When speaking of vintage watches, the first name to come in every mind has to be Casio. These electronic digital watches literally changed the way watches were made and used. And nearly every watch enthusiast had a Casio in their collection.
If you’re one of them, consider yourself lucky because Casio vintage watches are a big deal right now! No doubt they’re in fashion for both men and women, you’d be surprised to know that some models are actually selling for thousands!
In this guide, i’m going to show you some rare and valuable vintage Casio models that are actually worth money, along with some expert tips to identify and value these old timepieces.
Why Are Casio Watches So Collectible?
Casio watches have been different always since, instead of just showing time, it designed watches that could do things. The legacy started in 1974, when they released the Casiotron, which could automatically adjust dates for different month lengths.
This started the digital watch revolution, making old-style mechanical watches look outdated. The 1980s and 90s models were quite innovative, featuring calculators, phonebooks, TV remotes, and even games.
Casio also made these watches durable. The G-Shock series grew to be renowned for being almost indestructible. That’s how some of the old Casios from past decades continue to function well and are highly desirable for their incredible combination of technology, ruggedness, and quirky aesthetic.
11 Rare Casio Vintage Watches Collectors Are Looking For!
Let’s take a look at some of Casio’s most valuable, rare, and revolutionary models that have been sold for hundreds to thousands!
1. Casio TM-100 Transmitter Digital Watch (1987)
This might be the strangest Casio ever made: a watch with a built-in FM transmitter and telescopic antenna that could broadcast your voice to nearby radios. You could speak into the microphone and transmit to any radio tuned to the right frequency within about 100 meters.
Made only in 1987, the model was way ahead of its time, and very few were produced, making it extremely rare today; no wonder it can sell for $1,000 to $3,000+!
2. Casio TSX-1300 Thermo Scanner Digital Watch (1994)
Casio TSX-1300 was an old watch with a very rare design in the early 1990s that had a thermometer inside the watch, which is used to gauge infra-radiation of an object’s surface between -20°C and 200°C.
The model was launched in 1994 in bold colors of yellow, blue, and purple. The thermo scanner function, as well as the moon phase and tide graph functions, was revolutionary for its time, making it an exclusive watch. This lot of two TSX-1300s sold for over $1,970, but single watches can also fetch $800 to $1,000+!
3. Casio C-80 First Calculator Watch (1980)
Casio C-80 changed everything when it launched in 1980 as the world’s first calculator watch with a physical keypad. Casio called it a “microcomputer for the wrist,” and it sparked the whole calculator watch trend of the 1980s.
Today, finding this model in the brown/black version is particularly rare. These watches are sort of the foundation for the smartwatch concept, decades before the Apple Watch existed. Working C-80 examples are getting harder to find as the old electronics fail.
4. Casio G-Shock DW 110th Anniversary Edition (1993)
This is a special edition Casio watch from 1993 released to celebrate G-Shock’s 10th anniversary, with only 1,983 pieces made worldwide. The limited production run and commemorative nature make it highly sought after by collectors.
The model is packed with many features, including a 1/100-second stopwatch, a multi-function alarm, a 24-hour countdown timer, an hourly time signal, and a backlight. Most anniversary G-Shock models are in demand, but this one is special since it was a milestone for the company.
5. Casio AQ-441 Ana-Digi Japan Watch (1980s)
This vintage 1980s ana-digi chronograph Casio combines both analog and digital displays. The unique square-shaped metal case with curved edges houses both traditional watch hands and a digital readout at the bottom.
The chronograph function is displayed through the analog subdials, while the digital portion shows additional timing functions. The red ostrich leather strap adds a premium touch and contributes to the amazing price of almost $1,300 for this rare watch!
6. Casio F-Shock DW-5000C (1983)
This one is every G-Shock collector’s dream! The very first G-Shock ever made in 1983. It introduced the world to the “shock-resistant” watches that could survive a 10-meter drop. Only produced for one year before being replaced, original DW-5000Cs are incredibly rare today, fetching $800 to $2,000+!
7. Casio AE-20W Twingraph Watch (1989)
The AE-20W Twingraph was released in 1989 and stands out with its unique dual-display design. You’ll spot two square displays on the left side; one shows analog time while the other tracks seconds in a rotating circle pattern. The digital time sits at the bottom.
