Patek Philippe, Reference 425

This reference is launched in 1934 and remained in production until the early-1960s. The majority in yellow gold and platinum, more rarely in rose gold, even more rarely in white gold. Around 2 500 examples were produced. The model was replaced in 1960 by Ref. 2461 (slightly larger). The watch is so-called “Tegolino” by collectors.
