OP XII

About the Panerai OP XII

The 7753 rearranges the 7750's counters to the horizontal axis and moves the date correction to a pusher, and the 7750 piece explains the base's cam-actuated chronograph. Panerai's version runs at 28,800 vph with a 46-hour reserve and 27 jewels at 30 mm across, and it carried the Luminor Chrono and the Luminor Chrono Daylight through the 2000s before the in-house P.9100 arrived in 2013.

In the library it powers 13 Luminor references, most of them Chrono Daylight boutique editions, 7 Ferrari chronographs, 4 Submersibles and 3 Radiomirs. Cases run from 40 mm to 47 mm, with 44 mm and 45 mm the most common. 9 are limited editions.

The OP III is the 7750 with its chronograph removed, the time-only automatic of the same years, and the OP VIII the other Valjoux-based chronograph in the range.
