During the 16-year production period, Ref.116520 has undergone several revisions, including the design of the bezel, the thickness of the hands, the luminous material, the buckle style, etc. We list most of the revision content and time for you.
Major revision of Ref.116520
- 2002: The tachymeter mark on the bezel was changed from engraving to printing, mainly reflected in the thicker font.
- 2004: Hands (minutes and seconds) thicker
- 2006: The letters “ROLEX” are engraved on the inner ring (the inner wall around the dial), and the watch’s serial number is placed at 6 o’clock.
- 2007: Rolex’s unique blue hairspring with excellent anti-magnetic and anti-seismic properties was adopted for the first time.
- Ref. 116520 was the first model to use a Parachrome hairspring from its release date, but it was not blue then.
- 2008: Changed the buckle style.
- 2010: The 27-second and 33-second positions of the second scale used for the chronograph function are circulated. This feature is common in products made between 2000 to 2005, and those made from 2006 to 2009 are primarily short.
- (Especially a feature commonly found on black disks.)
- 2010: The color of the chronograph counters of the black dial changes from silver mixed with light yellow to pure silver.
- 2011: The color of the chronograph counters of the white dial changes from silver mixed with light yellow to pure silver.
- The silver chronograph dial mixed with light yellow is still there.
- Around 2012: Buckle style changes
- 2013: The luminous paint was changed from Super-LumiNova to chromite, and the bright color was changed from green to blue.
- Mid-2015: Buckle mid-panel changed from matte to mirrored.
Among the many revisions, the most popular is Ref. 116520, which combines the garbled serial number and mirror clasp. As shown in the picture below, this combination is the final form of this watch. It was discontinued after less than a year of production, and there are very few surviving products, so many Rolex lovers are flocking to it. Richard mille replica.
