OMEGA's Co-Axial calibres

are unlike any other mechanical watch movements

in the world.

At the heart of each one is the

first practical watch escapement to be invented in some 250 years.

In short,

the Co-Axial escapement reduces friction in the movement,

resulting in superb long-term chronometric performance.

The Co-Axial story is told in near-microscopic detail:

An anchor with three ruby pallet stones,

weighing an impossible-to-imagine four thousandths of a gram.

A three-level Co-Axial escapement wheel

that can bear more than half a billion strains each year.

A silicon balance spring

that has one-seventh the weight of a grain of rice.

It was up to our master watchmakers,

who have made horology an art form,

to advance Co-Axial technology

from theory to practice.

Assisted by purpose-built, state-of-the-industry instruments,

this team of visionaries, innovators, and pragmatists

has created OMEGA Co-Axial calibres:

nothing less than a turning point

in the history of mechanical watchmaking.
