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.

Description

SUMMARY: The C5 Field Black is a military-inspired 10ATM watch, that stands out in the Vaer line-up thanks to its classic field watch design and the distinction of being the longest selling product (first launched in 2018). As a C5 model, this watch is part of our all-time bestselling collection, distinguished by its ocean-ready functionality, low-profile case design, now featuring the ultra-accurate American-assembled Ameriquartz movement, and full USA assembly.

WHO IS THIS WATCH FOR? We recommend the C5 for those seeking a dependable tool watch that can also be dressed up for more formal occasions. The "set-it-and-forget-it" nature of quartz makes it the perfect fit for an everyday wearer, and the 40mm case sizing is large enough to command presence on most men's wrists while still maintaining our commitment to ergonomic, and timeless proportions.

INSPIRATION In designing the C5 Field Black our goal was to deliver the perfect modern field watch, something that was modern, legible, and with a sensible splash of color. This watch was our first-ever field watch - and its continual re-stocks, provide evidence of a winning formula. In many ways, the C5 Field forms the foundation of our tool watch collection and is a great option for someone starting a new collection, or looking to simplify the information on their wrist.

Sizing and Fit

This watch is sized at 40mm in diameter, and measures 48mm from lug to lug, giving it a medium-sized presence on the wrist, and complementing most men's wrists. The 40mm case is our most popular size, and we recommend it for anyone with wrists in the 6.5 inch to 8.5-inch range, or especially if you're someone who likes a bit more presence on their wrist (compared to our ultra-compact 36mm watches).

Built for extended outdoor use, this watch has been designed to be slim, lightweight, and as comfortable as possible, while still maintaining 10ATM water resistance. The watch case measures 9.4mm in height and has a case weight of 54 grams. The entire case is also rounded and ergonomic so it can be worn comfortably during activities like surfing or mountain biking.

This watch comes in a range of interchangeable strap options, and they are designed to fit wrists ranging from 6.4" to 8.5" in diameter - though we do have specialty straps available for those with wrists outside of this range.

The Perfect Everyday Watch

Leaving on a trip with only one watch? This would be it. Durable and elegant, accurate and affordable, the C5 has everything you need, and nothing you don't. Best of all, it's a great conversation starter - thanks to its unique characteristic of full USA assembly.

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.

Watches for Every Budget
