Officine Panerai's expansion into the realm of high complications, the P.4100 perpetual calendar calibre, released in 2021, boasts numerous highlights, including adjustable time and dual time zones. This calibre breaks away from the traditional perpetual calendar's complex design by relocating some functions to the case back, resulting in a simpler and easier-to-read dial. Beginning with the PAM00715 watch, the brand has incorporated this calibre into numerous watches across the Luminor and Radiomir collections in just a few years. Panerai's perpetual calendars are no longer limited to Platinumtech™ cases. The introduction of Goldtech™ red gold further enriches the material options for perpetual calendar watches, as exemplified by the PAM00742.
This watch, part of the Luminor 1950 collection, features a cushion-shaped case popular in the 1950s and Panerai's instantly recognizable crown-protecting device, evoking a robust style. At first glance, the 44mm case is crafted from Goldtech™ red gold. Compared to conventional 18K gold, Goldtech™ red gold incorporates additional copper and platinum, enhancing its luster and creating a richer, more vibrant color. Furthermore, thanks to the increased platinum content, Goldtech™ red gold offers enhanced resistance to oxidation and corrosion.
The "sandwich dial" design is a hallmark of Panerai fake luxury watches. This sandwich structure consists of an upper disk with engraved hour markers, a middle layer of luminescent material, and a lower base. The advantage of this design is that it can accommodate more luminescent material, enhancing the luminous effect. This watch features a blue sunray-patterned dial, and the hands and hour markers emit a green glow in dimly lit environments, ensuring clear readability.
The name "Luminor" derives from an early luminescent material. Today, Panerai watches utilize safe, non-radioactive Super-LumiNova®, which offers even greater luminous effects. However, due to the brand's rich heritage, the Luminor name has been retained.
