1950s IWC Cal.89 “Hermet” ROUND Jumbo in Rare 38mm Case


The popular 1950s “hermet”, a rare large-size 38mm stainless steel water-resistant model with the famous Cal.89. The large case is the largest and rarest of the “hermet” series, measuring 38mm in diameter. The silver dial with its simple design and blued steel hands with luminescent numerals has aged beautifully, and together with the jumbo case, it is a masterpiece with an overwhelming presence. The watch is equipped with the famous Cal. 89, one of IWC’s most famous central-seconds movements.
