The older models of Breitling are a bit harder to get. Trusty Time, TD, is someone who is able to help with that. BLS and GF do some models okay, same as KOR for the Navitimer, but the current Chronomat B01 is not done correctly by anyone, except an unknown factory which I saw being offered via Trusty time too. They use a Swiss movement and that one has the datewheel at the right position for the dial to have the date window at the right position (which is completely at the edge of the 6 subdial. With all others the date window sits way too high. Once you’ve seen this you cannot unsee it i fear.
