Need help choosing your straps?

One of the most rewarding aspects of owning a watch is the opportunity for customize your straps. In addition to adding a unique personality to your timepiece, changing your straps is a great way to increase a watches value and functionality. Here at Vaer, every watch we sell comes with your choice to 2x quick change straps.

In addition to a comfortable Primary Strap made for in-water functionality, we allow you to choose from a wide range of Secondary Straps to suit a variety of functions and styles.

Because different straps have different manufacturing costs your choice of Secondary Strap will be reflected in the watch's final retail cost. All strap options can also be purchased individually if you're interesting in buying a third, or fourth strap.

Note: All Vaer watch straps are sized for 20mm lugs and are cross compatible between models. Vaer bracelets are custom fitted and are NOT cross compatible.

The Perfect Everyday Watch

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.

1. Ocean-Ready

Life is unpredictable. The perfect everyday watch needs to provide peace of mind in all conditions. Whether you're heading out in the rain or taking a jump in the pool, this watch never needs to be left on the sidelines.

2. Scratch Resistant

Impact is inevitable. When it happens, you want to be sure your watch won't scratch. That's why we use premium sapphire crystal to protect our dials (the second hardest material after diamond).

3. Easy Customization

Every day is different. And the easiest way to switch up the look (and functionality) of your watch is to change straps. That's why every Vaer watch ships with 2x quick-change strap options.

Reviews

Really unfortunate experience with this

"Really unfortunate experience with this watch but it was mostly the jubilee bracelet & clasp. The locking mechanism didn’t properly close on one side and the pins on the quick release were defective and the watch fell off my hand 3-5 times in one day. It appeared as if the quick release pin was too short and didn’t go all the way in the dial hole. I switched to the black rubber strap it came with and it didn’t have that issue. The real problem I had was with customer service. Took me two weeks to get a reply and the reply didn’t hit both issues. It was clear the person that reached out skimmed my email inquiry. It was another week after that before I heard from someone. I also paid the $11 for “expedited shipping, returns, and exchanges” and it was anything but expedited. The watch was fine, a little small but that was expected. I was really let down by the customer service tbh. I know it’s only a $600 watch but to some people, me included, that’s a lot of money for a watch. And to not be able to wear it on the Jubilee you paid for, for 3 weeks, is unsatisfactory, IMO. That being said, I love my C5 solar and I think it may have just been a bad few weeks at Vaer."

Consumer Review.

"I can honestly say, this is the nicest, and my most favorite watch I own. I have yet to take in in any body of water, as I am afraid to mess it up, but I will once I get over the newness of the purchase. Thus far, it excels in performance! Accurate, functional, and fits my active lifestyle. I ride motorcycles, and the Go Anywhere, Do Anything (GADA) selling point seems to be precise! One, small thing is the watch band I purchased in addition to the rubber or silicone band it comes with, the safety clasp on the metal band seems to pop open/come undone when under the slightest tension. I reached out to the company, and they sent me a video on how to adjust the clasp to prevent it from unexpectedly opening. My biggest fear with an expensive watch purchase is the band won't hold, and it slips off during an activity, and the watch is either broken from the fall, or lost forever. The adjustment was simple and rudimentary, so no issues since then with the safety clasp, and sizing the band was simple to do, IF you have the proper sized tools for the job to remove the necessary links, and micro adjustment to perfectly fit your wrist. Overall, I'm happy with this watch, and believe it will serve it's purpose for a long time!"

VAER D4 Outerknown

"This is what I call an outstanding brand experience, as a first time buyer all I can say is that VAER is an amazing brand, I live in Portugal and it has arrived in 5 days, and the watch is a masterpiece! The 39mm fits perfectly not too big, not too small just perfect! A very well built watch. As a fan of Outerknown now I'm also a fan of VAER, the watch is just Awesome! Thank ou VAER, Keep rocking! Recomend 100%"

Bruno (5/5)

The watch itself was awesome.

"The watch itself was awesome. Personally I didn't like the look of the light blue on the bezel in person so I returned it. If it was solid dark blue I would have definitely kept it. Im waiting till their blue or black 39mm divers come back in stock as I cant stop thinking about the watch. Hopefully they will have a black dial blue bezel combo but I doubt it. If you like the look of the bezel I'd recommend it."

Franklin E. (4/5)

Very pleased with this version

"Very pleased with this version of the D4, the first time I've added a solar analog watch to my collection, & there really isn't a better entry point for that style of diver. Sizing is of course variable relative to your wrist size, but Vaer's 39mm case is competitive with anything on the market - great design, the twisted-downward lugs, exceptionally comfortable on most wrists I'd imagine. Excellent bezel action. The Outerknown collab is worth it for the stylish caseback, & the bracelet is well-built with tight tolerances. This will get plenty of wear. Very much worth looking into, to see exactly the value that's possible from a microbrand."

Trevor R. (5/5)

I already own a D5

"I already own a D5 and a D7, and thisnis a nice addition to the collection. I bought this because I really wanted a solar watch that I didn't have to wind and reset the time on whenever I would put it on. Overall quality is nice and I like the unique bezel color combo that this collaboration provided. That said, I don't like the look of the completely smooth and shiny bezel this has, compared to the D5 & D7 that have the numbers engraved in them. Overall, it's a very nice watch of high quality, particularly at this price point."

Douglas H. (5/5)

Super High Quality All Around

"I’m so impressed by my new Vaer D4. Not only is it a beautiful watch to look at, the fit and finish are leagues better than anything at this price point. I can’t wait to score something else from Vaer, looking forward to some restocks."

Tyler A. (5/5)

Very nice, stylish watch. Only

"Very nice, stylish watch. Only complaint is the lume is not very bright at all, harder to read in low light than any other dive watch I’ve owned. Also wish they had more stripe straps."
