Casio designed the CRW-H001S-8 as an innovative smart ring watch. It blends traditional watchmaking aesthetics with modern wearable technology on your finger.
The company miniaturized iconic digital timekeeping features into a compact metallic ring format. This model serves as both a stylish piece of jewelry and a functional digital accessory.
You can enjoy iconic digital watch aesthetics directly on their hands. The concept celebrates historic Casio innovations while embracing modern smart functionality.
Casio engineers scaled down a standard watch module into an ultra-small form factor. This creative engineering delivers advanced health monitoring in a classic digital layout.
Specification
The overall case length measures 25.2mm across the top surface. The case width reaches 19.5mm to fit comfortably on the finger. Engineers crafted the case thickness to just 6mm for a low profile.
The CRW-H001S-8 specifically represents the small size variation in this series. This small version features an inner ring diameter of 19.3mm and the internal circumference measures 60.7mm for a precise fit.
The CRW-H001M-8 represents the medium size. This version features an inner ring diameter of 20.1mm and an internal circumference of 63.1mm.
The CRW-H001L-8 represents the large size. This model features an inner ring diameter of 20.9mm and an internal circumference of 65.6mm.
The total structure weighs approximately 19 grams, feeling substantial yet lightweight. You can wear the device daily without feeling heavy or restricted.
Casio uses metal injection molding technology to create the entire outer body. This advanced molding technique fuses fine metal powders with special resin compounds.
The process forms a single seamless monocoque stainless steel frame. The caseback and ring band unify into one continuous piece of precision steel.
The exterior exhibits fine metallic dimples that mirror classic watch link bracelets. The metallic surface displays a polished silver finish for an elegant shine. This seamless construction ensures both durability and refined visual appeal.
A high-contrast digital display sits in the center of the ring face. The surrounding dial frame displays a sleek metallic silver color finish.
Subtle brushed textures highlight the frame, framing the dark liquid crystal panel. A multi-segment LCD screen clearly displays hours, minutes, and seconds.
The clean digital layout offers excellent readability despite the tiny footprint. Durable mineral glass covers and protects the LCD face against scratches.
Advanced glass adhesive seals the mineral window tightly to the steel body. This protective glass maintains crystal clarity under various lighting conditions.
The monocoque construction provides basic water resistance for normal use. You can safely wash hands or handle light rain splashes.
The watch uses a specialized miniature digital smart module inside. High-density mounting technology allowed Casio to shrink the module tenfold.
Instead of a traditional strap, the ring watch uses an integrated steel band. The band forms a complete solid ring directly attached to the case.
Smooth interior contours reduce friction against finger skin during extended wear. This ergonomic shaping allows comfortable all-day health tracking and timekeeping.
