The Panerai 2500 movement represents a significant chapter in the brand's history, a robust and reliable automatic caliber powering some of their most sought-after dive watches. This article delves deep into the Panerai 2500, exploring its specifications, its place within the Panerai lineage, and the models it has graced, including the iconic Luminor Submersible 2500m – 47mm, often referenced as PAM 285. We will also address common queries regarding Panerai model numbers, their pricing, and overall reviews.
Understanding the Panerai 2500:
The Panerai 2500 is an automatic mechanical movement, a self-winding caliber developed by Panerai based on the ETA 2892-A2, a highly regarded base movement known for its accuracy and reliability. However, Panerai significantly modified and enhanced the ETA 2892-A2, resulting in a movement far superior in terms of robustness and power reserve. The modifications included increased water resistance, enhancements to the shock absorption, and a higher power reserve. This isn't simply a re-branded ETA; it's a testament to Panerai's commitment to creating movements tailored to their specific needs.
The Panerai 2500 boasts a number of key features:
* Automatic Winding: The movement utilizes an automatic winding system, meaning the mainspring is wound by the natural movement of the wearer's wrist, eliminating the need for manual winding.
* Power Reserve: The Panerai 2500 typically offers a power reserve of approximately 42 hours, ensuring the watch continues to function even if it's not worn for a period of time.
* Jewels: The movement is typically equipped with 21 jewels, which contribute to its smoothness and longevity.
* Frequency: The balance wheel oscillates at a frequency of 28,800 vibrations per hour (4 Hz), a standard for high-quality automatic movements.
* Incabloc Shock Protection: The movement incorporates an Incabloc shock protection system, protecting the delicate components from damage caused by impacts.
The Luminor Submersible 2500m – 47mm (PAM 285): A Case Study
The Luminor Submersible 2500m – 47mm, often referred to as PAM 285, perfectly exemplifies the capabilities of the Panerai 2500 movement. This model represents a classic Panerai design: robust, legible, and undeniably masculine. Its key features include:
* 47mm Brushed Steel Case: The substantial size is a hallmark of Panerai's design philosophy, offering both presence and practicality for professional divers. The brushed steel finish provides a more understated elegance compared to polished steel.
* Unidirectional Rotating Bezel: The bezel, graduated in minutes, is crucial for dive timing. Its unidirectional rotation prevents accidental mistiming, a critical safety feature for divers.
* Water Resistance: The 2500m designation speaks for itself – this watch is built to withstand immense water pressure, making it suitable for professional diving activities.
* Luminor Crown Guard: The iconic crown guard protects the crown from accidental impacts, further contributing to the watch's robustness.
* High-Visibility Luminous Markers: Panerai's commitment to legibility is evident in the high-visibility luminous markers on the dial and hands, ensuring readability even in low-light conditions.
