How do you think of the Panerai Lab-ID Luminor 1950 Carbotech 3 Days In 49mm
What is this watch of the Lab-ID Luminor 1950 Carbotech 3 Days in 49mm and how is it ? Well, the Carbotech case measures 49mm in diameter though it's very light and has a matte finish. The sandwich dial has a coating of carbon nanotubes on the dial, which almost entirely absorbs all the light that hits it, making it extremely black. The dial and hands are lit up with blue Super-LumiNova and since you cannot print on the nanotube-coating, the words "Luminor Panerai" and LAB-ID are printed directly on the crystal.
About that dial: there's a material called Vantablack, which has been getting a lot of coverage lately. It's "the blackest substance on earth" and it consists of an array of vertically oriented carbon nanotubes. Vantablack absorbs as much as 99.965% of the radiation that hits it and we're wondering if Panerai has used Vantablack or one of the other available carbon nanotube coatings here. We'll try and confirm and let you know (there are other ultra-black carbon nanotube coatings but Vantablack can be applied at lower temps, making it easier to use than other such coatings). Update: Panerai's informed us that the coating is in fact not Vantablack, but rather a carbon nanotube coating provided by a Swiss partner).
The most impressive thing about the Lab-ID however, is that there are no traditional oils or greases used anywhere in the watch, which is what allows Panerai to offer a 50 year warranty. The new caliber P.3001/C has bridges and mainplates made from a tantalum-based ceramic, which contains a high percentage of carbon making lubrication of the gear train pivots unnecessary. Additionally, the lever and escape wheel are made of DLC-coated silicon, eliminating the need for oil on the escape wheel teeth.
The use of tantalum and carbon containing ceramic also means not only is there no need for oils in the gear train, but there is also no need for traditional ruby jewels. There are only four jewels in the watch: the upper jewel and cap jewel on the upper balance pivot, and the corresponding two on the lower pivot. Usually these jewels have to be oiled exactly correctly but the Lab-ID uses a surface coating of DLC on the bearing surfaces, eliminating the need for traditional oiling.
Lastly, the mainspring barrels (there are two) are also free of traditional oils or greases; instead, Panerai's used a layer of different coatings, including DLC for the top layer. The only other thing we wonder about are the the keyless works for hand setting and winding, but from what we can see of the wheels in question through the caseback, Panerai seems to have done without traditional greases or lubricants there as well.
