Notes

Dial case and movement signed. DIAM. 40 mm. THICKNESS 8.5 mm. Produced between 1980 and 1983, this extremely rare Jumbo Ingenieur was produced in only 56 pieces. Bought new by the owner in 1982, for an eye-watering CHF 19"?000 (the owner recalls this was a special price as the official retail was around 22"?000 CHF), this is the first time a Jumbo Ingenieur reference 9701 has appeared at auction.
