Sizing Guide

Need Help Choosing a Case Size?

Here at Vaer our goal is to build watches that can be worn everyday, in all conditions. A critical aspect of longterm wear is comfort and fit. Having a watch that is either too big, or too small can quickly disqualify it from a place in your daily rotation. If you're new to watch case sizing, below is a general overview of the sizes of our 5 core case designs.

If you'd like to read our comprehensive guide to case sizing click here.

Watches are measured by case diameter. This measurement does not include the crown or lugs.

1) 36mm - Smaller Wrists
2) 38mm - Small/Medium Wrists
3) 39mm - Medium Wrists
4) 40mm - Medium Wrists
5) 42mm - Medium/Large Wrists

With that in mind, we've created this case sizing guide to help you choose the watch that is ideal for your particular wrist shape and style preference.

Notes: All Vaer watches are shown on the same 7 inch (177mm) diameter wrist. This is approximately the median wrist size of an adult man. Watches are shown in size from smallest to largest.

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

One of the Best Looking Divers for the Price

"The Vaer D4 Meridian Solar with the blue dial has quickly become a true grab‑and‑go watch for me. The matte ceramic bezel looks fantastic in person, giving it a rugged, premium look without being flashy. This watch looks beautiful, the quality is superb, and it's hard to beat for value. Legibility is excellent in daylight, and the lume really comes alive at night. The solar movement is a huge convenience, with no winding or battery worries. The watch looks great on the bracelet, but it’s also extremely versatile on sailcloth, rubber, nylon, or leather straps. Shipping was quick and straightforward, and the whole buying experience felt smooth and hassle‑free."

The D4 Meridian Navy Matte

"The D4 Meridian Navy Matte Solar is a spectacular watch! As avid watch collectors, we've encountered many timepieces, and this one truly stands out in a crowded marketplace. Its distinctive metal texture, impressive domed crystal, and unique color, combined with reliable solar power and USA assembly, make it a truly exceptional choice."

Brooke V. (5/5)

I am an avid luxury

"I am an avid luxury watch collector and I am proud to own and wear Vaer watches. I am also a veteran and as such cannot pass up the opportunity to support a company working to bring back watch making (assembly) to the US. They make beautiful pieces at an affordable price for every occasion. I am excited to follow this organization… I believe they will continue to do great things-"

Keeps perfect time, love the

"Keeps perfect time, love the solar power, works great in all situations from water sports to the office. Perfect GADA watch. The experience at the Venice store with Ethan was great and would highly recommend going there to try them on before you buy. . . I had several Vaer watches on my radar, but this one just looked and felt right on my wrist."

Jonah R. (5/5)

I love this thing. It's

"I love this thing. It's held up well to the beating all watches take on my wrist. The lum is awesome and remains visible all night. The whole package has a quiet elegance and looks much nicer in person than in the photos. The only improvements I would make would be a black dial while keeping the blue bezel, and making the bezel bidirectional."

Franklin E. (5/5)

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."

My first Vaer watch, and

"My first Vaer watch, and I'm thoroughly impressed. The 39mm fits my 7" wrist perfectly, the dial is clear and easy to read indoors and out, and the matte navy bezel looks great."

Russell V. (5/5)

I really like this watch

"This watch not only looks great but it wears well. The Matte Navy looks fantastic with the black rubber strap. I’m probably going to buy the Jubilee Band for an extra look. Vaer is a great addition to my collection."

Paul K. (5/5)

You don’t have to dive for treasure in the sea…

"Seriously. The title says it all. You cannot find a better watch for the price. If I had a dollar for every person that asked me what I’m wearing on my wrist, I could fill one of those pirate chests."

Kevin O. (5/5)

Aspiring to greatness, but not there yet

"The watch is the perfect size. Vaer appears to have fixed the second-hand issue so it now hits all the markers with each tick, which is much appreciated. And unlike Seiko, their bezel lines up perfectly. What I didn't like, however, was how incredibly stiff the bezel was to rotate. It required some WD-40 and about half an hour of constant rotation to have to work properly. Additionally, the beveled lugs were quite sharp and needed the attention of a high-grit nail file to make them smooth to the touch. And lastly, Vaer doesn't include a shorter length strap option with their watch. I have smaller wrists, so their straps were useless for me. The watch does look nice on the wrist and appears to keep good time. Just wish it didn't require so much after-purchase attention to make it worth the money."
