Revisiting Co-Axial: Getting rid of a dilemma (Part I)

Revisiting Co-Axial: Getting rid of a dilemma (Part I)

Often we face questions about whether Co-Axial signifies a specific sort of development or if it is some specific evaluation applied to the Omega calibers. Since it’s been quite some time we discussed it last, I wish to return over the entire thing to clear the confusion once and for all.

Firstly, Co-Axial is not an invention by Omega. It has an English origin; credits go to Dr. George Daniels for creating this escapement mechanism that all around beats the traditional Swiss switch escapement from several aspects. Presently, there’s also something called the Extra Flat Co-Axial Escapement, however for the present, we’ll keep it out of this discussion.

So the hypothesis goes like this:

The co-axial escapement has 3 jewels adorning the bed fork while the equilibrium wheel has one. The job they play is entirely different than in the Swiss switch escapement mechanism. In the SLE, the jewels on the bed fork, firstly, receive impulses from the escape wheel; next, they lock the stuff train to receive the following impulse after the equilibrium returns to open it.

The co-axial escapement, then again, separates these roles. Here, two jewels receive impulses and the other two play out the locking action. Be that as it may, this is not what Dr. Daniels needed to do yet rather, a side impact of his achievement. Be that as it may, let us set out the differences by points, which will additionally facilitate the understanding of how the two work.

  • Swiss Lever Escapement: The impulse from the mainspring to the equilibrium wheel travels via the bed fork as the escape wheel slides across the gem’s impulse face. The escape wheel tooth at that point move towards the direction of the tangentially applied power to its circumference, moving the bed fork away almost to 90o to the power. This results in the least efficient transmission of the force.
  • Coaxial escapement: In this case, the coaxial wheel delivers the impulse radially to the bed fork. The impulse gem receives the impulse and moves in the same direction, which helps it to receive almost the entire energy created while minimizing the sliding action drastically. The impulse is received in the opposite direction, directly by the impulse gem that stays connected to the balance.

Okay, most of the readers will not find the engineering an alluring subject to go ga-ga over; what they need to know is the way it is going to benefit them. So here we go:

  1. In the coaxial escapement, the absence of sliding action removes the requirement for lubrication.
  2. No lubrication on the impulse jewels means there are no chances of breaking down of the lubricant, which otherwise affects precision. All the more consistently exact timekeeping, that means.
  3. Longer service intervals.
  4. Special synthetic lubricants on the locking jewels have longer life. Be that as it may, these lubricants function more as cushioning agents for the locking action.

Surely, you will not get the softer and springier gold compound today that Dr. Daniels really used in his creation, however the steel used by Omega is a superior shock absorber that has zero requirement for a hydraulic cushion. That means, you truly don’t have to make a big deal about if your watch’s service is due.

Our next installment will discuss the types of the Co-Axial development; till at that point, this much will do.
