For what its worth, my personal and very comfortable Crewsaver is about 10 years old, but failed to hold its pressure for more than a few minutes when I decided to replace the whole Hanmer auto inflate a month ago!
Are you sure the new Hammar unit was properly reseated in its hole? It's quite common to get it slightly misaligned, resulting in a leak at about the rate you describe. Would be unfortunate if you binned a good jacket if that was the cause; if so, taking the inflator out and putting it back in correctly would have sealed it.
This also shows the importance of doing the inflation test after changing any parts (as you did), not before!
