slightly tight to the last, but as he has done in the past, the 8-13 favourite powered up the hill to win going away.
A brilliant finish at @Sandownpark!— Timeform Live (@TimeformLive) December 8, 2018
Un de Sceaux served it up to him, but ALTIOR shows his class and makes it 15 straight victories in the Grade 1 Tingle Creek Chase!
Henderson: "That was special, I think that was really testing him today and, like Buveur D'Air last week, if he was going to get beat it would have been today.
"When you have genuine championship horses it is great people appreciate them, but it does make you feel the pressure.
"They were four very good horses in horrible ground today and they've all run their best."
