I have been happily following along between many of the different aspects of value and cost considerations.
In a way, you are also challenging the value in this price range ($30-60k)in general.
Cars come in mind as a natural choice; although I assume folks here that are contemplating this range consider cars that are 100k + as well.
From a craftsmanship perspective, my bias is toward Lange and in the pre owned market pricing of “value”.
The much higher Lange maintenance pricing does put a damper on things, but it does seem natural considering the sophistication around the movement architecture and the rebuilding the movement twice.
One could argue that Patek is “wise” as they approached the maintenance of their watches for longevity and therefore have simpler and less decorated movements in this price range.
