The CASIO Collection — Beautifully retro
The cult following for the shape, function and colour of the first CASIO digital watch from the 1980s is more up-to-date than ever thanks to the watches in the retro Collection. With warm shades of gold, cool stainless steel and black plastic, these timeless design icons can be combined perfectly with modern style. It's good to know that some things never change.

Display illumination
The watch dial or display illuminates at the touch of a button, helping you to see everything, even in absolute darkness.

Alarm Function
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set.

Waterproof up to 5 bar
Taking a shower or bath with this watch is not a problem. It has been tested for water resistance up to 5 bar/50 metres.
Product description
Casio's definitive retro watch in rose gold, featuring LED light, stopwatch and 50 m water resistance.

- Reviewed in Canada on April 18, 2016Verified PurchasePerfect watch for me, I love it, fits just right with my skintone. Came packed very well, with a tin box. After a month of wear, it did get a tiny scratch on the bottom, it is black underneath the rose gold. I had trouble adjusting the band at first but quickly got the hang of it. It came very fast and would recommend it to everyone thinking to buy it.

5.0 out of 5 stars Product arrived exactly as described.
Verified PurchaseVery happy with watch.
Would buy again.
Not a small ladies watch, Ideal if your looking for something not so dainty. Very happy with colour, and comfortable enough to wear all day.
