Diamond Like Carbon coating

The GC20-DLC-00
Original Time

The Maestro Original Time ref. GC20-DLC-00 undergoes a complex coating process with Diamond Like Carbon, known by the acronym of DLC. Similar DLC treatments are applied in high-end engineering to drastically improve performance and durability of supersport motorcycles or Formula 1 racecars.

The value of such coating accrues from its unique ability to provide some of the properties of diamond to the stainless steel, Maestro case, surface. Improved hardness, reduced friction and wear resistance are three main achievements of Gerald Charles DLC coating. This exclusive treatment is performed at no compromise, 100% in Switzerland, with state-of-the-art technology and machinery.
