How to identify this generation
- APEX lettering runs along the top bar, with a Callaway chevron logo low on the toe side and TUNGSTEN near the heel.
- Callaway reuses family names across years (Apex, Big Bertha, Rogue, X Forged), so match the year-specific markings and photo as well as the lofts.
What to notice in the specifications
- Callaway’s live site no longer serves this data to automated requests; the figures come from an Internet Archive capture of Callaway’s US specification panel dated 2021-11-08.
