What the differences mean
At the 7-iron, the 690.CB is 35° and the 731.PM is 33°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the 731.PM should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the 690.CB. Across the 9 clubs both sets share, the 731.PM averages 1.4° stronger, with the largest gap at the 6-iron (31° vs 29°). The pitching wedges are 47° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the 690.CB 7-iron sits 1.5° flatter (61.5° vs 63°), which nudges start direction slightly right for a right-hander; the 731.PM 7-iron is 0.25 inches longer (36.75" vs 37").
The sets are built differently: the 690.CB runs 2-iron to W (10 clubs), the 731.PM 2-iron to PW (9 clubs).
The 690.CB is a players iron and the 731.PM a blade iron, so they sit one step apart on the forgiveness scale. The 690.CB is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly scratch to 10 handicaps. The 731.PM trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.
The 690.CB is listed as forged cavity back and the 731.PM as investment cast blended set - cavity back long irons, muscle cavity mid irons, muscleback short irons. Forging, as in the 690.CB, is generally credited with a softer feel; casting, as in the 731.PM, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons. The 731.PM's muscle-back shape keeps mass directly behind the strike for feedback and control, where a cavity spreads it to the perimeter for forgiveness.
Both sets were introduced in 2002, so this is a choice between two models from the same lineup rather than an upgrade: Titleist designed them to sit side by side for different players.
Which should you choose?
The 731.PM is the stronger-lofted set — up to 2° stronger than the 690.CB on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Do the Titleist 690.CB and 731.PM have the same lie and length?
Not exactly. At the 7-iron the Titleist 690.CB is 61.5° lie and 36.75 inches, the 731.PM 63° and 37 inches. Both can be bent or built to your own fit.
