MB&F Legacy Machine Perpetual Titanium Hands-On

MB&F Legacy Machine Perpetual Titanium Hands-On Hands-On

Introduced in late 2015, the Legacy Machine Perpetual is one of MB&F’s most complicated watches. It is also arguably the most visually arresting. Since its launch, the Legacy Machine Perpetual has been made available in platinum as well as white and red gold. Now, there’s a new version in titanium. This is the new MB&F Legacy Machine Perpetual Titanium.

Like all other Legacy Machine watches, the Legacy Machine Perpetual’s balance wheel takes center stage on the dial. This presents a challenge because traditional perpetual calendars rely on a lever to change the various perpetual calendar indications on the dial. This means no complication can be put over the lever, which obviously won’t do for a Legacy Machine. As a result, significant rethinking was required to allow the balance wheel to take center stage on the Legacy Machine Perpetual watch.

The MB&F Legacy Machine Perpetual Titanium has a case that is identical to previous Legacy Machine Perpetual watches. Case diameter is still 44mm, but it is now made out of grade 5 titanium. The use of titanium has significant aesthetic and practical effects. Titanium has a unique hue that is unlike that of steel or gold. Additionally, it is hypoallergenic (great for people with sensitive skin) and it is very light but strong.

The use of titanium aside, the other major change is the dial. The dial configuration is unchanged, with sub-dials for the time, day, month, and date at 12, 3, 6, and 9 o’clock respectively. The big change is the color of the dial. It now has a striking emerald green dial that looks pretty awesome, at least based on what we can see from the press images.

The movement is the same integrated hand-wound perpetual calendar caliber that was developed by Stephen McDonnell, a self-taught movement designer based in North Ireland. Not only was it designed to be visually interesting, it was also designed to be foolproof and easy to use. It is made out of 581 components and has two mainspring barrels providing a power reserve of 72 hours.

All things considered, this is one of the more fun versions of the Legacy Machine Perpetual. The white gold version with a purple dial is probably just as funky and the red gold version is the king of bling, but this new titanium model has the advantage of a new case material and an equally interesting dial color. The new MB&F Legacy Machine Perpetual Titanium is priced at 148,000 CHF and will be limited to 50 pieces.

    I love this watch, but titanium is among the least desirable case materials for me. I’d rather the effort were put into a new steel hardening strategy or proprietary steel alloy. No one that was considering this watch in precious metals didn’t buy it because of the weight.


    look a chicken bone……….just kidding.
    looks superb though too large at 44 for me and of course way too pricey. 145G in Ti seems a bit of a stretch, would really expect precious metal at that price point. the color combo is really striking.

    • But maybe an upcoming version is steel will only be $125K.

      Hand winding for a perpetual seems wrong unless it is a daily wear watch and as much as I like Legacy Machines, I can’t imagine an MB&F owner wearing the same watch every day. Guess you have to have Jeeves your watch valet do the winding chores.

        Good call about it being manual. It would very be a pain to reset the thing almost daily. But yes this is where Jeeves comes into play 😉

    KF & C ?

    Such stuff as dreams are made on! I wouldn’t normally consider a PC, but McDonnell’s mechanism is such a step forward that I would happily grace my wrist with any of the variants!
    p.s. Anyone got 150,000 CHF rattling about in the back of their sofas?

  • Raymond Wilkie

    You need to see this alive. I could walk off the edge of a cliff just staring at it. Absolutely gorgeous.

    I very much enjoy the way MB&F shows off the balance while keeping the design elegant rather than just punching a big ugly hole in the dial.

    50 lucky bastards…

    Stunning. Not sure about the titanium really (white gold with purple sounds awesome) but wouldn’t say no!

  • hatster

    Stunning, engineering genius, would never be worn to tell the actual time but then that is not why you would buy it.
