What distinguishes it
Look beyond the reference.
Its absence of a calendar suits a clean dial. It keeps the 9015’s 4 Hz rate and 3.90 mm movement height.
For the enthusiast
Compare the 9015 for a date display and the 9075 for a traveller GMT. These are different functions, not a simple quality ladder.
