Yesterday we showed you the first chronograph Patek Philippe introduced in almost forty years, 1998’s Reference 5070.  This was a big deal for chronograph collectors, but one year later, the 5070 would meet stiff competition from an unlikely source – Glashutte, Germany.  A. Lange & Sohne was but a few years old in 1999, but the Datograph was to become a veritable benchmark in haute horology architecture and finishing.  It was a column-wheel chronograph with a fly back mechanism and a big date, and what was most impressive, is that the Datograph was completely in-house, one of the first of its kind. 

The Datograph sent shock waves through the finest manufactures in the Vallee de Joux, inspiring the trend of in-house chronograph movements that we are still seeing today. The 1999 ALS Datograph remained untouched, with a platinum case and black dial for twelve years, until last month’s announcement of the new, larger Datograph UP/DOWN.

And now you know the rest of the story.
