In the vintage Rolex world, the term tropical points out that the dial has discoloured due to chemical reactions caused by external factors such as sunlight. This is a very desirable, therefore, highly collectible and precious feature.

The 'tropicalization' process takes many years as the sun’s UV rays slowly degrade the lacquer and paint used on older dials. A nicely faded dial can add warmth and charm to a vintage watch. On this watch, the dial has taken on a rich and vibrant brown color; from dark chocolate-brown on the outer edges–especially on the right side–to a light, creamy, toffee color in the center. This offers a wide variety of mesmerizing shades and colors when the watch is exposed to sunlight. Another distinct and beloved feature of this reference is the nipple dial: small protruding hour markers made from gold that have earned the moniker 'nipple index' because... Well, you get the point.

This beauty dates back to 1978 and runs on the calibre 1575 automatic movement. The 18k yellow gold case is in wonderful condition with thick lugs, sharp edges and a rare and tight 18k yellow-gold riveted Oyster bracelet. The rotating bezel features an anodized aluminium inlay in a beautiful warm brown color.

The 1675 GMT-Master is the quintessential vintage pilot’s watch and with this 18k yellow gold beauty you’ll be the flyest pilot in the sky.
