The High-tech Ceramic on Panerai Tuttonero Luminor GMT

Panerai introduced the Tuttonero Luminor 1950 3 Days GMT Automatic 44 mm. Its Paneristi-friendly reference number is PAM01438. In Italy, “Tuttonero” means “all black,” so it made the perfect nickname for this new model from Panerai, a brand with a strong Florentine heritage.

With a Luminor case and the Panerai bracelet in ceramics, Tuttonero is made entirely of matt black ceramic: a watch with extraordinary aesthetic impact, which is faithful to the Panerai identity and constructed using the most advanced technologies in materials.

The bracelet is also made entirely of matt black ceramic, the design results from lengthy research aimed at achieving perfect integration with the ceramic case. The highlight of this watch is the unusual ceramic material that they use in this watch.

Panerai uses a high-tech ceramic made of zirconium oxide (ZrO2). The material is made from powder which is isostatically pressed while the final shapes of the various components are formed by the grinding process.

This high-tech ceramic has many qualities: extreme hardness (up to five times greater than stainless steel), resistance to scratches and shocks, and its surface has a very high aesthetic impact. The black dial comes with luminous Arabic numeral and has central hour and minute hands, the small second dial at 9 o’clock and the date at 3 o’clock.

This watch is powered by the automatic P.9010 calibre that was entirely developed and created in the Panerai Manufacture in Neuchâtel. The energy of this movement is necessary to accumulate a power reserve of three days, the basic standard for Panerai in-house movements. The power is stored in two spring barrels whose springs are wound by an oscillating weight operating in both directions.

The Tuttonero Luminor GMT comprises 200 components including 31 jewels, the calibre has a diameter of 13¾ lignes and it is 6 mm thick. The balance, fixed by a bridge with twin supports, oscillates at a frequency of 28,800 vibrations per hour (4 Hz). It is associated with the device which stops it as soon as the winding crown is pulled out, enabling the watch to be perfectly synchronised with a reference signal.

In the P.9010 calibre, the hours can be conveniently adjusted without interfering with the movement of the minute hand, thanks to the device which directly moves only the relative hand in jumps of one hour forward or backwards.

This function is very useful when changing time zones or moving between summer and winter time, and the adjustment of the hour hand is automatically connected to the date indicator.
