Casio brings back its impossibly small ring watch

Second chance: Casio's miniature ring watch returns to American market

Casio announced the US restock of its Ring Watch CRW001-1 on July 1st, bringing back the small timepiece that sold out quickly after it came out in America in late 2024. The restock follows successful lottery sales in the UK and Japan, showing that people around the world want this digital watch that goes on a finger.

The Ring Watch CRW001-1 shows Casio’s bold way of looking at wearable technology—it shrinks standard digital watch functions into a ring that measures only 25.2mm across and weighs 16 grams. Even though it is small, the timepiece keeps necessary features, including support for two time zones, a stopwatch that measures 1/100th of a second, and hourly flash alerts.

Casio US confirmed the July 1st restock on Instagram, saying the watch would only be available through the brand’s online store, not in physical shops. Compared to the lottery systems in other places, American customers will buy the watch in the order they arrive—this might cause a lot of competition among people who collect things and those who like technology.

The small digital screen has a backlight so you can see it in different light. The stainless steel build makes it sturdy, even though it is small. The ring fits size 22 fingers (US 10.5, EU U), and you can adjust it down to size 19 (19mm inner diameter) or size 16 (18mm inner diameter).

The engineering needed to put normal digital watch parts into a ring shape shows how well they made it. The 1/100th second stopwatch is as exact as bigger Casio watches. Travelers who want to check the time without others knowing will like the two-time zone feature.

Casio did not say the exact restock time but told interested customers to sign up for email notifications about when it would be ready. That way may help manage the internet traffic while making sure serious buyers learn about buying chances in time.

The Ring Watch’s appeal shows more people are interested in other types of wearable devices, not just ones worn on the wrist. Casio’s good result with this unusual approach shows that people want new watch designs that question common ideas about what a watch should look like.

The quick sellout after the US launch, along with international lottery systems, suggests that collectors are very interested and that the watch might sell for more later. Casio has not said anything about more restocks in other places after the July 1st US availability, keeping the watch special.

This restock gives American buyers a second chance to get one of the most noticeable wearable technology releases of the year, bringing together Casio’s history with digital watches and its push to make things very small.

IWC expands top gun collection with mojave desert ceramic pilot watch
Desert inspiration: IWC's sand-colored ceramic pilot watch honors naval aviation heritage
IWC Pilot’s Watch Automatic 41 TOP GUN Mojave Desert

IWC Schaffhausen is expanding its military aviation collection with the Pilot's Watch Automatic 41 TOP GUN Mojave Desert, the latest addition to the brand’s "Colors of TOP GUN" series. This watch features ceramic construction that pairs desert-inspired aesthetics with Swiss precision, drawing inspiration from navy flight suits and the rugged terrain surrounding the China Lake air base in California’s Western Mojave Desert.
The 41mm case showcases IWC’s forty years of ceramic expertise, rendered in their proprietary "Mojave Desert" color—a muted earth tone blending beige and khaki. This distinctive shade does more than look good; it directly references the flight suits worn by navy pilots and the arid landscape where US Navy aviators train at China Lake.
IWC’s ceramic process highlights how complex achieving this subtle color actually is. Artisans form ceramic from powdered raw materials into "green body" shapes, machine them closer to their final form, and then fire them in a kiln. This high-temperature process makes the ceramic exceptionally hard and scratch-resistant. The Mojave Desert color is achieved by carefully mixing zirconium oxide with metallic oxides.
The challenge increases because the color changes during firing, requiring extensive testing to achieve the exact tone. This meticulous approach reflects IWC’s long-standing dedication to advanced materials—a legacy dating back over 150 years, making them pioneers in both titanium and ceramic watchmaking.
The watch’s design maintains a unified color scheme. The brown dial features understated minute scales and numerals that glow with Super-LumiNova for legibility in low light, matching the ceramic case. A beige rubber strap with a fabric inlay and a titanium pin buckle completes the look, adding both durability and comfort.
Technical excellence is evident in the IWC-manufactured 32112 caliber. This automatic movement uses a pawl winding system to deliver a 120-hour power reserve. Its 4Hz frequency ensures precise timekeeping, and the bi-directional rotor efficiently stores energy from even the smallest wrist movements.
The titanium case back is engraved with the TOP GUN logo, underscoring the watch’s connection to naval aviation while also reducing weight. The choice of titanium further demonstrates IWC’s expertise in working with advanced metals, complementing their mastery of ceramics.
This watch joins a growing Mojave Desert collection, which includes the Big Pilot's Watch Perpetual Calendar TOP GUN Edition, the Pilot's Watch Chronograph 41, and the Big Pilot's Watch TOP GUN Edition. All feature the signature sand-colored ceramic, but offer different functionalities and case sizes.
IWC’s commitment to sustainable luxury is evident in their careful sourcing of materials and efforts to minimize environmental impact, ensuring these watches embody both technical mastery and responsible craftsmanship. The brand’s focus on transparency, reuse, and care results in timepieces built to last for generations.
The Pilot's Watch Automatic 41 TOP GUN Mojave Desert demonstrates how military inspiration can be transformed into civilian luxury, blending professional tool heritage with contemporary design through advanced materials and renowned Swiss watchmaking expertise.
