Introducing The TAG Heuer Monaco Speed 12 Is An Ode To The V12 Engine

For this year's Monaco Grand Prix, TAG Heuer pulled the covers off the Monaco Speed 12, which the brand has created as a love letter to the 12-cylinder engine. Monaco itself is a fitting place to unveil it, given the brand's enduring connection to motorsport, and no other city on earth howls to the piercing sounds of a V12 quite like it.

In their textbook Techniques d'Avant-Garde style (hence TAG, if you didn’t know), the Monaco Speed 12 takes that motorsport inspiration and blends it with the traditional square Monaco case, this time in titanium. Throw in TAG’s engineering-driven philosophy, and we’ve got TAG Heuer’s first-ever jump hour watch.

Whilst still a jump hour, the Speed 12 doesn’t operate like your usual digital display jump hour. Each time the minute hand completes a rotation around the dial, one of the 12 pistons corresponding to the hour markers makes a snap 90-degree rotation to reveal an engraved black-lacquer Arabic numeral. Only the current hour piston is on show at any given time.

Powering the Speed 12 is a brand new TAG Heuer movement, the Calibre TH84-00, developed in-house at LVMH in collaboration with La Fabrique du Temps Louis Vuitton. If you’re looking at the Monaco Speed 12 and drawing similarities to the Louis Vuitton Tambour Taiko Spin Time, you’re not wrong, as their spinning hour indicators function in the same arrangement as the Spin Time. The core movement that powers the Speed 12’s spinning hour functionality was first developed by the extraordinary Michael Navas and Enrico Barbasini way back in 2009, before LV acquired La Fabrique du Temps two years later.

From that, TAG Heuer has entirely made it its own, fashioning the 12-hour markers on 12 rhodium-plated pistons that surround the movement, sandblasted with satin-brushed piston rings.

Above the movement, TAG has fitted a thin chapter ring accented with red hour markers matching a skeletonised and red-tipped minute hand, the only hand present on the watch. The hands and chapter ring are designed to be as unobtrusive as possible to not obstruct the movement on show. TAG Heuer claims the movement finishing and the rhodium-plated central piece with brushed vertical grooves are inspired by the design of engine covers on supercars, and you can certainly see that the inspiration for the hands and chapter ring comes from the design of performance car instrument clusters.

The Monaco Speed 12’s case is a brand new one from TAG Heuer: a 40mm grade-5 titanium ensemble that's primarily brushed with some polished chamfers. It’s got a domed and bevelled sapphire crystal up front and a flat sapphire display caseback on the rear - it creates a nice window that draws attention to those piston hour markers, and the crown stem is cleverly obscured behind the 3 o’clock piston. On the wrist, this should create a nice mystery dial effect with the movement, dial, and pistons seemingly suspended within the case.

The current Monaco lineup doesn’t include a titanium 40mm time-only case, so this piece nicely rounds out the lineup and fits in well with their Avant-Garde Horlogerie collection. Whilst we don’t yet have measurements for the case thickness, the LV Tambour Spin Times which use a similarly developed movement measure in around 12.5mm thickness, so whilst this is an informed guess, we can assume this Monaco will share a similar height on the wrist.

The Monaco Speed 12 is strapped with a textile-embossed black rubber strap with red stitching to match those dial and hand accents, and of course, there’s a matching titanium TAG Heuer deployant clasp. 

It's limited to just 50 pieces: whilst we don’t yet have pricing in Australian dollars, it’s ticketed at €77,000, so expect it north of A$125,000.

After seeing Louis Vuitton iterate on the Spin Time jump hour format in a few different watch designs, I was silently hopeful that we would see the complication come to life under a different LVMH brand. It’s such a clever bit of watchmaking, so keeping it locked to one brand would be wasting potential. I think TAG Heuer is the perfect first stop for a spin time format outside of LV, and the 12 pistons for 12 hour markers design concept is quite clever. It’s further fitting that pistons obviously move up and down in an engine, so adding some movement to the pistons in the Monaco feels like a natural fit conceptually, not just slapped on to make it motorsports themed.

I also think the Monaco line was the perfect choice for this complication, given that it definitely carries the most motorsport DNA in the modern TAG lineup. In name, too - no other city is quite so acclimated to the 12-cylinder quite like Monaco, both today when Lamborghini Revueltos sprint through the Monaco Grand Prix track tunnel on a Sunday morning, or back in the early 70s as 12-cylinder monsters howled around the city for the F1 title on Grand Prix day.

I suspect that the Venn diagram of TAG Heuer Monaco diehards and V12-loving petrolheads probably has a lot of crossover, so keep an eye on the wrist of the next Ferrari 12Cilindri or GMA T.50 driver you see, and you might catch a glimpse of one of these limited Monaco Speed 12s...
