Regeneration for the Rolex 1980 Datejust
While the Datejust had been a five-digit reference since the 1970s, the new Rolex Datejust 1980 (Ref. 16200) replaced the Ref. 16000 in 1988. The most incredible innovation of this evolutionary stage was the sapphire crystal that was now used. In addition, the previous calibre 3035 was replaced by the modern 3135 movement. Thus, for the first time, the Rolex 1980 Datejust references had technical features that belonged to the modern era. At the same time, their design was still characterised by the classic cases and bracelets.
Calibre 3135 as one of the best movements in the world
With the calibre 3135, introduced in 1988, Rolex produced one of the most reliable and robust movements ever. This calibre was used until 2008 and was able to stand the test of time for more than 30 years. The resilience and precision of this Rolex 1980 calibre is unrivalled. That is why the in-house movement is rightly nicknamed the "tractor". The 3135 calibre has the following features, among others:
- Date display
- Chronometer certification (COSC)
- Automatic winding
- 28,800 A/h
- Power reserve approx. 48 hours
- Blue parachrom hairspring
