Rolex Datejust model 16233 with box and papers.
A brief history on the Rolex 16233 compared to the Rolex 16013:
The Rolex Datejust reference 16233 is the upgraded version of the earlier Rolex Datejust reference 16013. The 16233 was now fitted with the scratch resistant sapphire crystal over the earlier models with acrylic crystal. All Rolex 16233 were in stainless steel and 18ct gold as opposed to earlier models which were in either stainless steel and 14ct gold or stainless steel and 18ct gold. Another major difference was the movement. The earlier Rolex 16013 models used the 27 jewelled Rolex calibre 3035 which was introduced in 1977 and had a power reserve of 42 Hours. The Rolex calibre 3135 which was introduced in 1988 now has 31 jewels, still a 42 hour power reserve and and Kif shock absorption. The Kif system is a Rolex invention that make the balance wheel oscillate consistently and accurately.
This is not to say that the earlier Rolex 16013 were not accurate, robust or durable as there are countless Rolex 16013’s the world over on someones wrist right now that, properly maintained will continue to be a highly accurate and reliable watch for many years to come.
