Cal. PF317 is a dual timezone movement with retrograde date based on Parmigiani Fleurier Cal. 310. It uses a module by Agenhor, Cal. AGH-3502.
The date is displayed using a central pointer on a scale between 2:00 and 10:00 on the main dial. The dual timezone feature uses a second hour and minute hand in a subdial at 12:00 with its own 24 hour day/night indicator pointer at 1:30. The subdial at 6:00 features running seconds and a 24 hour day/night indicator pointer.
