We’re offering a free strap with every Philip Stein watch purchase as a Valentine’s Day special.

Philip Stein watches use natural frequency technology and are so stylish that fans include everyone from Oprah to Rupert Murdoch to Madonna to Samuel L. Jackson. Jet-setting buyers also say the technology has reduced the effects of jet lag when traveling, too.

Here’s what people say about the watches:

“When wearing the watch I experienced drastic changes in both my performance level and energy level.”

“Wearing the watch all day seems to improve my overall peace of mind and mood.”
