To answer your question, the 473 has…

• Large beveled edges for all of the jewel sinks and bridges; look at where the bridges meet and how each side has a polished bevel. Also the jewels sinks. In short, a higher level of finishing. Such long, continuous polished bevels are rare at this price point, even if done by machine.

• As someone else mentioned, more jewels > less friction on the moving parts

• Addition of a patented power reserve indicator which is more complex to build and rarer than a winding rotor

• The clasp has infinite micro adjust, an innovative feature. The strap has no holes. It’s all done by friction and sliding the strap through the buckle.

• More expensive sustainable deer leather strap.
