Not suitable for immersion: no swimming

The Architecture of an Icon
The silhouette of the F-91W is instantly recognisable. Its moulded resin case, just 9 mm thick, fits perfectly to the wrist. The grey dial, of absolute simplicity, serves as a setting for a digital display of remarkable clarity, protected by mineral glass resistant to everyday scratches.
The pin buckle on the black strap ensures precise adjustment and secure fit. Each component, from the membrane of the push buttons to the alarm tone, meets rigorous specifications. This construction delivers 30 metres water resistance, sufficient to withstand splashes and rain.
The Logic of an Instrument
The quartz movement is the heart of this timekeeping machine. It drives the essential functions with relentless accuracy: time and date display, stopwatch to 1/100th of a second, and daily alarm. The interface, reduced to three buttons, allows intuitive and immediate operation.
There is no superfluous complication here, only the efficiency of a tool designed for constant use. The battery longevity and overall robustness make it a companion for every moment, indifferent to the elements.
Reach and Legacy
This vintage Casio men's watch transcends convention. It pairs with equal ease to casual wear or a blazer over jeans, bringing a touch of retro authenticity. Its timeless design, popularised by cultural references such as Back to the Future, makes it both a personal and iconic object.
It suits those who seek the essentials, without aesthetic or technical compromise. It is the watch of forgetting: once on the wrist, it fulfils its function without demanding attention, freeing its wearer.
This model is covered by the 2-year warranty. A 14-day returns period allows you to verify its suitability to your style.
