I do not (yet) own a Lange but am trying to learn more about the brand. I want only a few watches, but I like watches which are classic models which stick closely to the original (even if they are subject to minor cosmetic updates). For example I have a Rolex Explorer 1 36mm and an AP Jumbo, both of which I like very much.
Some watches seems to change considerably over time - in particular the recent fad for big watches has caused some models to be upsized, often destroying the purity of the original design. I notice for example that the 1815 in its short life has been subject to changes in size and movement, which to me makes it less appealing.
However, am I right in thinking that the "basic" Lange 1 has always been and is still essentailly unchanged from the first 1994 model - ie same movement, case size and design? Have there been any significant changes since its inception?
