Overall, great workmanship and very nice, discreet design. Finally, the solar function induced me to buy. Remains to be seen how long because in reality such a battery will last before it needs replacing. Overall, the power reserve is indicated by 6 months. This is achieved with 5 hours charging time in full sunlight with no cloud cover, according to operating instructions. Alternatively, artificial light can be used. The computing and especially Umrechenfunktion I rate also good although one needs to have very good eyes, because the numbers of the inner ring be very small. (Whether this is different at a Breitling I venture to doubt). I am a pilot himself and found all the scientific unit. The bezel can be rotated with optimum resistance and makes a good impression. The stopwatch is running in 1 / 5sek. increments and is very pleasant to use. This clock has even an alarm function which evokes with a subtle tone up to 20 seconds! As a small negative point is the Armabnd perform, it could be of a higher quality. But can be replaced quickly. The Crown is not to screw it, I frankly see as big plus since I already a thread broke. However, the clock is wassdicht to 10 bar. I particularly like the arrangement of the light elements in the dark, the time can still be determined with great accuracy.
Overall 5 stars for a great clock at a reasonable price that will hopefully never need the repair!
