    Casio F-91W Redefined: Italy-Made EVT-01 with Aluminum and Sapphire Glass

    Key Takeaways

    1. The EVT-01 is a sophisticated upgrade of the Casio F-91W, featuring a CNC-machined aluminum casing and sapphire crystal, appealing to those wanting a more premium feel.
    2. Unlike typical DIY mods, the EVT-01 is handcrafted in Rome, influenced by custom car culture, making it a unique artisanal product.
    3. The Kickstarter campaign reflects a niche market interest, with over $12,000 pledged towards its $18,735 goal, indicating excitement among collectors.
    4. The EVT-01 is priced at $250, significantly higher than the original F-91W, due to its handcrafted nature and premium materials used.
    5. Plans for future updates include customizable interchangeable front plates, responding to positive feedback from early backers.


    For many years, the Casio F-91W (currently priced at $21 on Amazon) has been a symbol of digital watches – affordable, light, and nearly unbreakable. Its design can be seen on both fashion catwalks and the wrists of truck drivers alike. However, with the introduction of the EVT-01 on Kickstarter, a pair of Italian watchmakers believe that some enthusiasts might be ready for something a tad more… sophisticated.

    What’s New Here?

    So what’s the deal? The EVT-01 essentially remains a Casio F-91W – it has the same movement and familiar display. The notable changes lie in its surroundings. Instead of the usual plastic and resin, you get a CNC-machined and anodized aluminum casing, a sapphire crystal, and meticulous craftsmanship that most digital watches lack. This is a niche modification for those who appreciate the Casio aesthetic but desire a more tactile experience that doesn’t feel disposable – something that stands out subtly.

    The Unique Appeal

    That was one of my first thoughts when I came across the EVT-01. After all, there are plenty of Casio modders out there – metal cases, customized dials, and strap changes have been around for ages. We recently talked about the Ollee Watch mod, which is basically the opposite of the EVT-01 (same watch, different custom design). What makes the EVT-01 distinct is its concept: it’s not just a quick DIY kit or a simple upgrade from eBay. Everything is rebuilt and refinished in Rome, heavily influenced by custom car culture and Italian artistry. There’s even an exclusive violet version with titanium screws for those wanting to go all-in on collecting.

    Pricing and Response

    If the starting Kickstarter price of $250 made you raise your eyebrows, you’re not alone. The original F-91W typically sells for $20-$25, and even the most premium mass-market metal mod kits rarely exceed $150. Still, a significant number of people find it appealing, as seen in the Kickstarter’s progress – $12,229 has been pledged towards the $18,735 target as of this writing. Early images shared from Reddit to various watch communities showcase considerable excitement and backing. The feedback thus far indicates that there’s a niche, albeit a small one, for an artisanal take on the F-91W.

    Below are the questions I asked the EVT-01 team, along with their responses untouched. This is exactly how our conversation unfolded:

    Q1. What kind of feedback have you gotten from early backers or users, and how do you plan to use that feedback for future updates or iterations?

    A: We were surprised by the initial feedback. We knew the EVT-01 looked good and was well-designed, but once we launched it, the user response across different social media was really positive, creating lots of hype. We think we’ve managed to make waves in the digital watch scene. Regarding future updates: We’re looking into adding interchangeable front plates to the Casio, which would let users customize their watches even more.

    Q2. Your project mentions CNC-machined anodized aluminum and a sapphire crystal – how did you choose these materials?

    A: We’ve been in the watch-making business for several years, using materials like carbon fiber, anodized aluminum, and sapphire crystal throughout our range. Aerospace-grade aluminum, in particular, is lightweight and very durable – perfectly in line with our goal of making watches that feel light on the wrist. From the first time you wear one of our watches, it should feel exceptional.

    Q3. Given the current Kickstarter price of around $250, how can you justify the cost compared to other modders or upgraded models, especially since the base F-91W is just $20-$25?

    A: The EVT-01 is our first digital watch, made through a handmade process that’s far from mass production. Inside, it has a movement that costs only 20 euros, but it’s not just any movement: it’s the Casio F91W, the most iconic digital watch ever. For us, the overall product is what gives the EVT-01 its true worth. What differentiates us from others is the artisanal touch we add to every watch that leaves our workshop.

    The Kickstarter campaign for the EVT-01 offers several reward tiers, all limited in availability and shipping worldwide starting March 2026. Early bird packages include single and double-watch bundles, with prices from €220 (~$257) for first backers to €300 (~$350) for the Kickstarter-exclusive “Glossy Violet” edition. Each watch features a CNC-machined anodized aluminum case, sapphire crystal, 100 meters of water resistance, and the Casio F-91W movement. The special editions are limited – one violet edition has only 20 units, while grey and bronze versions are available in runs of 30 or 50 each. Every watch comes with a two-year warranty and at least one extra strap.

