The Panerai Radiomir Perpetual Calendar GMT is the 45 mm Radiomir Perpetual Calendar, reference PAM01453. Panerai specifies a Goldtech case, automatic P.4100 calibre, three-day power reserve and second-time-zone functions. Its 2024 catalogue says the perpetual calendar corrects itself until 2399; that is Panerai’s stated horizon, not an independently tested result.
What is the Panerai Radiomir Perpetual Calendar GMT?
PAM01453 is the reference number on Panerai’s official product page. The page names the watch “Radiomir Perpetual Calendar”; GMT describes part of its listed functionality rather than appearing in the official product name. Panerai marks it “Boutique Exclusive.”
The watch combines a perpetual calendar with second-time-zone and world-time functions. Panerai’s published specifications describe the movement and features, not independent testing of accuracy, durability or calendar performance.
What does Panerai say about the perpetual calendar?
Panerai’s 2024 catalogue states: “The Panerai Perpetual Calendar automatically corrects itself until 2399, making this calibre eternal.” The year 2399 is the manufacturer’s stated calendar-correction horizon. It should not be read as an independent test result or a claim that the watch will run without maintenance until then.

What functions does the P.4100 provide?
Alongside hours and minutes, Panerai lists the following functions for the P.4100:
- Perpetual calendar, leap year and year
- Day of the week, date and small seconds
- Second time zone, GMT12H and world time
- Power-reserve indication
- Seconds reset and stop balance wheel
The watch therefore has more than a basic second-time-zone display: Panerai explicitly lists both GMT12H and world time as functions. The product information does not explain their operation in detail, so specific setting instructions should not be inferred from the feature list alone.
