Building on the success of their first sports model GMT Sport from last year, Greubel Forsey today unveiled a new timepiece – the Balancier S – that brings a more leisurely air to the brand’s haute horology signature. It is water-resistant to 100 metres is fitted with an integrated rubber strap – two details that you wouldn’t associate with Greubel Forsey not too long ago, these timepieces have always eschewed a more serious tone.

The Balancier S has an arched ovoid shape

The new timepiece riffs on the Balancier Contemporain from 2019 and borrows designs codes from its sporty sibling the GMT Sport, but the Balancier S is very much its own beast. The case may seem familiar to those who have handled the sports watch, the unique arched ovoid shape and integrated lugs and strap make for an ergonomically-designed wristwatch.

Unlike the Balancier Contemporain, which was the first Greubel Forsey wristwatch under 40 mm, the Balancier S is no shrinking violet. Though at its widest (bezel diameter), the case measures 45 mm and the case height (with the curved sapphire crystal) is 15.60 mm, the watch only weights 110 gm (including the rubber strap) thanks to the use of titanium. Even the screws that hold things together on the case are made from titanium.

The satin-finished bezel engraved with Greubel Forsey’s key values dips and arches around the edges of the case. The rubber inserts on the crown and caseband assure excellent grip, but they can also be changed easily to match the color of the rubber strap. When viewed from above, the case may appear circular, but it is distinctly an ovoid from other angles. 

The escapement is set at a 30 degree angle to the horizontal plane

The multiplane dial sees the return of two key elements: the GMT Sport’s suspended arch central bridge that holds the curved gear train and curved hour and minutes hands is back, so is the large balance wheel (12.6 mm) first seen on the Balancier unveiled at SIHH 2017. The surfaces have a frosted finish and the escapement platform (which holds the balance wheel, hairspring and escapement) is set at a 30-degree angle from the horizontal plane of the movement. This inclined construction offsets the effects of gravity on the accurate running of the movement.

The suspended bridge holds the curved gear train

Greubel Forsey timepieces are renowned for their immaculate finishing techniques, all executed by hand. Consider the multi-level titanium balance wheel bridge for example - it is black-polished at the top but the surface is circular grained as it slopes downward and the base is again black-polished. The interplay of brushed and polished surfaces play off the light well on the dial. The arched central bridge has black-polished edges and a blackened center area, the open-worked hands also have a black-polished finish and red lacquered tips that really pop on the dial. A power reserve indicator is placed near the 1 o’ clock position while a rhodium-plated gold small seconds dial sits snugly next to the large balance wheel. A twin barrel connected in series ensures a power reserve of 72 hours.

It is hard to polish and finish titanium bridges and mainplates

The exhibition caseback again showcases the atelier’s impressive finishing skills. The titanium bridges have a frosted finish and raised black-polished edges. Expect to see polished bevels and countersinks, circular and straight graining highlight even the smallest surfaces. It’s not easy finishing titanium surfaces by hand, so it’s no surprise that it takes about two months for a craftsman to work through one of these movements.

The watch is paired with a rubber strap fasted by a titanium folding clasp to reinforce its sporty character. Limited to just 18 pieces, this exclusive timepiece is priced at CHF195,000.
