**Reference:** **Model:** Seiko SOTTSASS SBBP011 **Year Produced:** April 1993 **Timestamp:**  [https://imgur.com/a/s7SMi00](https://imgur.com/a/s7SMi00) **Album:**  [https://imgur.com/a/SM6X7mq](https://imgur.com/a/SM6X7mq) **Features:** **The History.** The SBBP011 is a collaboration between Seiko and an Italian design icon - it sits at the intersection of horology and modernist art. Ettore Sottsass began his career as an architect but applied his avant-garde style to everything from ceramics and furniture to typewriters and, eventually, watches. In the early ’90s, Seiko commissioned him to design a small collection of chronographs, and the result is one of the rare cases where the crystal becomes the defining feature of a watch. **The Shadows.** The minute track, hour indices, and even the SEIKO logo are printed on the underside of the crystal. When light catches them, they cast shadows - not onto the dial beneath, but onto an invisible secondary crystal layer. Seiko has always been coy about the exact mechanics, but as you can see from the image above, the shadows appear to float between the dial and the crystal. The effect is dynamic, playful, and unmistakably modernist - a clever optical illusion that shifts with your perspective. **The Functionality.**  A 30-minute chronograph counter occupies the 12 o’clock sub-dial, while a circular date display sits at 3 o’clock. The alarm function, which also serves as a GMT indicator, is positioned at 6 o’clock, and the running seconds can be found on the 9 o’clock sub-dial. This arrangement leaves the smooth-sweeping chronograph seconds hand on the central post **The Rarity.** In 2019, Wright Auctions managed to assemble a complete set of these rare timepieces - presumably the only time all the designs have been in the same room together in decades. Sadly, they were auctioned off individually, with final prices ranging from $1,875 to an impressive $5,938. The watch on offer today is an original from 1993 – Seiko produced a lacklustre rerelease of these, with a 3 subdialed setup and a single crystal layer, in 2016. **Details:** **The Condition**: In very good condition. Any marks are not noticeable or significant. Most importantly, as shown in the pictures, the crystal is without blemish.
