Well dilphinus... if you are looking for a unique watch to match certain occasions and not a daily beater
then you can check out this website
Cool Watches, Unique Watches, Unusual Watches, Modern Watches
Not too sure if it has crossed your screen before
+ 1 for this website for u to assess your "taste" of unique design watch. Designer also many types and varied preferences. Some minimalist, some loud, some techie. What are u?
To re-cap your criteria so far: leather strap, ladies watch, for petite frame,
unique to match your designer image
IMHO, at your budget of $2-3K, it's not possible to get unique, special design watches (whatever that means to u, entirely subjective) that is worth that money. Not making it easy either when u say that larger watches are not suitable, because the so-called "special design" watches these days are typically large dial (seven friday, bell and ross etc). If skeleton is your thing, can try ORIS.
But i personally think u r better off looking at swatch or bugis village, cineleisure shops or the website mentioned for the unique piece that u feel can match your image and save the $ for travelling.
