AndoAndoAndo Luckyshroom x Ando Flathead (Ando Edition)

Archive · used only

AndoAndoAndo is a Japanese maker of metal cases for Casio digital modules, and the Flathead is the design of the Swiss microbrand Luckyshroom: a machined titanium case, caseback included, around Casio's 3551 module, the one inside the classic F-91W. This Ando Edition was a run of five. The case is 33 mm across and 8.3 mm thick, with a sapphire crystal, and the maker describes the titanium as Grade 5. A run that small has no second batch, so it is now a watch to find used. It listed at $536.
