found, or finding out, this is very true, indeed. I wonder if they do this intentionally to drive us amateur hobbyists nuts? Same with their movement numbers, model numbers, and every other number combination they can think of...

Probably NOT intentionally :-).

Be aware of possibly cataloguing errors also. I ordered one part - received.. something similar, but not what I ordered. Had to send them photos and diagrams and ask for the right part to be shipped. They agreed there was cataloguing error and refunded my money, but stated that the part i was looking for has been discontinued. Sad, eh? This is not the end of the story as I cross-referenced Bulova to Buren and ordered Buren part for Bulova (identical movement). Funny, but they had plenty of Buren parts, which are perfect fit for Bulova. Happy end!
