The 51-30 is a classic piece. Rotating bezel, 3 handed Swiss quartz movement, and waterproof up to 300 meters. But what if you're not heading out on the town? What if you're going surfing, climbing some rocks or something else equally awesome? If that's the case, then you need rubber, son! All the classic styling and features of the 51-30, now with a bombproof, scratchproof rubber casing and band. Oh snap, there's even a tide dial, so you can take this little guy to the tide pools or hunting for mussels! Get some Chorizo up in there and not only do you have a classy timepiece, you've also got a bangin' dinner. Thank you Nixon.
