Selling my CASIO C-801 which is great working condition and is in all original condition. 


Every button works including all the functions and has a nice strong backlight. 

Use the photos as part of the description and condition. 

Crystal is in great shape.

LCD works perfectly with no missing digits... some rainbow is seen, but doesn't effect the LCD visibility. 

As mentioned the backlight is really good and strong. 

All keypad buttons work freely upon touch. There is a mark on the keypad which can be viewed in the photos.

The case is brass with chrome plating, and does have some marks on the underside, but looks worse on camera. 

Bracelet is complete and the clasp fixes firmly. Made in Japan is stamped. 

Both batteries have been replaced quite recently using RENATA. 

For the age this C-801 is in really good working condition.

Will include the instructions on how to use, and this is more towards setting the time/date (Module 133)

Also there are websites that show which calendar years are repeated, so at the moment it's set with 1999

And for fun will include some fun with numbers to create 251 words like my example with BLISS 


Any questions please don't hesitate to ask. 


Thank you
