Chk out Ventura.ch watches. Pricey, company I believe under new ownership. John McLaughlin ( political pundit ) wears one. No calendar but day/date. Very nice unique.
There is at least one American distributor that sells digital, battery powered very unique/artsy watches - some which have unusual functions.

Ayrton Senna when he raced for Toleman wore a calculator watch - that's why I think about getting a Casio Calculator watch - geeky high fashion
