The Best Ultra-Thin Watches You Can Buy in 2022

Ten mechanical watches that clock in under 9mm.

The pursuit of creating ultra-thin watches is decades old, but the effort has heated up in modern times. Piaget, for example, is at the forefront with the current thinnest mechanical watch in the world, measuring an impossible 2mm by incorporating the movement into the case design and forgoing a dial. Bulgari's Octo Finissimo line took the title from Audemars Piguet for the thinnest perpetual calendar, following past records such as its Octo Finnisimo Tourbillon Automatic, simultaneously the world’s thinnest tourbillon and automatic watch (and, as such, also the thinnest automatic tourbillon).

While they’re fun examples of how much watchmaking can be crammed in a small space, this super slim philosophy has been applied to a greater number of watches that, while a bit thicker than those record-holders, still retain the svelte design and packaging that make ultra-thin watchmaking so appealing while remaining realistically wearable. While there’s no set definition of what makes a watch “ultra-thin” versus just plain thin, the mechanical timepieces below come in at under 9mm in height. Some are even a fraction of that.

Hamilton Jazzmaster Thinline Auto

$945.00

Most super-slim watches under a grand rely on a hand-winding movement to keep the overall case thickness down, but the Hamilton Jazzmaster manages to pack automatic winding and still come in at just under 8.5mm in height and $1,000 in price. The Jazzmaster Thinline is available in a handful of different dial colors, each with shimmering sunray finishing, and pairs its slim case with a set of old-school sculpted lugs.

Junghans Meister Driver Handaufzug

$1,290.00

The Junghans Meister Driver’s svelte case was made possible by the slim, hand-winding Peseux 7001 movement. Though thin watches will be styled dressily, this one is heavily Art Deco design, a nod to the speedometers Junghans made back in the early 20th century.

Nomos Tetra Neomatik 39
Tetra nomos-glashuette.com
$3,860.00

At just 7.3mm thick, Nomos’s dressy, square Tetra is incredibly thin for any timepiece, let alone an automatic. That’s thanks to Nomos’s in-house DUW 3001 caliber, a super-flat movement that’s only 3.2mm thick. The clean, Bauhaus-inspired dial design and delicate lugs are the perfect accouterments to the Tetra’s minimal proportions.

Cartier Drive Extra-Flat

$6,150.00

The Drive de Cartier debuted initially in 2017 as a gold model, but at SIHH 2018, the brand finally brought it out in stainless steel, dropping the price to under $6,000 but retaining the attractive squircle case design and 6.6mm thickness. Inside, the watch is a Cartier-branded version of the 430P caliber from Piaget, Cartier’s corporate cousin and a pioneer of crazy-thin watch movements.

Chopard L.U.C XP
chopard.com
$8,810.00

Chopard’s watches generally tend to skew more classical, but the XP is a decidedly modern take on the ultra-thin dress watch. The clean dial is finished with vertical brushing, giving it the look of raw metal, while the numerals and hands have been treated in an eye-popping blue. (A cashmere strap is also a unique addition). The scant 7.2mm case houses an in-house automatic movement from the brand that comes in at just 3.3mm thanks to a micro-rotor design.

Bulgari Octo Finissimo Watch

$12,200.00

The Bulgari Octo Finissimo is one of the most distinctive watches out there — and also just crazy-thin. The in-house movement itself is just 2.23mm. It comes in an expanding range of versions from those with stainless steel or titanium cases to a ceramic model, as well as those with solid or skeletonized dials. The bracelet option offers a look quite unlike anything else, and its striking angular design is surprisingly comfortable on the wrist.

Audemars Piguet Royal Oak “Jumbo” Extra-Thin

$31,300.00

The classic shape of the Royal Oak is iconic, and its sleek lines are even more enticing in ultra-thin guise. While the ultra-thin variants have existed in the greater Royal Oak lineup for some time, this year the brand released it in a mix of platinum and titanium. That may seem like an odd duo, but the rugged, brushed look of the titanium mixed with the polished look of the platinum bezel and end links offer up a unique take on two-tone design.

Vacheron Constantin Historiques Ultra-fine 1955

$39,700.00

When it first launched in 2010, the Historiques Ultra-Fine 1955 was the thinnest mechanical watch in the world, clocking in at a still impressive 4.13mm. Other watches have eked their way to even slimmer proportions, but the Historiques remains a beautifully restrained timepiece. At just 1.3mm thick, the in-house caliber 1003 hand-winder inside is a gem, too. It was first released by the vaunted watchmaker back in 1955.

Piaget Altiplano Ultimate Concept
piaget.com
$450,000.00

Here it is: the thinnest mechanical watch in the world, and most likely the thinnest watch you could ever want. At 2mm thick (yes, that's the case measurement), it makes you wonder if a thinner watch is even physically possible while maintaining structural integrity or whether making it any thinner would make any difference. This incredible micro-engineering feat is the culmination of the brand's longtime quest for ever thinner watches and world titles.
