Established in 1935, a few years after the devastating Great Kanto Earthquake, Yoshida & Co. was founded by impassioned designer and craftsman Teruyuki Yoshida. Kaban’s penchant for quality and timeless bags carried the brand through its formative early years, eventually developing into one of the Yoshida & Co.’s staple brands, Porter. To celebrate the 77th anniversary of the founding of Yoshida Bag Factory, Porter has joined American watchmaker Hamilton on a two-piece collaborative collection acknowledging the brands’ shared forbearance and vitality throughout the test of time. The interchangeable model features the signature Hamilton Khaki casing and two differentiated watchband options. A slim black leather strap embodies a level of sophistication and cleanliness while a more casual discretion is given to a custom Porter nylon-constructed band. A limited supply of pre-orders will be made available through ZOZOTOWN at a price of ¥77,000 JPY (approximately $1,004 USD), while an official release will not arrive until March 3, 2012.
