While the new Symphony IV borrows from the iterations that came before it, it debuts an entirely new look for the collection. Up until now, the Symphony line up has always featured stainless steel bar hour markers. This new model utilizes bar hour indexes in conjunction with bold Roman Numerals at the 12, 3, 6 and 9 o’clock. With the new Symphony IV you get the same kind of sophisticated feel, but just with a new design. Dimensions-wise, everything remains unchanged from the Symphony III: 41.6mm across and 11.7mm thick. They even feature the same Orient caliber F6722 movement which can be seen through an exhibition caseback. But this new model features something that the Symphony II did: a scratch-resistant sapphire crystal.
