The Breitling Watch Source Forums

I believe the newer 3126 movement is also 3Hz.

To the OP though, if you are looking at something fairly comparable to the Daytona and would prefer an in-house movement why not take a look at the B01. Outside of Breitling you could take a look at some of the JLC Master Compressors, Blancpain Fifty-Fathoms, Panerais (as suggested), and IWC's, all make nice watches, and if you are not quite sure what you want yet it can't hurt to take a look. Sorry to just keep listing stuff but there are so many options, but I would say that Ulysse Nardin might make something that you would be interested in at a not too absurd price point, and although a little more expensive the Vacheron Constantin Overseas is fairly similar to the Daytona (except that it is better...).

Now I do very much like the looks of the chronomat (B01); but when the sales person told me that Brietling's in-house movement was too new to have an opinion on whether it is an equal or better movement than that in the Navitimer or the Bentley GT, it left me leaning back to the Navitimer or Bentley. I was hoping to get some comparison feedback on the quaility of Brietlings in-house movement from this forum......Thanks again for all of your advice!!
