Rolex Datejust 3135 Part Job

This Rolex was bought in from a customer in Peterborough. The issue was the time not changing correctly.

After stripping the date mechanism I found a small gear had sheared due to a part seizing up. Would you believe I found all of the missing teeth floating under the dial?

After correcting the first issue, the part was sourced and fitted. Date mechanism reassembled. Its now ticking away, and the time changes lovely!

This was a part job, as a full service wasn't required.

The Rolex Datejust is a classic watch that has been in production since 1945. It was introduced to celebrate the 40th anniversary of the Rolex company, and it quickly became one of their most popular models.

The Datejust was the first watch to feature an automatic date changing mechanism, which was a major innovation at the time. This mechanism was called the "Cyclops" because of the magnifying lens that was placed over the date window to make it easier to read.

The original Datejust had a 36mm case and was made with a variety of materials, including gold, stainless steel, and two-tone combinations. It was also available with a variety of dial colors and styles, including the iconic "fluted" bezel.

Over the years, Rolex has made a number of changes and updates to the Datejust, including increasing the size of the case to 41mm and introducing new materials like ceramic and Everose gold. However, the basic design and functionality of the watch has remained largely unchanged, making it a true classic in the world of horology.

Today, the Rolex Datejust is one of the most recognizable and iconic watches in the world, and it continues to be a popular choice for watch enthusiasts and collectors alike.
