This picture suggests that the lug to lug length of the IWC is much bigger then the Ventura. The fact is, that the IWC is only 3.5 mm longer then the Ventura. The explanation is that the first links next to the lugs on the IWC have less pivoting. However, you can simply "force" more rotation by carefully pressing down on these first links. Also I think Ventura should have chosen an integrated clasp on the Loga. That diver's clasp with safety lock does in my eyes not match the otherwise smart looks of the Loga.
