As more & more former of the 'Mechanical watches are for old white men!' youngsters began to amass huge mechanical gen collections & the nouveau riche began to convert their fiat investments into tangible assets like high end watches, the big 3 brands quickly became unrealistically pricey &/or unobtainium. Because of this, many of the gen forums have become literal ghost towns. At the same time, for a variety of reasons, there has been a reshuffling of traffic to rep forums, which left sites like ours in the same boat as the empty gen forums.
From what I have seen, RWI is probably the most traffic'd rep forum today. At least that is where I 1st discovered the incredible current crop of modern 116xxx Daytonas with cloned 413x movements (see my review/frankening threads for details).
Vintagerolexforum still seems to be fairly active, but mostly with regulars since few others can still afford the price of (vintage Rolex) admission.
