Introduced in 2016, this classic Panerai watch has been given the Goldtech treatment: a special alloy of 18k gold that is distinguished by an intense hue, obtained through a higher proportion of copper, and by improved resistance to oxidization, thanks to the inclusion of platinum. It brings wonderful sheen to the sleek lines of the 42mm case, bezel, crown-guard and to the buckle on the interchangeable brown leather strap. This elegance is matched by the white dial, a backdrop for luminescent Arabic numerals, a date window and Panerai's characteristic small seconds at 9 o'Clock. These useful functions are powered by the automatic P.900 calibre. As well as being one of the thinnest movements coming out of the Panerai Manufacture in Neuchâtel, Switzerland, it also delivers a comfortable three days of power reserve.
