We are incredibly proud to stand behind Craig and Zach Lumsden as BOMBERG ambassadors.

A father and son who race together at the highest level, no factory backing, no corporate safety net, just shared passion and an unshakable belief in what they're building. That's the kind of spirit BOMBERG was made for.

As they take on the 2026 Pirelli GT4 America championship in the #413 BMW M4 GT4 with Flying Lizard Motorsports, we couldn't be more honored to have them represent what this brand is about: audacious, unconventional, and driven by something deeper than the clock.

Their story is one of legacy, grit, and the kind of bond that only the track can forge. From rally raids and Baja endurance to a race win at VIR and a podium at Indianapolis, Craig and Zach have proven that Colorado Motorsport belongs on the biggest stages in motorsport.

This season, we're with them every lap because at BOMBERG, we don't just build watches for the people who race. We stand with them.
