World’s THINNEST watch is unveiled: $1.8 MILLION RM UP-01 Ferrari is thinner than 10p coin


Earlier this year, Bulgari hit the headlines after unveiling the world’s thinnest watch – a stunning model measuring just 1.80mm thick.

But the jewellery brand has already been gazumped thanks to Richard Mille’s new watch, which it designed in collaboration with Ferrari.

The RM UP-01 Ferrari is just 0.05mm thinner than Bulgari’s Octo Finissimo Ultra, and now claims the title as the world’s thinnest mechanical watch.

‘At just 1.75 millimetres thick, the RM UP-01 Ferrari constitutes a triumph of technical prowess and exemplifies a new approach to watch mechanics in which technicity more than ever dictates aesthetics,’ Richard Mille explains on its website.

However, if you’re hoping to get your hands on the record-breaking watch, you’d better get saving – the RM UP-01 Ferrari is on sale for an eye-watering $1,888,000 (£1,571,929).

While Richard Mille set out to develop the world’s thinnest watch, it explains that the RM UP-01 Ferrari is ‘far from begin a “concept watch”.

‘Even in the realm of extreme flatness, we were determined to make a watch that met the same validation requirements as all our other models,’ it explains.

‘In this quest for absolute flatness, we had to offer a watch that, far from being a “concept watch”, was up to the task of following a wearer’s daily life.’

According to the brand, the watch took more than 6,000 hours to develop and test.

Richard Mille opted for grade 5 titanium for the baseplate and bridges – a highly corrosion-resistant alloy.

‘The alloy is 90 per cent grade 5 titanium, six per cent aluminium and four per cent vanadium,’ it said.

‘This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automotive industries.’

The baseplate sits within a rounded rectangle case, with the time indication located at the centre of the top half. 

The watch is wound manually, and has a power reserve of around 45 hours.

A function selection is integrated into the bezel between 10 and 11 o’clock, and allows users to select the winding or hand-setting function.

‘Setting the time or winding the barrel is then possible by turning the second crown located between 7 and 8 o’clock,’ it explained.

If you want to get your hands on one, you’ll have to be quick (and have a hefty budget).

Its grand reveal comes just three months after Bulgari unveiled the Octo Finissimo Ultra, which is a bargain in comparison at £332,700.  

Watch experts at Hodinkee described the new record as ‘positively insane.’

Writing on its website, it said: ‘Who doesn’t love a world record? I think it’s positively insane that we are seeing this watch so soon after the announcement of the Bulgari Ultra. 

‘You have to think that RM had this in the prototyping phase by the time that watch was announced. 

‘It’s really amazing to see, despite so much ubiquity in the watch world today, that brands are continuing to push the limits of what watchmaking can be.’
