It's definitely not for a 33.3 - you can tell immediately because the subdials are closer to the center compared to the 33.3 dials where they are significantly more peripheral.
The value is hurt for this dial because of the condition as pointed out by
@mac_omega but also because it is for the early pre-320 movements and the design is correct only for a small number of chronographs - this dial would be wrong for the vast majority of CH27 and 320 watches.
