Welcome to Deep Dive, in which we test dive watches both new and vintage beneath the waves in some of the world’s most beautiful locations. This time, we’re in Bermuda with the classic Seiko SKX007.
Though the Seiko SKX007 has received countless write-ups, I’ve yet to find much about actually SCUBA diving with it. And why bother? Hardly any divers these days wear mechanical watches underwater, let alone rely on them. Alas, digital dive computers have relegated our beloved analog dive watches to the lowly status of lifestyle accessory.
Still, many of our favorite dive watches — the SKX007 included — were meant for use as serious underwater tools, and diving with them reveals aspects of their functional design that remain invisible here on terra firma. I took my SKX007 underwater in Bermuda recently to get a fresh perspective on this old friend.
Introduced in 1996, the SKX007 emerged as the SCUBA industry was still transitioning to digital dive computers, such that Seiko earnestly intended the SKX007 to function as a professional tool. At 42.5mm across, 46mm long, and a beefy 13.5mm thick, the watch feels ultra-capable on-wrist. With 200 meters of water resistance, undeniable legibility, a solid uni-directional timing bezel, a heavily guarded screwed-in crown at four o’clock, and a solid case back, the SKX007 is one of the most reliable and rugged divers Seiko has ever issued. Factor in its sub-$200 US price, and its value was, and still is, undeniable.

When I got to the dive boat in Bermuda’s Grotto Bay, I started yammering about taking photos of watches, and to my surprise two total strangers showed unprecedented interest. Turns out these college-aged twins, Aiden and Isabelle, knew about and loved watches, especially dive watches. Aiden’s eyes widened when I unraveled my watch roll, so I instantly offered him the SKX007 for our dive to the WWII-era Pelanaion wreck; in turn, his sister Isabelle dove with it on our second dive to the coral reef site called The Cathedral.
Having others dive with the SKX007 wasn’t my initial plan, of course, but it gave me an opportunity to photograph and observe the watch from an interesting perspective. Diving more or less side-by-side with Isabelle as we made our way through The Cathedral, I saw the SKX007 gleaming in the filtered blue light of coral canyons, and I saw its Lumibright markers and hands maintain bold legibility as we descended into dark tunnels. Of all the watches I’ve taken diving, the SKX007 handily won the legibility contest, and all the fussing over aesthetic minutiae that I so readily engage in on land gave way to a blunt appreciation for the fact that Seiko designed the SKX007 for one purpose: SCUBA diving.
