Although the Rolex Submariner began its life in 1953 as a sturdy no-frills stainless steel dive watch, today, this famed diver is considered to be one of the world’s greatest luxury watches – while still very capable of plunging into the deep to accompany aquanauts. The Sub’s graduation from utilitarian to upscale no doubt began when Rolex introduced the very first Submariner in solid yellow gold. Nothing says fancy like armor made of shiny precious metal. Let’s find out which reference was the first Rolex Submariner gold watch and lay out the details. When your life depends on a limited tank of oxygen strapped to your back, you are naturally more concerned about the passing minutes rather than what day it is. Which explains why early dive models from the 1950s (Fifty Fathoms, Submariner, Seamaster 300, Breitling Superocean, etc.) didn’t worry about putting a date window on the already limited real estate of the dial. The First Yellow Gold Rolex Submariner Not only did Rolex make the Submariner ref. 1680 in stainless steel, but the company also manufactured a solid yellow gold Submariner 1680. It’s important to note that the first yellow Sub is sometimes simply called the yellow gold Submariner 1680 or the Submariner 1680/8; however, it is not the Submariner 16808 – that’s an entirely different generation. Back to the yellow gold Submariner Date 1680. Rolex’s first gold diver made its debut in 1969, flaunting an 18k yellow gold 40mm Oyster case fitted with a matching 18k yellow gold Oyster bracelet. Early examples of the Submariner ref. 1680/8 featured a rotating bezel with a black aluminum insert and a matching black dial.
The IWC Portuguese Annual Calendar replica is equipped with an Asia IWC 52850 automatic movement, ZF disassembled all 326 components of original movement, after lots of trials of data analysis, the clone movement looks 90% the same as original 52850, besides, its adjusting method and winding feel are 100% the same as original. Because this IWC Portuguese watch has a see-through case back, so on the replica movement, ZF factory needs to work hard on the movement decoration. The following are photos of four Portuguese Annual Calendar watches.
