Explorer 40

No bezel, no date, no second time zone — the 40mm Explorer is the reference I use internally as a baseline for the legibility axis, because there's nothing on the dial competing with the hands. This 224270-0001 is steel, black dial, $9,115, rated to 100m, and it sits in size right between the smaller Explorer and the bulkier Explorer II. Of the three, it's the one most people should try on first — it reads clean at a glance in a way even good divers and chronographs rarely manage once you load them with subdials and inserts.
