It’s hard to believe, but it’s been over 8 years now since the first Oris Depth Gauge was released (we covered it here). And actually, if you’re not familiar with the concept of how this watch works, that article does a good high-level summary, including explaining what Boyle’s law is. So, what does this new Oris Depth Gauge have in store?

Unsurprisingly – for a dive watch with an open hole in it – the new Oris Aquis Depth Gauge has had some attention paid to that opening, and the air channel that runs around the dial. Specifically, they focused on the precision that they’re milling that channel, allowing for greater accuracy – and visibility – of the gauge. Secondly, they’ve rotated the meters-to-feet conversion chart on the caseback so it’s at 90 degrees to the 12 o’clock position, making it easier to use.

Finally, the Oris Aquis Depth Gauge has a feature I’m hoping we see in some other Oris models, inside or out of the Aquis range. This is their new quick change strap system. Not that changing straps is difficult, but once you start using those quick change spring bars, they do make life simpler. Now, on a dive watch, you want something a bit more robust. But what if you want to change out the business-ready stainless steel bracelet for dive-ready rubber? That’s where this new connection comes into play. From the drawings I see in the press release, it looks like there’s a small locking clasp on the center link that (presumably) goes around the lug bar and holds tightly in place.

As with the previous Oris Aquis Depth Gauge, this is a watch meant for folks who will actually take it diving and make use of that depth gauge. I mean, sure, you could buy it an never use that function, but where’s the fun in that? Whatever your reason, you can pick one up for $4,100 – me, I’ll wait for the quick change system to move out into other parts of the collection.
