Both the movement and mechanism of the Martin-Baker have been designed to “float” in a controlled manner within the Bremont-patented Trip-Tick® case. As you can see, the reference I had for the day — the MBII/OR — featured an orange central barrel. This floating effect was achieved by attaching the inner case to a flexible ring. In doing so, shocks to the movement are minimised and shock energy absorbed. On the day, working in teams of four, we had to navigate tyre flips, sled pulls and ring dips. There is no doubt, at 43mm, the Martin-Baker isn’t a small watch. I was certainly aware of it on the wrist for the first hour or so of the day, but following that, it became part of my being. It felt bulletproof and rugged. And sure enough, it was still ticking away afterwards!