You’ll also find other features, like dual time, a stopwatch, a timer, and multiple alarms in this. This Casio model with module 588 has become quite collectible, especially since it was associated with musician John Mayer. Working pieces can sell for up to $1,500 to $2,000!
8. Casio VDB-1000 Data Bank Touch Screen Watch (1991)
The VDB-1000 was groundbreaking when it came out in 1991 because it was one of the first in the Data Bank line with a touchscreen and had no buttons or crown. The large, full-screen dot-matrix LCD displayed graphics, letters, numbers, and other characters (katakana).
Besides, this model featured the Telememo function for storing contacts and calendar entries, plus world time capabilities. The touchscreen was revolutionary for its time. Since many surviving examples have touch sensitivity issues today, finding one with a functional screen can be a big deal!
9. Casio Marlin W-550 Module 81 Watch (1980s)
The W-550 is considered one of the rarest Casio Marlin watches, with module 81 being the lowest numbered module to appear in any Marlin watch. Released around 1980 as one of the first in Casio’s 100M water-resistant “Marlin” line, this model is so rare that it doesn’t even appear in Casio’s 1993 PINDEX catalog.
The Marlin series was released between 1979 and 1985, identified by the distinctive sailfish logo (not actually a marlin fish). The case of the W-550 is bulkier than other Marlin models like the W-350 or W-450. Today, this model can be worth $300 to $900+!
10. Casio FS-00 Illuminator Film Watch (1980s)
The FS-00 was part of Casio’s ultra-thin Film Watch series that started in the mid-1980s. Known for pushing design boundaries, this model was just 5mm thick and uses the 2190 quartz module with a display set at a 30-degree angle, comprised of 3 rows of dot matrix arrays!
Instead of a boring look, the watch came in exciting options like this translucent blue case and a unique oval digital display. You’ll also find data bank functions, world time, and even an alternative display mode that shows animations of animals.
The Film Watch series was all about being impossibly thin and light, making this model feel almost futuristic when it was released. Today, it’s highly sought after by collectors, fetching $300 to $800!
11. Casio F-100 Digital Watch (1977)
The iconic F-100 was Casio’s first all-resin watch when it launched in 1977, making it super lightweight compared to metal watches. Already a favorite, it became even more famous after appearing in the 1979 movie “Alien,” where Sigourney Weaver’s character wore two of them strapped together.
The watch originally sold for $39.95, but now collectors are paying thousands for original examples because of its connection to pop culture. Even though this one sold $118 due to poor condition, F-100s in working condition can fetch up to $300 to $800!
How to Identify an Original Casio Vintage Watch?
While When buying (or trading) vintage Casio watches, counterfeits and “frankenwatches” (watches made from various parts) are the biggest concerns. That’s why it’s crucial to understand the key features of authentic vintage Casios, like their build, logo, and designs.
Below is a detailed breakdown of seven important things you need to look for to identify a genuine Casio model from a fake/reproduction:
1. Brand Logo and Printing
The first sign to verify a Casio watch’s authenticity is to check the logo. Genuine vintage Casio models feature the word “CASIO” on both the watch face and the back. Real Casio text looks crisp, while fake text often looks blurry, has weird spacing, or is misaligned.
Also, many fake G-Shocks will say “G-SHOCK” on the front but forget to include “CASIO” anywhere.
2. Serial & Model Numbers
Every real Casio has its birth certificate engraved on the back.These details are crucial to identify the model and check if you’re looking at a real model or a reproduction.
Generally, you’ll find the following information on the back:
- A model number that matches official Casio records
- A serial number (sometimes under a barcode)
- The module number (this tells you the movement type)
- Country marking like “JAPAN”
- Special serial numbers for limited edition models
Once you have the serial number, you can check it against Casio’s official database to see whether it’s an authentic model or not. Missing or generic serial numbers may indicate a fake.
3. Build Quality
Real vintage Casios feel solid and well-made, even the resin models. They shouldn’t feel lightweight or flimsy. Pay attention to the case quality, button feel, and how precisely the case back fits.
Also, case edges should be smooth, not rough, and the screws on the back case must be blunt, not pointed.
