Description

AN ICON SINCE 1989 — THE WORLD'S MOST POPULAR DIGITAL WATCH — Introduced in June 1989 as a successor to the F-87W, the F-91W is popular for its low price, long battery life, and iconic design. As of 2026, production of the watch has reached 100 million units, making it the most sold watch in the world. A timeless design, unchanged since launch, that has earned a global cult following across generations.
FEATHERLIGHT & SLIM — Urethane resin is employed for the case and band, and the module features a reduced number of components — every element of construction was reconsidered to secure high quality at an affordable price, resulting in a global hit watch that offers both affordability and long-lasting reliability. The case measures 38.2 × 35.2 × 8.5mm and weighs just 21 grams — barely noticeable on the wrist.
1/100-SECOND STOPWATCH WITH SPLIT TIME — The 1/100-second stopwatch covers elapsed time, split time, and 1st-2nd place timing up to 59'59.99" — precise enough for sports, training, cooking, and any timed activity. Handy features for day-to-day life also include a daily alarm, water resistance, and LED light functions.
DAILY ALARM | HOURLY CHIME | AUTO-CALENDAR | LED LIGHT — Module 593 delivers functions for a daily alarm, chronograph/stopwatch, annual calendar, and hourly chime, with selectable 12 or 24-hour format. The auto-calendar and LED backlight round out a complete, practical feature set in a package that fits any wrist from 145 to 200mm.
7-YEAR BATTERY | MODULE 593 | 18MM LUG WIDTH — Powered by a CR2016 battery with an approximate 7-year life — often lasting 10 or more years in practice. The F-91W has an 18mm lug width, meaning standard 18mm NATO straps fit directly without any modification — making it one of the most customizable and mod-friendly watches available at any price point.
