The BB54’s real power lies in the fact that it has a truly vintage feel with a thoroughly modern movement. It comes equipped with Manufacture Caliber MT5400, which displays hour, minute, and second functions and has a healthy 70-hour power reserve. And even though it’s vintage-inspired, there is a distinct lack of “fake patina vibe.” Obviously, everybody’s initial inclination is to make a straight comparison to the BB58 – a hugely successful watch for Tudor. And even though these two watches are extremely similar, there is a lot more to compare than just differences in size. The BB54 is much slimmer and cleaner than the 58. The hash marks are gone (making it slightly harder to time things), there is no red triangle at 12, the crown is significantly smaller, andit has less gilt accenting, which makes it more cool-toned, while the dial is no longer matte but a glossy satin finish.
