Both of these are cheap Casios with a world map display and World Time function, but they’re built for genuinely different people. The A500 is the slimmer, dressier vintage option with a steel bracelet. The AE1200 — the one enthusiasts nicknamed “Casio Royale” — is the chunkier, more practical travel watch with real water resistance and a battery that outlasts the A500’s by years, not months.
Short version: buy the A500 if you want a clean metal-bracelet vintage Casio that happens to have World Time. Buy the AE1200 if you actually want the better watch to travel with, swim with, and forget about for a decade. Buying with your eyes, it’s the A500. Buying with your head, it’s the AE1200 — and it’s not especially close.

Design: The Actual Reason to Want the A500
The A500 earns its appeal here, no argument. It’s slimmer, sits closer to the classic Casio Vintage silhouette, and the stainless steel bracelet gives it a dressy-casual quality the AE1200 simply doesn’t have — it looks like a watch first and a travel gadget second, which is exactly the opposite of the AE1200’s whole personality. If you want something that reads as a genuine accessory rather than a tool strapped to your wrist, this is the entire case for the A500 in one paragraph.
The AE1200 leans hard into looking like what it is: a busy, multi-window travel instrument. That’s not a knock — it’s the point. The world map display and layout give it real retro-gadget charm, but nobody’s mistaking it for a dress watch.
Comfort Depends Heavily on Which AE1200 You’re Comparing
The A500’s smaller 39 x 34 x 9.6mm case genuinely wears easier on a small wrist and slips under a sleeve without a fight — advantage A500, straightforwardly.
Where it gets more complicated is the AE1200, because “the AE1200” isn’t one weight. The resin-strap version is actually lighter than the A500 at around 39g, despite the visibly larger case — light plastic construction does a lot of work there. The steel-bracelet AE1200, on the other hand, jumps to roughly 91g, nearly double the A500’s weight. If you’re comparing the A500 against a resin AE1200, comfort is genuinely a wash depending on what you value; against the steel AE1200, the A500 wins outright on wearability.
Where the AE1200 Stops Being a Contest
A few categories here aren’t close enough to frame as a genuine debate.
Water resistance is the biggest one. The A500 carries a basic Water Resistant rating — fine for rain and hand-washing, not something I’d trust in a pool. The AE1200’s 100m rating means you don’t have to think about it near water at all. That’s not a marginal edge; it changes what kind of watch you can actually rely on day to day.
Battery life tells a similar story. The A500’s CR1616 is rated for roughly three years; the AE1200’s CR2025 is rated for about ten. That’s the difference between opening the case back every few years versus roughly once a decade — a genuinely large gap in maintenance for two watches in the same price range.
Travel practicality follows directly from both of the above, plus a larger, easier-to-read World Time layout on the AE1200. The A500 has the same underlying World Time function, but the smaller display and more delicate presentation make it feel more like a style statement that happens to show other time zones than a watch built specifically for travel.
Durability and the Community Around Each Watch
Neither of these is remotely a G-Shock, so treat “durability” here as relative. The A500’s chrome-plated resin case looks sharp out of the box, but that shine is also the first thing to show scuffs over time. The AE1200’s resin case is less flashy but reads as more of an honest daily beater — nothing precious about it, and it’s cheap and easy to replace if it does get damaged.
Worth mentioning: the AE1200 has built up a genuinely active modding and enthusiast community — people swapping straps, cases, and display details on it in a way the A500 hasn’t really attracted. If tinkering with a cheap watch appeals to you, that’s a real point in the AE1200’s favor beyond the spec sheet.
Water Resistance, Side by Side
| Situation | Casio A500 | Casio AE1200 |
|---|---|---|
| Rain | Fine | Fine |
| Hand washing | Fine | Fine |
| Sweat / light splashes | Fine | Fine |
| Shower | Not recommended | Generally fine, avoid soap buildup |
| Swimming | Not recommended | Yes |
| Snorkeling | No | Yes, within reason |
| Diving | No | No |
The takeaway is simple: if there’s any real chance this watch ends up near a pool or the ocean, the A500 isn’t the right tool for that, and the AE1200 is.
Price and Value
The AE1200 is the better value by almost any measure that isn’t purely aesthetic — 100m water resistance, a decade of battery life, and a larger, more usable display, all for a similar price point to the A500. The A500 isn’t a bad buy, but you’re explicitly paying for the slimmer metal-bracelet look rather than for anything it does better functionally.

Which One Should You Actually Buy
Go with the A500 if you specifically want a slim, bracelet-style vintage Casio and you’re fine treating World Time as a nice extra rather than a feature you’ll lean on — this is a style purchase first.
Go with the AE1200 if you actually travel, want real water confidence, or just don’t want to think about the battery again for a decade. For most people asking “which world time Casio should I buy,” this is the more defensible answer.
A Few Other Options Worth Knowing
If the countdown/interval timer matters more to you than the AE1200’s base feature set, the AE1300 is worth a look. Want the A500’s slim vintage feel without the World Time function at all? The A700 covers that. If you’d rather have a simpler display alongside the same 100m water resistance, the W800H is a solid alternative to the AE1200. And if durability is the actual priority over anything discussed here, a G-Shock DW-5600 or GW-M5610U solves that outright — neither the A500 nor the AE1200 is really competing in that category.
Bottom Line
The A500 wins on looks and nothing else, and it wins there clearly — if a slim, bracelet-style vintage Casio with World Time charm is what you want, it delivers exactly that. The AE1200 wins everywhere else that actually matters day to day: water resistance, battery life, display usability, and overall value. Unless the A500’s specific look is genuinely the deciding factor for you, the AE1200 is the watch most people should actually buy.
FAQ
Is the A500 better than the AE1200? For style, yes. For practicality — water resistance, battery life, everyday usability — the AE1200 is clearly ahead.
Which has the better battery life? The AE1200, by a wide margin — around 10 years versus the A500’s roughly 3.
Can you swim with the A500? No, not safely. It carries only a basic Water Resistant rating, meant for rain and splashes rather than submersion.
Can you swim with the AE1200? Yes — its 100m rating covers swimming comfortably, though it’s still worth avoiding soap and very hot water, which can degrade the seals over time.
Which is better for a small wrist? The A500, thanks to its smaller, thinner case.
Which is the better travel watch? The AE1200, without much debate — 100m water resistance, a decade of battery life, and a larger World Time display all point the same direction.
Does the A500 actually have a world map display? Yes — it includes both World Time and a world map, the same core feature as the AE1200, just presented in a smaller, dressier package.
Which should I buy first if I want both eventually? Start with the AE1200 if practicality matters more to you right now; start with the A500 if you specifically want that slim vintage bracelet look and can accept its water-resistance and battery limitations.
