WATCH OF THE WEEK

Beautiful,stylish and waterproof!

Super nice watch, I scuba dive with it and can wear it out to dinner too! Smaller than most scuba watches so it looks great for everyday use.

This watch is one solid piece of quality dive watch! I have a 7 1/2 inch wrist so 44mm fits me well. It is well proportioned, great lume, and highly accurate. Great service to go along with it.

The fit on my wrist is perfect. The make is solid and beveled glass makes the watch stand out.

Icons Reborn

At Momentum Watches, our dedication to timeless design and exceptional craftsmanship has always been at the heart of what we do. That’s why we’re excited to bring back two of our most iconic models the UDT and Sea Quartz. These watches have earned their place in history, trusted for their durability, reliability, and purpose-built design.

By reintroducing these beloved timepieces, we’re not only honoring our brand’s heritage but also giving our customers the opportunity to own a watch with a true legacy. The UDT and Sea Quartz are more than just watches they’re a testament to our commitment to quality and innovation, built to stand the test of time.

IT’S A PASSION.

At Momentum Watches, we build rugged, reliable timepieces designed for adventure. As a Canadian brand, we specialize in dive, field, and tool watches that are built to last, with solid specs all at an accessible price.

One thing we’re especially proud of? Our watches are trusted by professionals, from firefighters to military personnel, and even the Mexican president, AMLO, has been spotted wearing one. We’re always looking for ways to make our watches better, like our new sailcloth straps with quick-click spring bars for easy swapping.

If you’re looking for a watch that’s built to go anywhere, we’ve got you covered.
