For our interested forum members, reference 5075 in enamel, which was introduced in year 2000 and offered until about 2004, is the direct predecessor (in a sense, along with ref. 5076) of today's incredible, out-of-catalog Rare Handcraft production: refs. 5077, 5086, 5088, 5089, 5738, and perhaps my favorite, 5177

Thanks again for sharing with the Patek forum --- and my sincere best of luck to the fortunate new owner of this incredible Patek!
