jamonClosest I’ll probably ever get to one of these is at the airport duty free shop. So here’s an obligatory #watchesofmastodon wrist-shot of an Omega Seamaster 300 with coaxial escapement.

@jamon "coaxial escapement" sounds fancy. I have no idea what that means.
@Xavier here’s a video of George Daniels who invented it explaining how they work: https://youtu.be/0UOU36cJgZY - the short version is that it reduces friction where it matters most in a movement, which makes things more reliable, need less service, and less lubrication. Omega seems to have gone all in on using them
