We all know Ferdinand Adolph Lange developed the signature three quarter plate which is characteristic of most of their timepieces. But how many of us have the opportunity to learn the history of the three quarter plate?
The good people of Lange & Sohne invited us for an event at their boutique at Ion Orchard. Presenting the session was Miss Joanna Lange, Technical & Sales Trainer at Lange, Chris Leung from Lange Hong Kong and Miss Michelle Chen, Head of Lange Singapore.
Joanna brought us through the evolution of the three quarter plate, explaining firstly that the four examples that they brought in to Singapore is the first time these four pocket watches have been taken out from the Lange Museum in Glashutte. The first pocket watches were made by Gutkaes and Lange - Gutkaes being the master of Ferdinand Adolph Lange. Between 1845 to 1855, all pocket watches came with what they classified as triangular plates.
The front dial is enamel but no signature - just a plain dial.
After the triangular plate, Ferdinand Adolph Lange developed the half plate which he found to be more stable than the triangular plate. Unfortunately, they did not have an example with them. But I was informed by Joanna that the half plate were for watches made between 1855 to 1860. Then came the two thirds plate.
Many thanks to the folks at Lange & Sohne for a wonderfully educational evening. It also gives me a different perspective on the piece I own. Here's my blog on my Lange pocket watch. I would also like to thank Manfred in Lange Hong Kong who advised me on the purchase. All photos taken by iPhone.
