Rolex Daytona Calibre 4130

After my second Daytona I realized that the 4130 movement came into being in the year 2000. It has a 70 to 72 hour power reserve. The question is why has it taken so long for other movements to attain this? Why not 18 years ago?

The 4130 was also the first movement to get the Parachrom hairspring. It was designed ground-up to have as few of parts as possible, giving way for a larger barrel and mainspring. They designed it to be the smallest, most reliable, technically advanced, in-house automatic chronograph available. And, arguably, it still is.

18 years ago, a 48-hour reserve was plenty for most. Now buyers seem to care more about movements. I can only suspect that Rolex finally felt pressure to up their game across the line. The 5-year warranty and 70~72 hour reserve puts them ahead of many on the mechanical end and more inline with the asking price.

But, the 6-digit Daytona certainly paved the way.

I agree, nice video; I'd say almost two decades is a bit long to roll out new technology!! Also interesting is the list of comments following the video; many Rolex haters!
