The movement in the Breitling is a close copy to the original movement used in the Breitling. The Daytona's movement is a hack and not even close to a copy of the original movement. Because of this, the Daytona is going to have more problems. It has serious power reserve issues due to all of the extra gearing they hacked in there.
Now, if you can find a franken Zenith as slayer mentioned, that is the best. But, prepare to spend a ton of scratch. Not worth in IMO. Well over $1000.
