The Panerai 315 uses a luminescent material called Radiomir. This material was used to paint the numerals and hands on the dial of this incredible timepiece. Panerai opted to use this material that is incredibly luminescent because of its radioactive properties. Panerai has another luminescent material called Luminor, and Panerai uses the name of these luminescent materials to name their timepieces.

This model, Pam 315, is privileged with a tourbillon  The tourbillon was invented by Abraham Louis Breguet in 1795. Most mechanical watches are normally affected by gravity.  Mr. Breguet wanted to find a counter measure for the gravity effect. He rotated the balance wheel of the timepiece to an outstanding 360 degrees and this way the tourbillon was born.

This was a total accomplishment by its creator. He mounted the escapement while the frame rotated itself. This technique is now called the carriage. This rotation helps the movement to have less positional errors.

When the tourbillon was invented most people used pocket watches. Nowadays, the vast majority of tourbillons are found in watches. People normally swing their arms so much every day that it can negate the effect of gravity and makes the tourbillon quite useless. Even with that mentioned, people love watches that includes the tourbillon complication.

This timepiece is privileged with a nice 48mm case and 15mm of thickness. Its case has a nice mixture of angles and curves and is made of a type of titanium that´s fully brushed.

The titanium allows the case to be really light in comparison to its size.

The dial is a “sandwich dial” from Panerai. A sandwich dial means that it´s made of 2 layers that are separated from each other. One layer has a luminous material.

The case back made of sapphire allows seeing the P2005 caliber movement. This caliber combines the gigantic bold plates that are indeed impressive. The power reserve of this beauty is an outstanding 6 day reserve and is only achieved because of the 3 barrels.
