You should really take the old layers off  expecially with two layers. 

A. Lange & Sohne has a portfolio of link chronographs that would link be the envy of nearly any other watch brand. In fact, Lange introduced its first in-house chronograph movement – the link Datograph – in 1999, before both Rolex (2000) and Patek Philippe (2005). Vacheron Constantin didn't offer an in-house automatic chronograph until 2016. Audemars Piguet? 2019.

As a result of it being link so common to the point of being boring interest in link vintage Day-Dates have generally lagged Wind says. "In the early link 1970s a Day-Date on bracelet cost about 1200 at the same time an Explorer was about 200. So it was six times the price yet in recent times vintage Explorers were selling for more than an equivalent Day-Date."
