Perhaps the most storied department store in Japan – and still one of the highest grossing in the entire world – Isetan Shinjuku is staging its annual Watch Collector’s Week from July 2-22, 2025. Being in Japan, where everything is pursued in a serious minded manner, the theme of the event is “Astronomy and Timekeeping”. And in typical Japanese fashion, the event also has an accompanying manga, or Japanese comic book.

The event encompasses both watches on show as well as historical displays and talks. Participating brands range from establishment names like A. Lange & Söhne and Tudor to independent watchmakers including H. Moser & Cie. and Ressence. Several brands will debut Isetan-exclusive limited editions, including Grand Seiko and Kudoke.

One of the highlights of the event is the exhibit of Shellman, the Tokyo-based independent watch retailer that has concessions in Isetan Shinjuku and other prestigious department stores.

Shellman’s display is centred on Christiaan van der Klaauw, the longtime specialist in astronomical watches, as well as Hermle, the German clockmaker that produces various clocks with astronomical displays.
