Narrative:

Asked to make a crossing restriction 45 southwest of bellaire at FL240. Having only 3 hours in type, I misread the altimeter (drum type). Thought I made restriction but in fact was 900' above that altitude requested. A clear case of being new on the aircraft, a little behind the aircraft, and misreading an unfamiliar altimeter display.
