Mary Kate and Ashley Olsen have more than proven they’ve got major fashion chops, having successfully transformed their images beyond the Michelle Tanner era into bona fide designers. They’ve built a style empire, with their Elizabeth and James collection a favorite among the It-girl crowd for its minimalist clothing and accessories. So needless to say, when the label announced the launch of their new 200 Series watch collection, our ears perked all the way up.

What we love about the 200 Series is how it mixes retro and modern vibes. In true Olsen style, the watch is inspired by the ’70s — or rather, the digital LED technology first founded way back when. The strap is formulated with rubber and features a mirrored mineral crystal face, meaning when the time display is off (just the press of a button), you can use the watch as an impromptu mirror for quick checks. Um, yes. “The 200 SERIES captures our shared nostalgia for the watches from our youth but reimagined in a sleek design,” explains Mary Kate Olsen. Because who doesn’t want to recapture a little of their childhood?

You can cop the 200 Series watch in any of five mirrored metallic colorways including Silver, Gunmetal, Sky, Chartreuse, and Royal, with a white or black strap, for $200 at Casual and cool, this is bound to be your new everyday favorite, not to mention a stylish substitute for your phone. It’s about time.
