IMO it’s the best bang for buck in most cases and you get work closely with the artist making your watch to get exactly what you want.
To this point, my experience ordering a sub 15k watch from Benzinger is better than an almost 100K piece from Lange.
My next big purchase will 100% be an independent again. I don’t see the value of big brands in most cases. Romain Gauthier for example annihilated a similarly priced pp, ap or vc. I realize pp/ap are technically independent but the reality is that they are multibillion dollar corporations, not true entrepreneurs and artists like Gauthier.