4. Model Functions
Another quick test to authenticate a model is to check its functions. Since different models offer different functions, like a calculator, alarms, a stopwatch, a timer, etc., missing a feature or two likely indicates a fake.
For example, if you don’t see the electro-luminescent (EL) display in the classic Casio A168W model or a built-in 8-digit calculator in the Casio CA-53W model, these are likely fakes.
So, make sure to learn about all the important advertised features of the specific Casio model and check those functions in the piece you have (or you want to buy). Usually, fake watches just have buttons that don’t do anything.
5. Display Quality
Real Casio displays stay readable from weird angles. Hold the watch up and tilt it around. You should still be able to read the time. Fake displays often become illegible when viewed from the side.
In models with a backlight feature, the backlight should illuminate evenly, with no dark spots or dim areas.
6. Strap Material & Quality
The straps of vintage Casio watches also feel quite different. For example, real Casio straps have a specific texture and weight. Most vintage models used polyurethane elastomer, which feels flexible but still substantial. Metal bracelets also feel quite solid and substantial, unlike cheaper remakes.
Besides, many original Casio straps may show some tiny markings pressed into them, like “Casio” or material codes like “>PUR<” for polyurethane. The buckle or clasp may also should clean Casio branding.
Lastly, each Casio model was designed with a specific strap. The color, material, and style should make sense for that particular watch. Fake straps often don’t quite fit right; the holes might be wrong sizes or the pins might be loose.
7. Box & Packaging
Another reliable way of verifying a vintage Casio is via its original box, packaging, tags, and manual, as these things prove authenticity. But it’s just that, even the quality of the box is a major clue.
Real Casio packaging feels solid; the cardboard is thick, and the printing on it is also sharp. Replica or mismatched boxes are flimsy and appear fuzzy at the edges.
Most importantly, model numbers on the box should be the same as the number that is engraved at the back of the watch and the manual. Any unmatched details, and you know it isn’t a real deal.
How to Know If Your Casio Is Worth Money? (5 Factors)
Identifying a real vintage Casio is okay, but you must understand that not all vintage Casios are worth equal. Some may fetch five bucks at a garage sale, while others may sell for up to five figures in an auction.
The real value of an old vintage Casio watch depends on the following factors:
1. Model Rarity
Just like many other antiques, rarity majorly drives the value of a vintage Casio. The fewer they made, the more it’s worth today. So, limited editions, discontinued models, and Casios with short production runs command the highest prices today.
Some models had tiny production numbers because they were too weird or too expensive when new. The Casio PELA “paper watch” from 1985 was crazy thin, only 3.9mm tall. It bombed commercially, but now collectors fight over them.
Watches tied to specific events or cultural moments also score big. The F-100 that Sigourney Weaver wore in Alien? People go crazy for it now.
2. Age & Historical Importance
Generally, the older Casio models are way more valuable than the later ones. However, some later models can also fetch exceptional prices if they belong to a limited edition or commemorative edition series.
Besides, the first models in any category are gold mines, like the original Casiotron, the first calculator watch, or the first G-Shock. The first or older models of any line are generally greatly sought after, fetching thousands.
3. Originality
Collectors love vintage watches for their unique mechanisms with all the original parts. Replaced straps, aftermarket crystals, or modified cases kill value. Even using genuine Casio replacement parts hurts collectibility.
The display is especially important in this case. LCD screens can get “digit rot,” where numbers fade or disappear. These are nearly impossible to fix properly. So, if you find a relatively newer display with a very worn-out case, it’s a red flag.
4. Condition & Functionality
Needless to say, vintage Casios in pristine condition are usually worth the most, because watches that are never worn and are still in original packaging (New Old Stock) are what every collector wants.
Slight wear and usage signs are fine (if the model is exceptionally rare), but deep scratches, dings, or broken displays, broken straps, or poorly done repairs drastically reduce value.
Besides, functionality is a major value factor. So, just having all the advertised functions is not enough; every function must operate correctly, too. Because a calculator watch that can’t calculate won’t be worth much.
5. Completeness
Boxes and papers aren’t just for verification; they add a lot to the overall value of a vintage watch. In fact, a complete set can be worth around 30-40% more than just the watch. So, make sure to collect the original documentation, like original receipts, manuals, tags, etc.
