The MB&F LM Sequential makes an immediate impression thanks to its dramatic design which showcases much of what are normally considered inner workings, as well as its novel interpretation of the chronograph as a complication. The 585 component movement from the mind of Stephen McDonnell is a tour de force of mechanical ingenuity, offering dual chronographs that can be operated simultaneously, or individually (or any combination thereof). The last thing this watch needs is more complexity and a depth rating, but that’s exactly what it’s getting this week with the introduction of the LM Sequential Flyback EVO, bringing flyback functionality to both chronographs and a depth rating of 80 meters. Because why not.
To be clear, the LM Sequential Flyback was first introduced in 2024, and what we’re getting this week is the EVO variation, which adds a titanium case and a bit more sealing around the edges along with some shock absorption in an effort to make it adventure ready. That might be an easy thing to roll your eyes at when it comes to a $230,000 watch, but make no mistake, I have seen owners put these watches to good use on the go. There’s a reason that brands like Richard Mille have such a broad appeal when we see them used in extreme situations, and it’s no different here.
As we saw with the first LM Sequential Flyback, the sub-dial situated at six o’clock, which is used to actually tell the time, has been placed at an angle to separate itself visually from the chronograph works. On the actual plane of the dial we find a bevy of activity to support the dual chronographs and the minute totalizers set above them. Keeping watch over all of this is the suspended balance wheel, which is connected to the rest of the escapement under the dial (split escapement). The drama is over the top in every way, and it offers plenty of depth to get lost in along the way.
The first LM Sequential was released in 2022 as a fitting follow up to the bonkers LM Perpetual, and represented a revolutionary take on tracking time. The dual chronographs use something called a ‘twinverter’ to run in parallel in a number of ways allowing them to be used independently, split-second, lap timer and cumulatively. It feels bulletproof in use, and has only become more refined since its inception, which is on full display with the addition of flyback functionality.
The titanium case measures 44mm in diameter, and the domed crystal means a thickness of just over 18mm. If you’re looking to stay under the radar, this probably isn’t the watch for you, but it is surprisingly wearable thanks to the curvature of the case and the use of an integrated rubber strap. This example boasts an aqua blue dial plate, and will not be limited in production. MB&F
