Berneron is only three years old and already one of the names collectors watch most closely. Sylvain Berneron spent his career designing cars before he set up his own workshop, and the Mirage, launched in 2023, carries that background plainly. Its case is asymmetric, closer to a liquid shape than a circle, because Berneron lets the movement decide the outline rather than forcing the movement into a round case. The new Mirage 38 Miroir keeps that sculptural profile and pushes the idea further, rebuilding the calibre so that the movement is the dial.
A case shaped by what is inside
The Mirage 38 Miroir measures 38mm by 34mm and just 7mm thick, with a 42mm lug-to-lug, which keeps it firmly in dress-watch territory despite the unusual geometry. The case is 18k gold, offered in white or yellow, and the whole construction follows through on the material, down to the buckle and the spring bars. A hesalite crystal, treated for scratch resistance, sits over the front, and the caseback is solid. Water resistance is 30 metres, which is what you would expect from a watch built to be looked at rather than swum in.
The movement as the dial
The name Miroir points to the method. The new Calibre 283 is a mirrored reinterpretation of the original Calibre 233, and only around a fifth of the earlier movement carries over, mostly the barrel and the winding assembly. Everything else is redesigned. Rather than hide the mechanism under a sapphire dial, Berneron uses the architecture of the calibre itself as the surface you read. Steps and split lines in the mainplate and bridges act as markers, a sector of guilloché stands in for the hours, and two curved gold hands show the time with the hour hand set above the minutes. There is no separate seconds counter; the seconds wheel simply turns in the open, doing the job without an extra dial to interrupt the composition.
Calibre 283
The movement is compact, 30mm by 28mm and 2.83mm thick, with 135 components and 17 jewels. A free-sprung balance runs at 21,600 vibrations per hour, and two barrels give a 72-hour reserve. The finishing list is long: guilloché, anglage, colimaçonnage, laser engraving, cerclage, traits tirés and nuagage. What matters is less the list than the intent behind it. Most of the parts are exclusive to Berneron and shaped to sit with the rest of the design, so the spokes of a wheel or the outline of the balance bridge read as part of the picture rather than as generic components dressed up.
Price and availability
The watch comes on a Barenia leather strap, 20mm tapering to 16mm, with a gold buckle. Berneron has also developed an integrated-looking solid-gold bracelet, in white or yellow gold, that turns the Mirage into something closer to jewellery. Production is deliberately small. First deliveries are scheduled for October 2027, and the initial Series A will run at 36 pieces per colour per year for ten years. On the strap the Mirage 38 Miroir costs CHF 72,500 excluding VAT, rising to CHF 130,250 excluding VAT on the gold bracelet. It is a narrow proposition, and an honest one: a watch whose whole argument is that the mechanism and the design are the same thing.
