This article provides a comprehensive overview of the Vaer D4 & DS4 Solar Dive watches and a comparison between the two models.
We launched our first dive watch back in 2020, and followed up that success with our first solar dive watch in the summer of 2021. Since then we’ve continued to expand and evolve our solar dive collection in a range of models, sizes, and color-ways. Across the solar dive collection you can expect 8 key features:
- 20ATM Water Resistance - Professional dive rating.
- Perpetual Off-Grid accuracy - Robust solar movement.
- Scratch-Resistant Sapphire - Protection from impact.
- BGW9 Super-Luminova - Brilliant deep water glow.
- Deep Etched Caseback - Strong aesthetics, front and back.
- Two Easy-Change Straps - For extreme versatility.
- Choice of case sizes - 38mm and 42mm
- Option of USA assembly - Our premium D4 model.
If you’re curious to know a little bit more about each of these key features, or want some additional advice on which Solar Dive watch is right for you, scroll below for more details.
I. Solar Dive Watch Feature Summary
1. Ocean Ready - 20ATM Water-Resistance Rating
Dive watches often boast about their water-resistance ratings, but what does a 20ATM rating actually signify? ATM stands for atmospheres, and it represents the depth to which a watch can be submerged without incurring damage. A 20ATM rating means the watch can withstand pressures equivalent to a depth of 200 meters (or roughly 660 feet) underwater.
For the everyday user, this means you don’t have to worry about taking your watch off for a swim, snorkeling adventure, or even most recreational scuba diving activities. Vaer ensures that you're not just wearing a stylish accessory but a robust timepiece that can accompany you in all your aquatic adventures. 
2. Perpetual accuracy - Solar Movements
At the heart of Vaer's Solar Dive Watches lies an innovative solar-powered movement. Unlike traditional quartz watches that rely on disposable batteries, or mechanical watches that require manual winding, a solar watch harnesses the power of light to charge its battery. This means you can wear your watch for longer durations without worrying about battery replacements.
The solar-powered movement not only adds an eco-friendly touch but also ensures that you have a reliable timepiece that requires minimal maintenance. It's a perfect blend of sustainability and modern technology.
a) Perpetual Timekeeping
One of the prime benefits of a solar watch is the perpetual timekeeping it offers. Unlike traditional battery-powered watches, our solar-powered watches harness energy from any light source. This means they continuously recharge, providing you with uninterrupted and accurate timekeeping.
b) Incredible Accuracy
Our solar-powered watches incorporate high-quality quartz movements, known for their superior accuracy. The integration of a quartz crystal regulated by the power generated from light ensures that your watch remains highly precise throughout its lifetime.
c) Quick Charging
Unlike common misconceptions, solar-powered watches do not take long to charge. With the Epson VS-22 or VS-42 movement, it takes just six hours of light exposure to fully charge the watch. That's right – within a single day, your watch can harness enough power to keep running accurately and consistently.
d) Extended Power Reserve
One of the key distinguishing features of our solar watches is their impressive power reserve. Once fully charged, these watches can continue to function accurately for up to six months, even in complete darkness. This makes them an excellent choice for explorers and adventurers who venture into off-grid locations.
e) Versatile Charging in Any Condition
Whether you're under the sun or in the glow of an incandescent bulb, our solar watches can charge in virtually any light condition. This feature provides you with a level of flexibility and independence that is unmatched by battery-powered watches.
3. Impact Protected - Durability of Sapphire Crystal
One of the standout features of Vaer's Solar Dive Watches is their sapphire crystal face. Sapphire, second only to diamond in terms of hardness, ensures that your watch is highly resistant to scratches and abrasions. This means that whether you're navigating through coral reefs or simply brushing against surfaces during everyday wear, the watch face remains clear and pristine.
In addition to its impressive durability, sapphire crystal offers a clear, distortion-free view of the time, making it both a functional and aesthetically pleasing feature.
4. BGW9 Super-Luminova Paint - The Glow in the Dark
One of the challenges divers often face is reading the time in low-light conditions underwater. Vaer's Solar Dive Watches come with a solution – the powerful BGW9 Super-Luminova paint. This paint illuminates the watch hands and markers, offering a bright and long-lasting glow. Whether you're diving during the night or exploring deeper, shadowed waters, the BGW9 Super-Luminova ensures that you can always read the time at a glance.
5. The Deep Etched Steel Caseback - A Mark of Identity
One of the first things that might catch your eye when handling one of Vaer's Solar Dive Watches is the deep etched steel caseback. This isn't just any regular etching – it boasts a textured Vaer logo that stands out in a subtle, yet unmistakable manner. It's a mark of identity, a testament to the brand's commitment to craftsmanship and attention to detail.
6. Interchangeable 20mm Straps – For Added Value
We all love to switch things up a bit. That's why our Solar Dive Watches come with not one, but 2x interchangeable 20mm straps. Whether you're heading for a boardroom meeting or a beach party, switching straps ensures your watch always complements your outfit, and also is perfectly suited to the task at hand. For pure impact and luxury feel, it’s hard to beat the D4 and DS4 diver on our stainless bracelet, for in-water or outdoor use, we have a variety of nylon and rubber straps to ensure all-day on-wrist comfort and feel.
7. Choosing the Right Fit – 38mm vs. 42mm Case
Wrist comfort is critical, and we recognizes that everyone's wrist is unique. So whether you've got a smaller wrist or a bigger one, they've got you covered. Choose the 38mm case for small to medium wrists for a snug fit without looking oversized. For those with larger wrists (e.g. over 7 inches) the 42mm ensures that the watch sits prominently without appearing over-sized or bulky.
8. D4 Solar Diver - Proudly Assembled in the USA
Last but certainly not least, the D4 Solar Diver holds a special designation. It's not just any dive watch; it's the only solar dive watch on the market assembled in the USA. This ensures a level of craftsmanship and attention to detail that's synonymous with American manufacturing. When you wear a Vaer Solar Dive Watch, you're not just wearing a watch, but a statement to American sourcing and ingenuity.
II. Comparing Vaer Solar Divers: D4 vs. DS4
By now, you may have decided that a Vaer Solar Diver is right for you, but let's get down to the specifics of exactly which one is the right match for your wrist, and budget.
The Vaer D4 Solar Diver is our more premium option. Starting at $359, it's not just any watch; it's a unique statement piece assembled right here in the USA. What makes it stand out? In addition to American assembly it also offers domed sapphire crystal (compared to the DS4, which is flat). Domed sapphire is not just striking to look at, but also incredibly durable. Then there’s the optional ceramic 120-click uni-direction bezel – a feature that speaks volumes about the watch's premium build. Finally, greater customization - unlike the DS4 which only has two choices for secondary straps, the D4 has 6 different options.
On the other hand, for those who are looking for an affordable yet quality-packed option, the DS4 Solar Diver is the way to go. Priced at a wallet-friendly $259, it comes with flat sapphire, ensuring that while you save on cost, you don’t compromise on quality. It might not be assembled in the USA, but it brings to the table same reliability as the D4.
III. Conclusion
In the vast ocean of timepieces, Vaer’s Solar Dive Watches are a beacon of quality, style, and functionality. From meticulous design details to the thoughtful degrees of customization and personalization, the D4 and DS4 are a great choice for a durable (yet highly sophisticated) off-grid tool watch. Whether you opt for the premium D4 or the budget-friendly DS4, you’re going to have a watch that keeps in you on time, and in good taste for years to come.
