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.
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.
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.
