Two Regular Models, Three Special Edition Models. Total of Five Models Available.
Mr. Yoshikage Kajiwara, representative of LOWERCASE, a creative consulting firm that handles consultations for various brands, supervised a solar digital watch inspired by two historical models released in the 1970s.
The “Prospex Fieldmaster” supervised by Mr. Kajiwara is a field watch with a 20-bar water-resistant case that employs a unique outer protective structure to enhance shock resistance, and features a digital watch font that reproduces the numerals from the world's first 6-digit display digital watch.
By placing most of the push buttons on the left side of the case, it prevents accidental operation during wear while also ensuring that wrist movement is not hindered, demonstrating meticulous consideration.
The solar digital caliber S802 is equipped with a backlight function that illuminates the EL light when the glass on the front of the watch is lightly tapped, as well as a dual time function that simultaneously displays the time in 44 cities worldwide and the local time.
All released models are monotone. The regular models come in white and black. The navy model, a special order from nano・universe, is limited to 500 pieces. Additionally, the all-black and gray models, special orders from Beauty & Youth, will also be available in limited quantities of 500 pieces each.
