The dial of this Extra Plat starts as a dial blank of solid 5N rose gold, then is engine-turned by hand on a rose lathe to achieve the guillochage on the various sections of the dial in recognizably Daniel Roth style. Afterward, all the markings—Roman numerals, the Daniel Roth logo, dial number, etc.—are pad-printed with a pink varnish to protect them during the subsequent electroplating treatments. After the varnish is demasked, all the dial markings reveal the underlying layer of gold. Paired with a 5N rose gold case, in a very compact 38.6mm diameter and (as demonstrated by the name) very slender 7.7mm thickness, the final result is a gorgeous black-dialed dress watch with just that extra bit of detailing for the owner to appreciate.
