Hopeful new father needs a logo for a niche business

BPH, Beats per Hour

BPH (which stands for Beats per Hour) is a new online retailer that specializes in high end, edgy, sophisticated and fashionable Japanese domestic market timepieces that were not previously available in US markets. Our time pieces ranges from US$300 to US$10,000. We're looking for a logo that will work well with both white or black backgrounds, and an icon that can be used for Facebook, Twitter, and in mobile app stores.

Our target customer is young (18-35), affluent, fashion forward, and tech savvy. They are connoisseurs of fashion and experts in horological technologies.

Require:
-High resolution graphics with original layered file or graphics with transparent background
-A logo that works for both black and white backgrounds. Perhaps 2 versions of the same logo with slight color differences to account for the background color change
-A logo that works for the online storefront, letterheads, receipts, business cards, and small packages.
-A square icon that can be used for twitter, facebook, app. We prefer something shaded with depth, eg. Google Chrome, Blackberry Messenger, etc.
-Although we are a watch retailer, we don't really care to have the words "watches" in the logo.

Wish:
A symbol in the logo and the icon that
-incorporates mechanisms of the a watch movement
-expresses the abstract idea in passage of time
-is a easily recognizable symbol

Our wishes are nice to have, not must have. It would be nice to be able to incorporate such elements, but we understand that may not be possible.

The attached file is a zip file of some of the watches we plan to offer. These watches are equipped with movements of quartz precision, but offers the mystique, beauty, and action of purely mechanical watches. Please take a look at them for some idea what we're selling.
