All functions work properly including the light, the sound, and the temperature.

There is one light scratch on the glass (not deep, not cracked glass).

The strap is new and original Casio, dedicated for this model. I have repaced the strap loop with a non casio one.

It seems that Ayrton Senna had been wearing this model during his first two years in F1 (84-85)

Check out the forum ''watchuseek'', and search for the thread ''which is that watch on ayrton senna wrist''

ans also the website ''liquid crystal'' and search for ''Casio ts-1000''

Ebay wont let me add the links...
