The example offered for sale here is a hardly seen "Idemitsu Special" that is created to commemorate the 60th anniversary of the founding of the Idemitsu Foundation.

Similar to the "Toshiba Special" the "Idemitsu Special" has a custom case back with commemorative text on it with model and serial number on the inside of the case back.

The example offered is powered by the calibre 5645. The absence of day complication allows the watch to have a more symmetrical aesthetic.
