Amongst the collectors of rare vintage timepieces, watches that feature the so-called "tropical dials" are particularly highly sought after. The dials – mostly originally black – have faded over the years from black to brown or, such as this dial, developed gold dapples that bestow the watch with a new and unusual beauty.
