"Vaer is guiding people toward an enthusiast design language in a way we haven't seen before."

- Hodinkee

"Few 20ATM automatic divers are assembled in the States. A sleek design—classic dive-watch bezel, see-through case back, luminous minute markers—put it over the top."

Perpetual Accuracy,
For All Conditions

The Vaer D4 Solar Diver combines everything we’ve learned in the past 5 years into a single all-purpose tool watch - blending the top grade specs of our popular mechanical Dive Watches with the affordability and everyday utility of our USA assembled quartz models.


Water Resistance Rating

All Vaer watches are ocean-ready. The D4 goes to the limits of real-world depth exposure.


Domed Crystal

The D4 features a scratch resistant double domed top crystal, and a deep-etched caseback.


Assembly and Testing

The D4 is assembled and tested in America - and includes our standard Guaranteed Waterproof Warranty.

Guaranteed Waterproof

20ATM tested with a locking crown

Vaer has always been an ocean-based brand. Headquartered half a mile from the Pacific coastline, we view water resistance not merely as a hypothetical "nice-to-have," but as a functional everyday necessity. While the locking10ATM rating on most of our watch line-up covers 95% of in-water use cases, our Diver models go a step above. At 20ATM this watch will cover all real-world depth exposures, while maintaining a slim and elegant case profile and a comfortable on-wrist experience in all conditions, including over and under a wetsuit.

2x Easy Change Straps

Endless Customization with Extra Straps

The D4 collection offers a range of customization, not only offering 3 distinctive dial designs, but also a full lineup of our 20mm interchangeable straps. All D4 watches come standard with a comfortable and functional quick-release tropic strap and a 2nd strap of your choice. These options include our USA-made Horween leather straps, our premium quick release steel bracelet, and a range of ocean-ready nylon designs. To add even more functionality to your watch, you can also bundle a 3rd strap of your choice, from our full range of color combinations.

Assembled in the USA

An investment in American craftsmanship

Your daily wristwatch is an incredibly important and personal object, and we think you should have a choice of where it's put together. While we do offer the choice of Swiss and Asian assembly, our core offering is USA assembly by our team of technicians. The D4 line is powered by a best-in-class Japanese made Epson VS22 Solar movement, which can be powered perpetually by sunlight, lamp light, or even a candle. For details on charging times, please refer to our in-depth design review video.

Powered by Light

Sunlight will keep the D4 on-time perpetually

The Vaer D4 Diver balances the accuracy of quartz with the perpetual power of an automatic. Utilizing a small solar cell hidden beneath the dial, 6 hours of sunlight will keep the watch going for 6 months in darkness. Stuck in the office? Regular exposure to a light source as weak as a fluorescent lamp will also keep the watch going for months on end - that said, we firmly believe this watch is best enjoyed in it's natural environment - the great outdoors.
