Introduction: The Heart of Panerai’s Dive Watches
Panerai has long been recognized for its robust and reliable dive watches, and the Luminor Submersible collection stands as a testament to the brand’s dedication to high-performance timepieces. Among the various elements that define the Panerai Luminor Submersible, the movement (caliber) plays a critical role in determining accuracy, power reserve, and additional complications.

Panerai has developed several in-house movements over the years, and three of the most prominent in the Luminor Submersible line are:
- P.9000 – The foundation of Panerai’s in-house automatic movements.
- P.9010 – A refined version of the P.9000 with improved dimensions and efficiency.
- P.9100 – A chronograph version offering additional functionality.
In this article, we will compare these three key movements, analyzing their specifications, features, and differences to help you understand which one best suits your needs.

P.9000: The Foundation of Panerai’s Modern Movements
Overview
The P.9000 movement was introduced in 2009 and became the backbone of many Panerai Luminor Submersible models. It was developed as part of Panerai’s initiative to produce more in-house movements, moving away from ETA-based calibers.
Technical Specifications
- Type: Automatic
- Jewels: 28
- Power Reserve: 3 days (72 hours)
- Frequency: 28,800 vibrations per hour (4 Hz)
- Functions: Hours, minutes, small seconds, date
- Winding: Bidirectional automatic winding
- Balance Wheel: Glucydur®
- Shock Protection: Incabloc®
Notable Features
- The P.9000 features twin barrels, which allow it to store power for 72 hours, an improvement over standard automatic movements.
- Quick time adjustment feature lets you move the hour hand independently, making it convenient for travelers.
- The bidirectional rotor improves winding efficiency.
- Used in: Several Submersible models, including the PAM00305 and PAM00389.
Limitations
- The thickness of 7.9mm is relatively large, making some watches bulkier.
- Lacks hacking seconds, meaning the second hand does not stop when adjusting the time.

P.9010: A More Refined Evolution
Overview
The P.9010 was introduced in 2016 as the successor to the P.9000. It retained the core features of its predecessor but with a slimmer profile and improved efficiency.
Technical Specifications
- Type: Automatic
- Jewels: 31
- Power Reserve: 3 days (72 hours)
- Frequency: 28,800 vibrations per hour (4 Hz)
- Functions: Hours, minutes, small seconds, date
- Winding: Bidirectional automatic winding
- Balance Wheel: Glucydur® with variable inertia
- Shock Protection: Incabloc®
Key Improvements Over P.9000
Thinner Movement – The P.9010 is 6.0mm thick, compared to the 7.9mm thickness of the P.9000, making Submersible watches more wearable.
Hacking Seconds – Unlike the P.9000, the P.9010 allows precise time-setting as the second hand stops when adjusting the time.
Enhanced Accuracy – Features an upgraded variable inertia balance wheel, improving precision and stability.
Better Winding Efficiency – Features a redesigned automatic winding system that improves efficiency.
Used in: PAM00682, PAM01305, and other modern Submersible models.
Limitations
- While the power reserve remains at 72 hours, it does not surpass its predecessor in this aspect.
- No additional complications beyond basic time and date.

P.9100: Chronograph Excellence
Overview
The P.9100 is a self-winding chronograph movement, designed for Panerai’s Submersible chronographs. Introduced in 2013, it builds upon the P.9000 series but with the addition of a flyback chronograph function.
Technical Specifications
- Type: Automatic
- Jewels: 37
- Power Reserve: 3 days (72 hours)
- Frequency: 28,800 vibrations per hour (4 Hz)
- Functions: Hours, minutes, small seconds, date, flyback chronograph
- Winding: Bidirectional automatic winding
- Balance Wheel: Glucydur® with variable inertia
- Shock Protection: Incabloc®
Key Features
Flyback Chronograph – Unlike standard chronographs, the flyback function allows the user to reset and restart the chronograph with a single press.
Vertical Clutch & Column Wheel – Improves precision and durability compared to cam-actuated chronographs.
Dual Subdials – A running seconds subdial at 9 o’clock and a 12-hour counter at 3 o’clock.
Thicker Movement – At 8.15mm, it is thicker than the P.9000 and P.9010.
Used in: PAM00615, PAM00616, and other Submersible Chronographs.
Limitations
- Increased thickness makes watches bulkier, which may not suit every wrist size.
- The chronograph function adds complexity, making servicing slightly more expensive.

Flyback Chronograph | |||
Improved Accuracy | |||
Used In | PAM00305, PAM00389 | PAM00682, PAM01305 | PAM00615, PAM00616 |
- If you prefer a classic Panerai dive watch with solid performance → P.9000
- If you want a more refined and modern version with better accuracy → P.9010
- If you need a chronograph for diving or sports timing → P.9100
Conclusion: A Movement for Every Enthusiast
Panerai’s Luminor Submersible collection offers a diverse range of movements suited for different needs. Whether you prioritize historical significance (P.9000), improved wearability (P.9010), or additional chronograph functionality (P.9100), each movement represents Panerai’s dedication to craftsmanship and performance.
