This IWC Schaffhausen Tank, described as 93 years old, reflects the streamlined geometry of the Art Deco period with a distinctive crystal design that shapes its presence on the wrist. Beneath the case sits the Cal. 87 movement, a period IWC caliber that underscores the brand’s watchmaking tradition of robust, precise mechanisms. For the contemporary collector, the piece offers a direct tactile link to early 20th‑century aesthetics and mechanical craft, valued for its historic design language and traditional movement construction.
