For example, movement transmissions are usually this way, and in the traditional Swiss movement, the methodology of direct transmission from the barrel to the balance wheel represents the 'Classic style' of ebauche. However, some companies that make 8 day watches, including Panerai and AP, use a longer mainspring to reach to that specific calculation (8 day that is), that and the fact, that both Panerai and AP use a double barrel transmission system, AP in their 'Millenary' series and Panerai in their L.E.'s A very good post exists in the book 'Theory of Horology' which calculates the exact number of teeth on every specific wheel to be able to count down the hours, minutes and seconds that a watch may require! A very technical post indeed Jp, my congratulations on explaining that like a true pro, Prem Nice explanation indeed!
