The fake rolex Submariner umpire 16610 had a long run from 1989 until 2010. During that time, as you would expect, China will undergo a series of changes and modernizations. In addition to the new hairspring, the lume type used in the index has changed three times. 
For the first 10 years, rolex still used tritium, which was much safer than radium used in the 1950s and 1960s; However, it is actually radioactive. This type of dial is on the bottom edge, below six o ‘clock, marked “T Swiss T” or “swiss-t <25”. Then, Rolex briefly switched to a substance called LumiNova, a completely nonradioactive light-emitting paint. The dials were made between 1998 and 2000 and simply read “Switzerland”. Finally, starting around 2000 and continuing until the end of production at no. 16610, Rolex replaced the luminous material again, this time with the super luminous material. Almost identical to the photoluminescent material about to be emitted, you can identify these models with the words “made in Switzerland” at the bottom of the dial.
Around 2007, Rolex also began engraving its name and the watch’s serial number on the inner ring around the dial, called the rehaut. The move is an attempt to try and thwart the counterfeiting that has long plagued Rolex, especially the Submariner pilot, which is believed to have the highest counterfeiting rate of any watch. In addition, the engraving of the watch’s inner ring also helps protect the watch’s important serial number from wear and difficulty in reading, which sometimes occurs when it is placed between the ears at 6 o ‘clock on the case.
The bracelet has also undergone some improvements. Only the classic three-chain oyster bracelet (much like the brand’s other fake rolex watches in the “pro” line) will be released, and from around 2000 onwards, it will be given a strong chain tail link. Prior to this, the end connections were separated from the rest of the bracelet and were sacred in design, and their primary purpose was to fill in the gaps between the lugs, not as structural parts of the bracelet. However, the completely reliable bracelet link and Glidelock extension system did not appear on ref. 16610, and it was not until the current model was released that the Rolex Submariner had today’s bracelet style.
Finally, the Rolex Submariner 16610 still had ear holes until 2003. Although the small holes near the ears led to a slightly less elaborate, more tool-like appearance, they are now one of those little details that collectors love today. In addition, they are also a feature that makes switching bands and changing bands significantly easier.
Overall, the Rolex Submariner judge 16610 is often considered the best last. The replica watch has lost modern elements such as a ceramic bezel, but it has regained classic styling elements and a more elegant silhouette. Most importantly, it is powered by the longest and most combat-ready movement in Rolex history, and the watch itself is forged from an almost bulletproof stainless steel. Simple yet classic styling has proven to be truly timeless; Whether paired with a business suit or a wetsuit, a Rolex Submariner can go with anything.
