Question 1

Which Casio Vintage model should I buy first?

Accepted Answer

If a crisp readout and roughly seven-year battery matter most, the F-91W or the steel-bracelet A158 are ideal. Want a better backlight and a slightly larger case? The 2001 A168 is the pick. All sit between $20 and $30, so there is no wrong choice here.

Question 2

What is the difference between the F-91W and the A158?

Accepted Answer

Both share the same square digital layout. The F-91W uses a resin case and strap at around $20, lighter and more sporty. The A158 wraps that same brain in a steel case and bracelet near $25, giving you a more metallic, dressier feel on the wrist.

Question 3

Are Casio Vintage watches water resistant?

Accepted Answer

These models are splash-resistant, so handwashing, rain, and sweat are fine. They are not designed for swimming, showering, or diving. Avoid pressing the buttons underwater and keep them out of forceful jets, but for everyday wear you can put one on without worry.

Question 4

Is the battery expensive to replace?

Accepted Answer

No, this is the easiest part of ownership. The models run on a CR2016 cell that costs only a few dollars. Most jewelers swap it in minutes, or you can open the caseback and fit it yourself. There is no meaningful service cost to budget for.

Question 5

Do Casio Vintage watches hold value or make a good investment?

Accepted Answer

No, these are not investment pieces and you should not treat them that way. There is no waitlist and no secondary-market premium. Their value lies in use and reliability rather than money: you are buying an honest tool you can wear daily and replace cheaply if it breaks.