    You could say the EVT-01 is an over-engineered F-91W, and you wouldn’t be wrong (mostly). For many, the original $20 version is still the best value in watches. But for a smaller group who already knows the story and desires something unique, the EVT-01 offers genuine craftsmanship, a niche appeal, and an Italian twist on a classic favorite. Whether or not you believe a digital Casio deserves this much attention, the EVT-01 makes a compelling argument for treating timeless design with more care and creativity.

  • Discover Hidden Easter Eggs in Casio Watches with CheckMag

    Discover Hidden Easter Eggs in Casio Watches with CheckMag

    Key Takeaways

    1. The F-91W and A158WA models have a hidden feature that spells “Casio” on the display when a specific button is pressed, helping to verify authenticity.
    2. The AE-1200, known as “Casio Royale,” has a diagnostic display test that checks the LCD segments, which can also help identify counterfeit watches.
    3. G-Shock models with advanced features include hidden diagnostic modes activated by button combinations, allowing for self-tests and solar charging level displays.
    4. Limited-edition models feature special backlights that reveal logos or images when activated, adding a unique visual element.
    5. Some Casio watches, like the DW-5600, include little-known functions, such as an auto-repeat feature for the countdown timer, enhancing their charm and functionality.


    Everybody enjoys a little secret, and Casio’s simple digital watches have a few surprises hidden within them. From secret diagnostic modes to unexpected display features, these “Easter eggs” can transform ordinary timepieces into topics of discussion. Just like traditional Easter eggs, they are not easy to find – you wouldn’t know they were there unless you press the correct sequence of buttons. Let’s explore some of the concealed features found in popular Casio models.

    The F-91W and Its Hidden Message

    One well-known Easter egg from Casio is cleverly disguised on the F-91W and its relatives. If you press and hold a specific button (hint, it’s the lower-right one), the display will momentarily spell “Casio” using its LCD segments. This secret screen is likely a way to verify authenticity. The classic A158WA (which uses the same module as the F-91W) can also perform this trick, along with the newer W-217H, which is pretty neat considering even Casio’s most affordable models have Easter eggs. In fact, Casio enthusiasts and collectors once relied on this to identify fakes – although counterfeiters soon learned how to replicate it.

    The AE-1200’s Diagnostic Display

    The popular AE-1200, affectionately called “Casio Royale” by fans, also has a hidden feature. By pressing and holding a specific trio of buttons (the two buttons on the left and the lower-right button together), the watch will enter a diagnostic display test. All segments on the screen will light up simultaneously, usually followed by a code number. If you think this is just for aesthetics, it’s actually an LCD test that checks if every part of the display is functioning correctly. This feature can help verify the authenticity of a module (a counterfeit might not show the sequence right). It’s a fun trick to watch your AE-1200’s world map and numbers all light up together before returning to regular timekeeping.

    G-Shock Models and Their Unique Functions

    Casio’s G-Shock line, particularly the classic square models, has its own fun quirks. Many G-Shocks with advanced features like a tilt sensor (for auto backlight) or solar power have special diagnostic modes activated through three-button combinations. For instance, on a GW-M5610 or GW-5000 (solar-powered G-Shock squares), one hidden combination will flash all LCD segments in a test pattern, while another displays the solar charging level (showing “8888” when light is detected). Another screen might present a puzzling code of letters and numbers, which essentially indicates the watch checking its internal systems. It’s a greatly simplified version of a car’s “check engine” diagnostics. Though these features aren’t used daily, it’s incredibly cool to know that G-Shocks can conduct a self-test.

    Limited-Edition Models with Special Backlights

    Not all Easter eggs are found in the numbers; some are hidden in the illumination. Over the years, Casio has launched various limited-edition models where a special image or logo appears when you activate the backlight. In collaboration models, a company logo or character might be printed invisibly on the dial, only visible under the electroluminescent (EL) backlight. For example, one Bodega x G-Shock edition shows a world map outline glowing red against the green EL light.

    Casio’s hidden features extend beyond visuals as well. Some models offer extra functions that aren’t immediately apparent. For instance, the DW-5600 has a little-known auto-repeat function for its countdown timer (you can activate it by holding a button in Timer mode). This is a handy feature, but you’d likely never discover it without consulting the manual or online discussions. All these unique traits add an additional charm to Casio’s watches. Because sometimes, it’s not the features you use every day that make a watch stand out. It’s the surprises you find when you weren’t even searching.
