I think Breitling has tested long enough breitlight before introducing it on the market, plus it sports a high end manufacture movement that few manufactures can rival with Breitling except Hublot, Tag with the 02, Rolex, Chopard, Omega, Glashütte Original, IWC, JLC and Patek. Blancpain merely relies on frederic piguet movements which are not known for their over their long run durability under harsh conditions.The case is made of an innovative material and I do like the soberty of the watch to be honest.But once again this is just my personal opinion.
Best regards
