As far as 2nd hand market is concerned Moser watches usually are sold at a very steep discounts. And if you love your Moser and sell it - you might want to buy the watch again, that will be frustrating for the wallet. At the same time I strongly do not recommend selling small Lange as it is a work of art. Like all the Lange produced.
Maybe save a little and buy L1 while keeping Saxonia and Moser?
