Unless I just don't really understand how Tourbillons work I am struggling to see why they would perform the same function yet consist of a different number of parts and yet still weigh the same. I do understand that a Tourbillon is a mechanism that rotates the escapement and balance wheel within a cage and that this rotation helps counteract the effects of gravity on the timekeeping components and potentially improving time keeping. Sorry for being a pain but I noticed a visible difference between the two watches and then re read the post to garner the information as to the differences between them. I acknowledge they differ I just can't understand why.
