57985 SEIKO FIELD MASTER Ref.1420-0140
This model features an analogue display with a rotating bezel, paired with a matte black dial and luminous pencil hands. The indexes are primarily bar-shaped, with Arabic numerals at 3, 6, 9, and 12 o’clock for enhanced practicality. The digital module at the lower section includes a timer and alarm, while the crown at 3 o’clock allows the user to check the date and day of the week. The screw at 4 o’clock secures the watch to its base, designed to be interchangeable with the included compass or map meter.

This reference integrates a digital display within the dial, with the pusher at 8 o’clock switching between date, time, alarm, and timer. The 10 o’clock button controls alarm and timer functions. A black dial with luminous-filled hands ensures legibility, while the red-tipped luminous seconds hand provides a striking accent. Original accessories—price tag, strap, and instruction manual—are included, further enhancing its collectability.

Distinguished by gold-tone printing, this model places the digital display at 12 o’clock. The pusher at 8 o’clock cycles through day, alarm, local time, and stopwatch modes, while the combination of analogue and digital systems enables three separate time displays. Though more complex in operation, the original instruction manual is included to guide use.

All three of these watches were released in the 1980s as part of Seiko’s Fieldmaster line, a collection that embodied the brand’s philosophy of tool watches designed for survival and exploration. Each model reflects the era’s progressive integration of analogue and digital displays, enhanced water resistance, and expanded functionality.

While it is not uncommon to encounter these references individually on the market, finding the trio together is exceptionally rare. As a set, they vividly illustrate the evolutionary path of Seiko’s technical innovation during the decade, and their collective presence greatly amplifies their value as collector’s pieces.

BRAND

First introduced in 1984, the Fieldmaster was conceived as a “survival watch for adventure.” The name and concept have been carried forward intermittently, defined by features such as extreme cold resistance for polar expeditions, hybrid analogue/digital displays, dial rings engraved with emergency signal codes, functional rotating bezels, and lightweight titanium cases. Prioritising usability, legibility, and durability in outdoor environments, the Fieldmaster remains a symbolic expression of Seiko’s philosophy of adventure timepieces.
