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.

Strap Sizing Guide

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.

Two Straps Standard

Our 20mm straps are interchangeable

The C4 Tactical is the toughest, most functional watch Vaer has ever built — a solar-powered, bead-blasted tool watch designed with direct input from active-duty military operators.

Why we love it

The C4 Tactical was born from the field. Over years of working with service members and first responders, we heard one consistent message: comfort, reliability, and legibility matter more than anything else. Drawing inspiration from the watches issued to Navy SEALs and Special Forces in the 1970s — the C4 carries that same stripped-down, function-first ethos into the modern era. Every detail was considered: a bead-blasted case to eliminate reflections, oversized 3D Super-LumiNova blocks, and a recessed 4 o’clock crown that disappears during wear. Unlike the mechanical watches of the past, the C4 runs on a solar movement — delivering absolute accuracy with zero battery maintenance.

Our success has been built on delivering exceptional value to our owners.

The Perfect Everyday Watch

Headed into the field with only one watch? This would be it. The C4 Tactical is mission-ready — engineered with 200m water resistance, reinforced shock protection, and a solar-powered movement that runs off any light source. Built to take abuse, it delivers absolute accuracy and rugged dependability in combat conditions.

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

Lume was as good as

"Lume was as good as I expected if not better. I have been wearing daily, climbing ladders, knocking it against walls, scraping metal and rocks. Not even a smidge or scratch mark anywhere. Both straps are comfortable and I love the army green nato instead of the khaki most models come with. My only recommendation for this model specifically is a date window. I am already planning my next Vaer purchase, I need at least one of each style lol! D4 meridian navy looks soo classy! My only recommendation for Vaer is opt for USA assembled models. As far as the specs go on the website the non USA assembled models don’t have the same level of lume and bezel inserts material can be different. It’s worth the extra few dollars to get the USA assembled models, I wish they highlighted that on the website because I was tempted to get the cheaper models."

Christopher R. (5/5)

"Honestly, I was initially disappointed in the size if the C4 on my wrist. I am a large human and it just looked too small. And then I wore it for a week. It is sized perfectly to see and it slides in and out if my pockets how I prefer. Quality construction. Beautiful design. I will be buying more Vaer inbthe future."

Matthew (5/5)

Awesome Watch!!!!

"This is a really great piece. Order was shipped quickly and arrived in perfect condition. I really like the fact it doesn't have a date window and the 3D printed lume blocks really pop. This will be my new daily. Ryan and Reagan keep up the good work and ignore the haters."

Nathaniel S. (5/5)

The C4 is my second

"The C4 is my second Vaer. It will not be my last. I have everything from Rolex's, Tudors, Tags, Omega and such. I like to blend in some nice American "do it all" watches and Vaer nailed that well. A solid well built semi casual watch that I will gladly use while wearing a suit too. They are a good price point too."

William P. (5/5)

Please make a Day-Date version

"Solar-powered, Quartz, diver-capable, 200m. Not over-sized. Affordable. Dependable. Find the strap you love to make it your own (for me a Gray, rubber CrafterBlue UX03). If VAER makes this EXACT watch, but with a Day-Date complication, they’ll break the Internet."
