when you read about watch valuations over time, Rolex and PP always gets mentioned for holding and typically increasing in value. What's the thought on other HH brands such as Lange? Should one expect their Lange's to increase in value over time? Given their craftsmanship and gorgeous movements, i'm surprised they don't stack up or gain mention like the Patek's. I have a rose gold Lange 1 and curious how the market might value this over time. I suppose that might inform my next purchase as well when considering a PP or something similar.
