Well, the watch is from an unverified story published on a website known for bullshit, and has never been followed up on in almost a decade. And while the so-called "time-traveling hipster" might look at odds with his surroundings, all of the stuff that he's wearing was commercially available at the time, from the cardigan to the sunglasses all the way down to the tiny camera. Because that's what hipsters do: They dress like your great-grandfather. So how could you possibly tell them apart? Though the idea that someone mastered time travel just to go back and ironically witness the opening of a bridge in British Columbia is perhaps the most hipster thing imaginable.
But to all of us time travel skeptics, true believers have one last ace up their sleeves. Behold, the helicopter hieroglyphs of Abydos! Found in the lost Egyptian Temple of Seti, this series of hieroglyphs clearly show the outline of a helicopter, as well as other examples of modern machinery, such as a submarine and a jet fighter. Proof that's actually set in stone. Pretty damning, right?
Submarine or Luke Skywalker's landspeeder.
Well, according to some academics bored enough to debunk this nonsense, those shapes are just a coincidental side effect of the stone having been reused at some point, with new symbols being carved on top of old ones (this is not uncommon, it turns out). They don't even work as hieroglyphs anymore; only as a Rorschach test for conspiracy theorists. Also, and this is simply our amateur opinion here, if pharaohs really had the choice between taking a cat or an attack helicopter into the afterlife, every Egyptian tomb would look like the "Ride of The Valkyries" scene in Apocalypse Now.
