Bring a Loupe: A Piaget Dress Watch, An Eterna-Matic Super Kontiki, A Girard Perregaux Olimpico, And A Trio Of Lemania Tg 195s
This "Bring a Loupe" feature highlights several notable vintage watches appearing at auction. Among them is a Piaget dress watch with the historic 12P ultra-thin automatic movement, an Eterna-Matic Super Kontiki diver, and a Girard Perregaux Olimpico chronograph, alongside other interesting pieces like Lemania TG 195s.
The Piaget ref 12423 features a tropicalized dial with uneven aging and an unpolished white gold case, powered by the 2.3mm thick 12P microrotor automatic movement from 1960.
The Eterna-Matic Super Kontiki, estimated between €1,500-2,500, is a 39-40mm diver with a large rotating bezel and Eterna's patented ball-bearing system on the oscillating weight.
The Eterna Super Kontiki example has a replaced crown and less attractive, though original, lume, but is considered an honest, worn example of a classic diver.
Girard Perregaux Olimpico chronographs were introduced in 1968, made in limited numbers (under 1,000 per reference), and came in variants like panda and inverse panda dials.
