6106,6119,6619,etc. These will all drop into the 6105 case, however, you will have to take into account the the quickset date feature of these movements.

6309,6308,6319 can be used however, crown at four position is preferable so date wheel modifications are not an issue. 7548 and 7546 quartz also drop in.

Good luck and let us know what you do!
