BRITTANICA ONLY WATCH

From the high seas to the table-top

BRITTANICA ONLY WATCH
 

BRITISH HERITAGE. WORLD-CLASS TIMEKEEPING

Transferring our attention from the ocean to dry land allows us to retain our obsession with accuracy while adding other qualities. Exclusivity and elegance are intrinsic attributes of the Brittanica.

The Brittanica table chronometer builds on Thomas Mercer’s expertise in marine timekeeping. Encased in a highly polished steel cabinet upholstered in fine white leather, the chronometer movement is sheltered behind a unique bas-relief dial. A set of extra-white crystals provides an all-round view on the Brittanica polished and bevelled movement. Sharp angles and straight lines form the geometric design of the elegant case.

 

ONLY WATCH

WATCH AND CLOCKMAKERS AIDING MEDICAL RESEARCH

Under the high patronage of HSH Prince Albert of Monaco, the Only Watch charity raises funds to carry out research into Duchenne Muscular Dystrophy. Its main fundraising event is the bi-annual Only Watch auction, featuring donations from some of the world’s most prestigious watch and clock makers. The 2015 sale, held in Geneva, invited bids for 44 one-off pieces, including the first Thomas Mercer Brittanica table chronometer.

 

DESIGN AND UNIQUE FEATURES

A STRIKING DESIGN. A SOPHISTICATED CHRONOMETER

British designer Jake Phipps has created a sleek octagonal case covered in soft white leather signed by Foglizzo, specialist in leather interiors for private jets and superyachts. The dial has an outer ring with anthracite coloured minute indices in bas-relief created by the galvanic deposition of ruthenium. Its inner circle shows a hand-painted blue constellations map and the Roman numerals and hands are polished stainless steel.

MATERIAL

The case is constructed in stainless steel upholstered in fine white leather.

.

 

FINISHING

The steel is hand-polished and the dial’s outer ring is dark grey through the galvanic deposition of Ruthenium.

.

DIAL

The outer ring is anthracite in colour, created by galvanic deposition of Ruthenium. The inner circle is hand-painted blue.

.

 

GLASSES

Providing an all-round view, the marine chronometer glasses are extra-white crystal.

Mechanism

CALIBRE TM0802

The mechanism features a fusee-and-chain transmission system that acts in a similar way to a gearbox, constantly changing gears to provide a consistent level of torque and stabilising the movement’s frequency. Ticking at the rate of 14,400 vibrations per hour, the spring detent escapement is visible above the dial and works in close conjunction with a balance wheel of ovalising type that is unique to Thomas Mercer.

“Synonymous with the Marine Chronometer, in its long history Thomas Mercer excelled also in every other form of chronometry. The highest form of authenticity is when a legend remains relevant in the contemporary world, thus the Brittanica unites modernity, high aesthetics and fine craftsmanship in a quintessentially British Table Chronometer.”
