Editorial
The LM Sequential EVO solves a problem most chronographs ignore: what do you time when two things are happening at once. Two fully independent chronograph mechanisms share a single movement but answer to separate pushpieces, letting you track overlapping intervals without sacrificing one to reset the other. In titanium EVO guise, it is MB&F's most practically focused watch.
MB&F collaborated with Stephen McDonnell, the independent watchmaker behind some of the most technically complex split-seconds work in contemporary horology, to build what is essentially two chronographs in one movement. The concept debuted in the Legacy Machine Sequential, a precious-metal dress configuration. The EVO variant followed in 2022, transplanting the mechanism into a 44mm titanium case with a more legible, sporting layout suited to actual use at a circuit or on a boat.
McDonnell's contribution was the dual-axis architecture: each chronograph runs on its own column wheel and coupling system, entirely separate from the other. The result is a watch you can realistically hand to a driver, a cyclist, or anyone who needs to time two things that do not start and stop together.
The movement is genuinely complex and MB&F's service network outside Geneva is thin, so factor in travel costs and potential wait times before buying. At 44mm in titanium the EVO wears larger than the dimensions suggest because the dial layout pushes subdials to the outer edges; buyers with smaller wrists should try it before committing. The dual-chronograph complication means twice the number of column wheels, coupling levers, and reset hammers to maintain, and service estimates reflect that complexity.
Earlier Legacy Machine Sequential examples in gold have appeared on the secondary market at steep discounts, which has created some pricing pressure on EVO references; expect grey market prices to sit meaningfully below retail but verify provenance carefully. Water resistance is rated to 80m, which is better than most complicated watches but not a specification to push casually.
