TAG Heuer Monaco Speed 12 might just be the wildest watch the brand has ever made

TAG Heuer has unveiled the Monaco Speed 12 at the Formula 1 Louis Vuitton Grand Prix de Monaco 2026 today, it’s a limited edition of just 50 numbered watches – and the concept is genuinely unlike anything else in the Monaco family’s history.

Rather than a traditional hour display, twelve rotating pistons circle the dial. Each one is shaped to mimic the cylinders of a high-performance V12 engine.

As the minute hand completes a full rotation, one piston snaps back to position while the next turns 90 degrees to reveal the new hour. It’s a reinterpretation of the jumping hour complication, and it looks absolutely spectacular in motion (so spectacular I’ve included a video below).

The movement powering all of this is the automatic Calibre TH84-00, developed in collaboration with La Fabrique du Temps Louis Vuitton.

It builds on the Spin Time movement, a system originally conceived by LFTLV founders Michel Navas and Enrico Barbasini, and has been reinterpreted here specifically for this watch.

The case is Grade 5 titanium, measuring 40mm across the signature square Monaco form.

Four DLC-coated open-worked arches suspend the movement within it, giving the dial a depth and transparency that makes the whole mechanical spectacle visible from almost every angle.

A square sapphire bezel frames it all, with a domed sapphire crystal on top and a see-through caseback underneath.

The dial itself looks more like an car engine than a watch moment – vertical grooves at the centre evoke engine covers, and the skeletonised minute hand resembles a speedometer needle.

The Speed 12 is finished on a black rubber strap with textile embossing and red hand-stitching.

The TAG Heuer Monaco Speed 12 is priced at $87,000 in the US and £66,000 in the UK. It’s available from December.
