How do you make the world’s most accurate watch? Christopher Ward knows how, following the upgrade of its best-selling C70 Brooklands – and the award of a prestigious COSC certificate
C
hristopher Ward’s bestselling C70 Brooklands watch – part of the C70 Grand
Prix inspired collection – has been upgraded to chronometer standard with an ETA 251.232 movement in a limited edition of 200 pieces worldwide.
And, most importantly the watch has gained the prestigious Controle Officiel Suisse des Chronometres (COSC) accuracy certification. The C70 Brooklands
Chronometer is Christopher Ward’s first watch to be awarded certification
making areas. Watchmakers submit their movements to COSC’s labs to be tested against the international standards of ISO and DIN to gain chronometer status. Certification follows exhaustive testing. Movements can be tested for 15 days, in five positions and at three different temperatures against criteria set down in ISO 3159. Measurements are made each day with seven levels of accuracy tested. Failure at any level eliminates the movement from further testing. So how does this translate to the C70 Brooklands Chronometer?

by COSC – and it is an achievement of accuracy of which the company can be proud. The watch is now among the small club of only 3% of Swiss watch production that gains internationally recognised COSC certification. Chris Ward says: “We already knew that our watches combined the most stylish English watch design with the very best Swiss watch making expertise. Now we know that the ateliers we work with can attain the highest achievable standards of accuracy.” COSC is an independent, non-profit making watch accuracy verification organisation. Set up in the early 1970s it brought together testing labs that were formerly run by the Swiss Cantons in the watch

The Grand Prix-inspired series movement, the ETA 251.272, allows measurement down to seconds. The upgraded COSC movement, an ETA 215.232, has a fourth chronograph hand which allows timing to be taken down to 1/10th of a second.
The C70 Brooklands
Chronometer movement is engraved with its COSC serial number and each has a copy of its certification. Like all the watches in the Christopher Ward C70 series, the chronograph version is strikingly designed using a 42mm diameter case. As it recalls the Brooklands Grand Prix, it uses British Racing Green on the face, has a colour matched presentation box and is engraved to commemorate the event.
