Hi there,
It may be more helpful to identify any particular characteristics of the watch that appeal to your girlfriend. I can't tell much about the dial except it has full arabics and may be a two-tone watch (or not) with a gold dial. I spent 10 minutes looking through pics of her online and it seems she wears several watches and I saw one that looked all gold, though I didn't personally focus on that aspect so much as more the general style of case and bracelet combination. I found the following few that may be promising out of 6,000 or more ladies watches on overstock, amazon, and general google image searches. I'm not sure if any of this will help if it must be that watch, but these are marginally close. Thanks for the challenge. I'm sorry I failed to find a 100% match.
Regards,
Jeff
Edit: I took a look at Tissot, Hamilton, Anne Klein, Armani, Seiko, and Citizen and found some that were similar to those below, but not enough to also post them here.
and this was a Frederique Constant from amazon....
Something called AIBI....also from Amazon
