When did the steel Daytona get PCL's?

[JPS]

Hi All

When did the steel Daytona first see the introduction of the polished centre links?

I saw a video somewhere on YouTube saying that they had come in around the time of the zenith Daytona's (mid cycle) ? So the zenith's had started off their lives as a fully brushed bracelet before embracing the PCL's? Can someone please confirm this.

Interested to really find out what the thinking was in making the change over to the PCL's on the steel Daytona.

Thanks
