The OMEGA Co-Axial calibre 9300/9301

The OMEGA Co-Axial calibre 9300/9301 is the dramatic next step in the revolution in mechanical watchmaking that started in 1999 with OMEGA's launch of the Co-Axial escapement. Not only does the new movement deliver superb timekeeping performance, it is the first of OMEGA's exclusive in-house Co-Axial calibres to incorporate a chronograph function.
The innovative column-wheel chronograph has 12-hour and 60-minute counter hands placed on the same sub-dial at 3 o'clock. This familiar arrangement of the hands, which recalls the hour and minute hands on the main dial, enables intuitive reading of the chronograph. It also has a central chronograph seconds hand and a small seconds hand on the sub-dial at 9 o'clock.
The outstanding reliability delivered by the combination of Co-Axial technology and the silicon balance spring is such that OMEGA delivers its Co-Axial watches equipped with silicon balance springs with a full four-year warranty.

This new movement is really starting to grow on me, particularly the blue POC

These new fangled movements. It probably doesn't even have a proper wobble like the 'ol 7750!

There aren't many movements out there that are more nicely decorated than this one. Thank goodness for display backs.

I've always been envious of watches with display case-backs. They're also great for showing non-WIS: "this is how a real watch works". 😉

Exactly.... I was showing off the display back on my Breitling Navitimer 01 to every one. The caliber 01 movement was one of the nicer parts of the watch. Unfortunately I didn't like it in person as much as I did in photos so o sold it.

Is the Cal 01 based on the El Primero?

I don't think so. The 01 movement is an in house Breitling movement. It doesn't beat as fast as the el primero so I don't think they're related.

Here are some photos of it. It has a beautiful movement but no where near as beautiful as the Omega.
