When the Navitimer Chrono-Matic ref. 1806 came out it was powered by the automatic Calibre 11 movement that had an operating frequency of 19,800vph with a power reserve of 42 hours. For the later models, copy Breitling switched to the Calibre 12 that as the main difference, had a changed frequency of 21,600vph. One of the most remarkable features of the movement — and Breitling had to keep in mind in the development of the case — is the position of the crown at 9 o’clock. It’s something that definitely helps with the wearability of the 48mm case size.
The best quality fake Breitling SuperOcean Chrono-Matic ref. 2105 is pure vintage gold.
Speaking of the hexagonal “Pizza” case, I have to mention the high-end fake Breitling SuperOcean Chrono-Matic ref. 2105 you see in the second picture. Breitling released it around the same time as the Navitimer Chrono-Matic ref. 1806. Both are similar in that they use the same case and same movement.
Obviously, the dial of the waterproof copy Breitling SuperOcean is a little more colorful. Personally, I like it a bit more than the Navitimer. Add the mesh bracelet, and this is pure vintage gold. But the watch is tough to find, and if you do, it’s going for big money.
That’s not the case with the Navitimer. You can find the Navitimer Chrono-Matic ref. 1806 fairly easy. And prices are relatively affordable, starting at roughly 2,5K, moving up to around 5K for one in better condition. The coolest, in my opinion, is the version with a black PVD case. Although more difficult to wear because it will scratch easily, it looks amazing and visually doesn’t look like the 48mm watch it actually is. Either way, the Navitimer Chrono-Matic ref. 1806 is an iconic Breitling and the perfect vintage watch if you can wear a 48mm watch.
