The Casio F-B100W-1B (also designated across international catalogs as the F-B100W-1BV or within the core F-B100W series) is an ultra-sleek, monochrome retro-smart Japanese digital timepiece from Casio’s celebrated Vintage and Standard Digital Collection. Building directly upon Casio’s legendary octagonal digital profile that has defined everyday wristwear for generations, this reference pairs iconic 1980s retro charm with a contemporary blackout stealth aesthetic, health-conscious fitness tracking, and eco-friendly construction. Among horology enthusiasts, collectors, and everyday carry tastemakers, it has garnered defining community nicknames—the "All Black", "Stealth Retro", "Blackout Digital", "Negative Display", "Bluetooth Step Tracker", or "Shadow Square"—for its murdered-out monochromatic design, high-contrast negative digital LCD screen, muted grey accent graphics, and seamless Bluetooth smartphone connectivity. It unites a lightweight resin case in an optimized 38.1mm width (measuring 41.9 × 38.1 × 8.8 mm) with a dark negative digital LCD display, in-house Japanese digital quartz module engineering powered by Module 3589, a bio-based resin band, daily water resistance, and an integrated resin strap construction. Perfectly calibrated for gentlemen seeking an understated, featherlight, and technologically capable daily digital watch that transitions effortlessly from athletic training and workouts to modern minimalist office environments and casual night outs. The defining visual appeal of the F-B100W-1B lies in its tactical, all-black execution that strips away bright primary accents in favor of subtle monochromatic tones. The black faceplate perimeter is rendered with muted stealth-grey typography and clean perimeter accent lines, framing the lateral pushers, modes, and sensor indicators without visual clutter. At the heart of the dial sits an upgraded reverse-contrast (negative) liquid crystal display (LCD) that features bright, luminous digits against a deep black background. In addition to primary timekeeping (hours, minutes, seconds, year, month, date, and day of the week), the multi-segment screen incorporates an active step-tracking readout showing real-time step counts from 0 to 999,999 steps, a step goal progress indicator, a six-level hourly step graph illustrating activity over the past 7 hours, and an automated step reminder alert system that gently informs wearers with an on-screen prompt and audible beep when activity has remained stagnant. For low-light situations, an integrated high-efficiency green LED backlight with selectable illumination duration (1.5 or 3 seconds) and afterglow illuminates the negative display with crystal-clear visibility. Beneath its stealth exterior, the watch is powered by Casio’s newly engineered in-house Module 3589 digital quartz caliber, combining traditional Japanese electronic reliability with energy-efficient wireless communication. Operating with a standalone accuracy tolerance of ±15 seconds per month, the watch features Mobile Link technology via Bluetooth®, syncing seamlessly with the official CASIO WATCHES smartphone app. Through the app, the timepiece provides automatic time synchronization four times daily, effortless watch configuration, life log data management to track daily steps and caloric burn, quick access to approximately 300 world time cities, dual time home-swapping, time-and-place logging, and a handy phone finder function. Despite its built-in 3-axis accelerometer and wireless connectivity, the movement operates efficiently on a standard CR2016 lithium coin cell, delivering approximately 2 years of battery life, complemented by a low-battery warning and an intelligent power-saving function. The case is engineered with balanced, ultra-comfortable unisex proportions, measuring an official 41.9mm in case length (lug-to-lug) by 38.1mm in case width (diameter), with an ultra-thin profile thickness of just 8.8mm and an exceptionally lightweight build of only 26.0 grams, ensuring an airy, flush, and fatigue-free fit on the wrist all day long. The case housing is crafted from shock-absorbing resin, while the flexible vented strap is made from bio-based resin, synthesized using renewable organic biomass resources such as castor oil and corn to actively reduce environmental impact. Dial protection is provided by a flat resin glass engineered to withstand everyday impacts and shocks. Built for everyday active resilience, the watch incorporates a solid stainless steel four-screw caseback providing certified daily water resistance, safeguarding the internal electronics against sweat, light rain, accidental splashes, and hand washing. The timepiece comes completed on an integrated black bio-based resin strap with an adjustable pin-buckle clasp, comfortably accommodating wrist circumferences from 145mm to 215mm.
