How do you say 'I love you' to an enginerd? To a fan of Sylar on Heroes? With cogs and gears, apparently.
As Uncrate points out, Red Envelope is offering these watch gear cufflinks for $125. They are an alternative, I suppose, to the silver baubles already offered by a certain company with a signature blue box.

Forget the bolt-shaped cufflinks and wow him or her with "antique watch works." (Yes, women wear French cuffs, too.)
Red Envelope says that ordering by February 7 with only ground shipping will still get them there by Valentine's Day.
Many of us over here, actually, loved these things. But as one co-worker pointed out, they probably don't look so great with a sweatshirt. So unless you're willing to invest in the Pinks to go with them, a red cell phone or colorful iPod shuffle packed with "your" songs might be the better way to go.
Whatever you do, just don't get this.
